[flexcoders] Question on extending components for Mobile Apps
Hello All, If I am to create custom components inside of Flash Builder for Mobile, does it always have to begin by extending the View Class? I'm not talking about custom controls, but Views that would contain a ton of custom controls (one being a Loader component). Up until now (for non-mobile apps), I've always started by extending the UIComponent Class since that is probably the most basic class to build upon. Thanks for any advice you can throw my way, Mike
[flexcoders] Problem with data displayed in Drop Down, versus actual underlying data
Hello All, I am banging my head on the wall with this issue - I have 1 dropdown control's dataProvider, tied to the remoting results of another dropdown's database query. You can keep selecting a different value from the primary dropdown, and the secondary dropdown updates the underlying dataset beautifully, BUT if you click the secondary dropdown to display the actual values, it still displays the list from the PREVIOUS database query. The interesting thing is, if you click an actual value from the dropdown, it selects the correct underlying value contained in the index position, although the displayed value is wrong (the value from the previous query). I am using Cairngorm for my framework - and have the model.returnedQuery tied to the secondary dropdown box - so whenever I kick off a command, the values automatically update, since the dataProvider is tied to the model. Do any of you, have any ideas as to what's causing this? Thanks in advance for all your help, Mike P.S. I am using Flash Builder 4 compiling in Flex 3.5 (this problem still existed when using Flex Builder too).
RE: [flexcoders] FlexBuilder on 64bit machine any good?
I've had pretty good luck with it so far - I have it running on 3 different laptops and 1 desktop PC - ALL are 64-bit Operating Systems. I should say that 2 machines are running Vista x64 and 2 are running XP x64 Edition. One weird part when running on Vista (if you are using ColdFusion) is configuring IIS - it's fairly involved and can be frustrating. Lots of articles on the net though regarding how to set it up. One cool thing too, is Adobe has a 64-bit version of ColdFusion - so it takes advantage of all the RAM. My laptops are all limited to 4 gigs of RAM, but my desktop has 8 gigs. I am still using my previous FlexBuilder.ini file, which of course specifies all the RAM preferences. As far as I know (at least in my case) FlexBuilder and/or Eclipse is still only 32-bit, so they are still bound to the 32-bit limitations. Overall - I had good luck with it.

[flexcoders] Help! - Creating MS Access data source using ColdFusion 8 (64-Bit) w/Win2k3 (64-Bit)
Greetings All - I am currently moving my Flex Application (which uses ColdFusion as the backend) to my customer's production server - and I am coming to grips with a frightening discovery: Microsoft has decided to drop JET support, for servers running in 64-Bit mode. For some reason, this also translates to ADOBE not providing a native Access ODBC Driver in ColdFusion 8 (64-Bit Edition). I understand that there comes a time in the software business, where we must abandon older technologies in favor of new. However, there is usually some advanced notice given, in addition to backwards compatibility options for people that simply can't conform to the new ways. As a company, WE have upgraded all of OUR servers software, to the latest technologies. But that doesn't change the fact that we have CUSTOMERS that provide data to us, using virtually the only portable Database format available (an Access .MDB file). I know this is the FlexCoders list and this is largely a ColdFusion question, but I can only assume that a large number of you have been faced with this problem it makes sense to ask for help here. With that said, has anybody come across any solutions, that would allow for creating an Access data source using ColdFusion 8 running on Windows 2003 Server (in a 64-Bit environment across the board)? If a solution isn't found on this, heads will fly around here - as huge investments have been made in order to launch this Flex Application. Thank you in advance for any information that could help shed some light on this problem. Mike
RE: [flexcoders] Could the Flex Gurus shed some light on this behavior?
Actually, looking at it like that, it makes total sense. I didn't realize by setting the Source property of another control, I was stealing away a Child from another Control.

I believe since the content is a DisplayObject, it's just falling under normal Flex parenting rules, a child can only have a single parent, so using the same content actually re-parents the content object to the new SWFLoader. If your navigation window is just a small preview of the total app, like it sounds like, you could actually create a new Bitmap from the content of your main SWFLoader and use that as a new UIComponent in your navigation window. Not sure if you'd run into effeciency problems with how often you'd have to re-copy the data, but sounds like it could work in your situation.

[flexcoders] Having difficulties cloning content within Loader Control
Hello All, I am attempting to clone a Vector Image contained within a Loader Control, and am having some problems. The only way I've seen this done before, is by using the Bitmap(loaderObject.content).bitmapData.clone() method, but maybe I am getting errors because it's a SWF File being loaded into the Loader, versus an actual Bitmap...

[flexcoders] Yahoo/Google Maps - Navigator Component
Hello All, I was curious if there were any examples, components, etc. which allow you to do the following: Imagine a large graphic or map taking up the entire Application Screen, and then a rectangular box (a fraction of the main graphic size) sitting in a static spot always on top, representing the image as a whole. Within this rectangular box Component, you can drag around a small rectangle which represents the present viewing area below. As the Zoom Level changes, the draggable rectangle dimensions change accordingly. For you Photoshop users, it's the Navigator Component - which lets you drag around the rectangular box within, and quickly Pan the image around in order to quickly access an area you'd like to work on (rather than having to use the scroll-bars). I believe Yahoo/Google Maps has this feature as well. Does anybody have a place for me to start, in order to learn more about how to do this, etc?

[flexcoders] Issue with ToolTips not auto sizing
Hello All, I am trying to create ToolTips, add them as Children, and apply the errorTip style to them. I have to do it this way, instead of using ToolTipManager. When using this method, the Border is extremely small, and is not aware of the Text width height. When you use ToolTipManager, you can pass the text parameter right in the constructor, which probably explains why it comes up at the proper size immediately (without having to set Width and Height manually). With that said, how can I use the errorTip Style with manually created ToolTips, and have it come up with the proper Width and Height? I am trying to avoid having to manually set the Width and Height parameters, but will be my last resort if necessary. Since you can't pass the Text property into the Constructor, are there any ideas on how to do this? Thanks in advance for any ideas, Mike
RE: [flexcoders] mx.controls.Text control not autosizing -
Thanks for the reply Alex - I think I may have used the wrong terminology in my initial question. When I said Content I was referring to Text or it's Text Property. I hope that changes things, if this question was to be re-addressed once again. I say that because why would a UIComponent need to ever handle the resizing of a Text component (in my specific situation)? The Text component should have intimate knowledge about the actual Text contained within it. And again, per the Flex Docs, if the Width and Height values are left blank, the control should size itself around it's Text. Now if I wanted the control to base it's width and height on it's parent container, than I'd completely understand where you are coming from. Like I said, I hope this changes things a little, and hope you can take a crack at this question again :) Many thanks, Mike From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Alex Harui Sent: Wednesday, April 16, 2008 8:43 PM To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] mx.controls.Text control not autosizing - Children are sized by their parent, so you custom UIComponent will have to setActualSize on the Text appropriately From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Mike Anderson Sent: Wednesday, April 16, 2008 3:21 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] mx.controls.Text control not autosizing - Hello All, I know there's been some discussion recently, regarding TextFields and having them grow automatically around their content.

[flexcoders] General list consensus using 'this' when referencing local vars
Greetings All,
Whenever I study code generated by seasoned programmers (i.e. all the
Adobe people supporting Flex on this list) as well as countless others
on this list, I notice that some use this when referencing local
variables contained within a Class.
The last thing I want to do here, is start a heated discussion regarding
best practices for programming. My goal on a daily basis, is to
better myself as a programmer, and I want to make sure that the code I
create, conforms to certain standards.
Could some of you please offer your 2 Cents regarding the
advantages/disadvantages of using this? Just a quick example:
package
{
public class myClass()
{
private var testVar:String;
public function myClass( value:String )
{
this.testVar = value;
// versus:
testVar = value;
}
}
}
Thank you all so much in advance, for any help you can offer regarding
this topic.

[flexcoders] Adding Shape Objects to Canvas control
Hello All, I am trying to add my custom shape objects (which create several different shape types), to a different type of container, and I am having some difficulties. From my experience, you can directly add a Shape (flash.display.shape) as children to UIComponents, but you cannot add them to a Canvas Control. When I try to add a Shape to Canvas controls, Flex tries to cast the Object as a UIComponent. My question is, how can I convert my custom shape objects, so that they can be added to Canvas controls? Do I need to wrap my objects into a different type of component (UIComponent). The reason I like Shapes, is because they are so lightweight - but if there is a better way, I'd be very interested in hearing about it. Thank you in advance for all your help on this. Mike
[flexcoders] When can I access the Stage Object?
Hello All,
In my main mx:Application I am attempting to add an Event Listener to
the Stage Object, after the CreationComplete Event is triggered. Upon
application startup, I get that wonderful error dialog stating:
Cannot access a property or method of a null object reference.
I want to play around with some validate() stuff, in order to speed up

private function onApplication_CreationComplete( event:FlexEvent ):void
{
stage.addEventListener( Event.RESIZE, onStage_Resize );
}
private function onStage_Resize( event:Event ):void
{
this.validateNow();
}
So the question is, is the Stage Object not yet available? Do I need to
place this Event Listener on a Child Object contained within my
Application?
Any thoughts on this would be greatly appreciated :)

[flexcoders] PrintJob Class driving me crazy!! - Please Help
Hello All, I have 4-5 Move/Scale functions that must place, the moment the PrintJob.start() command is given. The problem is, these functions are still modifying the Objects to be printed (scaling and moving), while the PrintJob is sending everything to the printer. I tried every which way, to modify all these Objects residing on the page being printed, before calling start(), but all my functions rely on information not available until the PrintJob.start() method gets called (like Page Size and Margin Size). I feed the Page Size into a function that properly scales the page (and specific Objects which reside on that page) being added to the PrintJob. If I use too many callLater functions once the PrintJob.start() method gets called (in hopes of the delay giving the scaling functions a chance to finish), it errors out since the page never gets spooled. How is everybody else dealing with this issue of being forced to call start() in order to gain access to the Page Size information, and hope that their functions all finish in time, by the time the page gets spooled to the printer? Thanks in advance for all your help on this, Mike
RE: [flexcoders] Question on calling multiple Functions in sequence
Thank you Tracy and Eric - this DOES help me a lot -
But I need to ask, what facilities are built into the FlashPlayer, that
guarantees that Function2 doesn't run until Function1 not only executes,
but actually FINISHES?
Doing computations is one thing, but when you are doing scaling
functions, or anything else that really doesn't provide any feedback one
way or another when it's actually finished (scaling an object in this
case), how can the containing function really KNOW?
I know these may be novice questions, but these types of issues have
been nagging me for a long time. The more I can understand what's
really going on under the hood, the more effective of a programmer I can
be.
Thank you again for all your comments - please keep them coming :)

When dealing with things inside the flash player - you need to deal with
it as if it was single threaded - because generally, it is. In your
example, the functions would be called in order, one after another...not
all at the same time as you may think so lets say you had an example
like this
var myNumber:Number = 0;
private function doThisFunction():void{
myFunction1();
myFunction2();
myFunction3();
}
if function 1 added 10 to myNumber, function 2 multiplied it by 5, and
function 3 subtracted 12 - it would happen in that order exactly - and
you can count on that - so your final result would be 38
hope this helps

RE: [flexcoders] Question on calling multiple Functions in sequence
See, THAT is what I am talking about - regarding the UI still rendering,
while the PrintJob is being sent to the printer.
This where I am running into problems -
I have an idea on how to get around this - but I need to know which
Event to listen for, that directly relates to the Object I am scaling.
If I know which Event to listen for, I can set a local flag to 'True' -
and if a certain Event fires, with the variable being 'True', then I can
dispatch a custom Event, which my Printer Dialog Window listens for.
The Custom Component that I am modifying just before the PrintJob runs,
extends the UIComponent. I am going to take a wild guess and say that I
should listen for the UpdateComplete Event - as that should get
triggered if I perform a Resize correct?
Thanks for your ideas -

single threaded nature of AS processing is reliable. The main function
does not know in any sense, but the execution path is linear.
Processing simply does not return to the main function until the called
function(s) is/are complete.
This does not necessarily mean that the UI is done rendering. That
stuff is controlled bu the invalidation system. But code processing is
linear.
If your wife sends you shopping, she has no idea whether you went to the
bar while you were gone, but, assuming you have no bugs (or delegate the
shopping to someone else), when you return, the shopping is done.

Subject: RE: [flexcoders] Question on calling multiple Functions in
sequence
Thank you Tracy and Eric - this DOES help me a lot -
But I need to ask, what facilities are built into the FlashPlayer, that
guarantees that Function2 doesn't run until Function1 not only executes,
but actually FINISHES?
Doing computations is one thing, but when you are doing scaling
functions, or anything else that really doesn't provide any feedback one
way or another when it's actually finished (scaling an object in this
case), how can the containing function really KNOW?
I know these may be novice questions, but these types of issues have
been nagging me for a long time. The more I can understand what's
really going on under the hood, the more effective of a programmer I can
be.
Thank you again for all your comments - please keep them coming :)

When dealing with things inside the flash player - you need to deal with
it as if it was single threaded - because generally, it is. In your
example, the functions would be called in order, one after another...not
all at the same time as you may think so lets say you had an example
like this
var myNumber:Number = 0;
private function doThisFunction():void{
myFunction1();
myFunction2();
myFunction3();
}
if function 1 added 10 to myNumber, function 2 multiplied it by 5, and
function 3 subtracted 12 - it would happen in that order exactly - and
you can count on that - so your final result would be 38
hope this helps

Hello All,
I was wondering how things work, when calling multiple functions in
sequence. For example, in this function:
private function doThisFunction():void
{
myFunctionOne();
myFunctionTwo();
myFunctionThree();
}
When I execute doThisFunction, does it literally run the 3 functions
one-two-three, or does it execute the first function, waits for it to
finish, then runs the second function, waits for it to finish, then
finally runs the third function. How could doThisFunction possibly
know when myFunctionOne even finishes?
My end goal, is to create a way for a function (containing more
functions within) to stop and wait for each function to run
complete, before executing the next one. I know Events are used quite
often when things must happen in a sequence, but when it comes to things
like Scaling or Sizing a Component, how could I possibly know when
something like that finishes?
Thanks in advance for any advice you can all throw my way :)

[flexcoders] Component intercepting an event, preventing another control to receive it...
Hello All, I have a floating control, which contains a TextArea. This floating control, is a Child of my main Custom Control - which serves as the root interface for the entire application. On my main Custom Control, I have a MouseWheel event listener/function setup, which handles the scaling of all the content contained within that control. Overall, it works beautifully, but if the mouse cursor happens to be over a TextArea when the user Scrolls the MouseWheel, the Scaling Function attached to the MouseWheel event never triggers. Obviously, the TextArea Control has built-in listeners for MouseEvents - specifically for the MouseWheel, so that the Text can scroll when the user scrolls the MouseWheel. Even when the floating control is Disabled (which I thought disabled all it's children), the MouseWheel Events STILL don't trigger my Scaling Function. I looked at the default behavior of Mouse Events, and Bubbling is true by default. I'm not sure if this issue pertains to Event Bubbling or not, but I am really stuck right now, and could use some help - If any of you could throw some ideas my way, I'd be very appreciative. Thanks in advance, Mike
[flexcoders] Making dragProxyImage snap to mouse cursor when performing doDrag()
Hello All, I have an Icon Bar where users can drag Icons from a floating bar, and create duplicates on the map below. I have my image icons setup in such a way, where they all have an arrow on the upper left-hand corner, which visually indicates to the user, the 0,0 point. The problem I am having, is when the user starts dragging the icon, it starts dragging the icon immediately without any relation to the mouse cursor and it's related dragProxyImage. When the icon gets dropped onto the map, it gets offset - by the same amount of distance, as the mouse cursor distance from the registration point of the dragProxy Image. This could all be alleviated, if I could just force the dragProxyImage to snap it's 0,0 registration point, to the tip of the mouse cursor. This way, the Icon will appear on the map, precisely where the user wants to put it. Does anybody have any suggestions as to how I could accomplish something like this? Thanks in advance for all your help. Mike
[flexcoders] ContextMenu events NOT firing when mouse over certain components
Hello All, I have a Lake Map Application that I am converting from Flash to Flex, and am having some serious issues when it comes to Context Menus. I have a Box Container, which holds a custom MapViewer Component (based on the UIComponent), in addition to a background Canvas (which provides the ability to change the Lake Map's underlying background color). Keeping in mind that maps have an irregular shape - and are not perfect square in nature, as long as the Mouse Cursor is NOT over any Map Shapes, the Functions will trigger. On the other side of the coin, if the Mouse Cursor IS on top of anything Map Related, absolutely nothing happens. No matter where the Mouse Cursor is within the Box Container, the appropriate Context Menu DOES pop up. For the life of me, I can't figure out why my functions are not getting triggered whenever the mouse is over the Map Portions. If anybody could please provide any hints as to why this is happening, I would be absolutely grateful. Thank You in advance for your help, and have a wonderful Christmas :) Mike

[flexcoders] Help with Printing (relates to Scaling Object, just before sending printjob)
Greetings All! I have a major problem, where I have a function that properly scales an Object *just* before sending it to the printer. The issue is, the Object isn't scaling fast enough, so by the time it gets added to the PrintJob, it still isn't the proper scale - and looks completely wrong on the actual printout. Initially, I figured I could simply scale the Object first (in an entirely different function), then create some intentional pauses in the code (or use callLater in the right places), THEN run my PrintJob function code. BUT, my scaling functions rely on information brought back from the PrintJob - like PageWidth and PageHeight - which means, my Scaling Function must be called from within my PrintJob function. Bottom line, is that everything is happening too quickly, for the PrintJob to capture the properly scaled object. Is there a way for me to insert some intentional pauses, to slow things down, and give the object to be printed, time to properly scale, before getting sent to the PrintJob? Thank you in advance, for any help you can offer. Mike
[flexcoders] Controlling MenuBar Submenus via Code frustrations
Greetings All, I've burned an entire DAY searching the web for examples of how to control sub-menus in a MenuBar control, via code. The main types of things I need to accomplish, is toggling Checkboxes and Radio Buttons, when certain application variables change. My MenuBar has 6 primary menus across the top, and each primary menu, could have any number of additional sub-menus (which have several variations of menu types - Checkboxes, Radio Buttons, etc.) My MenuBar is being populated via an external XML File. Per the docs, each top level menu is considered a 'MenuBarItem', but there is very little helpful information after that. All the help docs focus primarily on listening for MenuBar events and writing functions to respond - but there is NOTHING on how to do the reverse. I consider myself to be a fairly seasoned Flex Programmer, but this MenuBar stuff has got me stumped, and quite frustrated. If anybody has any examples on this topic, I would be VERY grateful. Thanks in advance for any help, Mike

[flexcoders] Help! - certain portions of text disappear when printing from Flex App
Hello All, this is one of the most frustrating problems I think I ever had to deal with... Instead of creating an invisible container which properly lays out all my printable elements, I went and created a WYSIWYG mock-up of the final elements to be printed. This way, once the user is satisfied with what he/she sees on the screen, they can be confident that this will be what comes out on the printer. For ease of use, I placed my PrintControl inside of a drag able sizeable TitleWindow - so the user can Pan and Zoom the content around. With that said, I am experiencing some issues with my Text disappearing - specifically at certain Zoom Levels. And it's ALWAYS the last Word in a Sentence. I am not sure why this is happening, and why it only happens at certain Zoom Levels, but it's becoming increasingly frustrating for me and my users. Quick FYI, I am using the mx:Text/ control to display my text. I am considering using a different control, and rendering it all as HTML - so I don't have to create all these unique Styles, due to the text being so different in so many places. Just in case my problems had to do with Fonts, and any related issues that go along with Fonts, I went ahead and embedded all my Fonts as well as turning on the FlashType option. I have my Anti-Aliasing settings set to maximum, and I tried both Pixel and Sub-Pixel settings in hopes of that having a positive effect. In addition to this, I tried playing with all the FlexPrintJobScaleType settings in case that was messing with my text. Still, I get sporadic results - as well as getting different results on *different computers*. Could somebody please offer any words of wisdom as to why this may be happening?

[flexcoders] PNG transparencies no longer work, when printing as Vector

[flexcoders] Questions regarding printAsBitmap - true v.s. false
Hello All, This printer setting seems obvious enough, and have played with the settings pretty extensively - in order to compare my printer outputs side-by-side. The document in particular that I am trying to print, is primarily made up of high-res images, and then in the middle of all that, a DataGrid Control populated with 140 Rows. Now if I try to print the document as Vector, I lose all of my Drop Shadows - and the .png transparency no longer works. Wherever there is a Zero Alpha area on the .png, it shows up as Black on the printout. Furthermore, if I try to print the document as Bitmap, I get my Drop Shadows back as well as the transparencies, BUT the TEXT within the DataGrid is no longer all the sharp crisp. It's not bad, but it's absolutely beautiful when I print it all as Vector. Also, the Images too - are not as sharp as they were when printing as Vector. In fact, the document overall, loses a bit of quality, whenever I send it as a Bitmap. Could somebody shed some light on this topic, and indicate if there is a way for me to either get my .png transparencies to work when sending as a Vector, OR how to get my Fonts to be sharper, when sending as a Bitmap.

[flexcoders] Copying/Pasting from MS Word to a Rich Text Editor inside a Flex App
Hello All, Has there been any more headway made, regarding copying and pasting from a Word Document to a RTE within a Flex Application, and have the ability for the Flex App to decode all the MS Word Control Codes on the fly (and finally, having the document show up almost identical in the RTE). I know there are lots of different ways to render text - HTML, Rich Text Control Codes, and then the bulky MS Word Control Codes... This has been the biggest challenge I think, without having some other active control sitting in the middle, which handles all the decoding.

[flexcoders] Question on Ely's SuperImage Component
Hello All, I know there are lots of people using this, so I wanted to ask if this component can perform some functions that the standard Image Component can do.

I do this quite often, if I have an Image that is quite large - and has a lot of extraneous background stuff that I don't want to be displayed. With the Flex Image, I size place the container where I need it to be - then I move scale the Content around within the container - in order to show only the parts that I want. The SuperImage Component doesn't have a Content Property - so this leads me to believe, that I can't perform the same functions as the Image. Is this the right assumption to make?

What I was hoping to do, is set the Width and Height settings of the Image Component itself, and then set the ScaleX, ScaleY, X and Y Properties of the content. I was assuming that the Image Holder would Clip the Content, since Adobe made available to the Developer, Properties for the Image Control itself, in addition to Properties for the content in which the Control houses. Am I wrong in this thinking? In order to achieve my goals of showing only certain areas of the Image to be displayed, will I be forced to put each of my Images into a Box container?

[flexcoders] Need advice on which Method to Override inside DataGrid...

[flexcoders] Anybody experience Child Objects, exceeding the bounds of it's Parent Container?
Hello All, I posted about this a couple days ago, with no response whatsoever. Let me simplify the post, and ask once again: Has anybody had a Child Object (in my case, an external SWF 2200x2000 in size), spilling over beyond the extents of it's Parent Container (in this case, a TitleWindow)? Actually, here is the hierarchy of the Controls: TitleWindow Canvas UIComponent (with embedded SWF) I have a TitleWindow, with draggable content that sits within - this content is a Vector Lake Map, in which the user can Pan Zoom. The whole point of this, is that the Window can be moved to a place on the desktop, where it doesn't overlap any other content - but can remain open, as a reference to the user. This doesn't happen all the time, but at certain Zoom Levels. Instead of the Title Window cutting off the Map in the Lower Right-Hand corner (which is the normal behavior of any container), it allows the remainder of the Map to show - thus taking up the remaining lower-right extent of the Application Window. If I manually resize the TitleWindow, it immediately triggers the Content to be clipped - and everything looks fine. Once again, the Map ONLY spills over, from 0,0 of the Title Window and down to the Right. It's as if the TitleWindow isn't aware that the Content is larger than it's own size, and forgets to Clip everything starting at the lower Right-Hand corner, and beyond.

[flexcoders] Problem with Content spilling over beyond it's container's bounds
Hello All, I have an irritating problem with a draggable TitleWindow, that houses a UIComponent w/embedded SWF. My Custom Class extending a UIComponent embeds an external SWF File, which gives me the ability to wrap it with code. This way I can control the SWF and all the MovieClips it contains, programmatically. Basically, upon the initial Load of the UIComponent, it exceeds the size of the TitleWindow - and instead of the TitleWindow Container masking off the extents of the UIComponent, it literally lets the entire SWF File show through. Now if I trigger a Resize Event by actually sizing the TitleWindow (I have code in place, that allows the user to resize the window), THEN the TitleWindow immediately clips the Content properly. The UIComponent can be controlled by the User, via a Slider Control (which controls the Zoom Level), and the user can also pan the Component around via startDrag() and stopDrag(). Because of all this potential interaction, it's imperative that the Content's Parent Container, properly clips the parts that should not be showing. So with all that said, is there anything I can do differently, to ensure that the TitleWindow always clips the Children that it houses? Thanks in advance for your help, Mike
RE: [flexcoders] Can't we access MovieClips contained in embedded SWF's?
Hello Scott (in particular) :)
You mentioned a Proxy - what you do mean by this exactly?
Is this supposed to be some custom class that I write? If so, what is
supposed to be contained within it?
I did read up on the Document Object, and I am now doing my Flash 9 FLA
files with a custom Document Class, representing the Root Timeline. I
am pretty sure I did it right, since I am getting no compile errors.
But my question is, is the AS3 Class File I used for the Document
Object, strictly used for the FLA file? Or is this also used inside of
Flex Builder, after I bring the external SWF file in?
This is where I am getting a little confused.
All the articles I find on this topic, covers the Flash side of things -
and they never take that next step, and tell you how to reference it
inside of Flex.
If you have anything else on this topic, I'd really be grateful for your
help.
Thanks,
Mike

If you are using Flash 9, you can use a document class (I believe) at
the root level and have Flex reference it by that. Your document class
would set up an API, so you don't have to peer into the movie itself.
Basically a proxy. Sorry I don't have the implementation in front of me,
but I believe it's possible.
So, if previous code was correct, could do something like:
var platProxy:YourProxy = platObject.getChildByName('instancename') as
YourProxy
platProxy.hideAll();
platProxy.showByID( {id:'plat_xxx'} );
Just an idea!

RE: [flexcoders] Can't we access MovieClips contained in embedded SWF's?
Hey guys, Thanks for the initial help on this - I finally got this to work, at 3am this morning! Just a quick note to anybody else reading this: For this FP9, AS3 SWF thing to work properly, you must use the SWFLoader.load Command. I was using a method I saw in a Cairngorm App, where you would bring in all the Assets using the Embed Metatag, and then casting them as a Class. This royally screws things up, and I can only assume that it's because of the Class casting. So after changing my method to Load, instead of setting the Source property to an already embedded Asset, I could finally gain access to my named MovieClips defined within the SWF File. Now my next question: Can I traverse the Document Tree, using the Dot Notation - if there are more MovieClips, embedded within the MovieClips I created variables for (using the getChild?

There are 4 other possible Statuses, that the Lot could have - and each Status is represented by a unique color. After the Plat SWF is brought in, the Flex App will loop through all 140 Lots, and set each corresponding MovieClip color, in addition to any other information I want shown. Luckily, in this particular case, I will have knowledge beforehand based on the database data, as to which Lots will already pre-exist on the SWF. This is where I need to decide, which parts I should code within the Flash 9 SWF, and which parts I should code within Flex. If I had my choice of course, I'd code everything 100% within Flex. Bottom line, I just want to code the bare minimum on the SWF side, so I can programmatically control everything from within Flex. Anyway, moving on, when the mouse hovers over a Lot, I need to have some additional information popup - like a ToolTip. I need the dimensions, total square footage, and the customer information (if the Lot has been sold).

RE: [flexcoders] Can't we access MovieClips contained in embedded SWF's?
A, wonderful!
Okay, with all that said, if I create a custom class, extending lets say
a MovieClip, in any other situation I would have to declare all of my
MovieClips contained within the main Movie, as Public Variables if I
hoped to control them programmatically correct? You know, just like
creating custom classes within Flex, and in order to access the Controls
residing in the MXML file, you have to create Public Variables with the
same names, and cast them as their proper types (i.e.. Button, Slider,
TitleWindow, etc.) If I am wrong on this, could you correct me? :-)
And if so, it would be because of all these declared Variables, that
would cause them to be exposed allow me to access them from within
Flex correct?
Since we are using AS3 across the board, will Flex then have native
access to all the Objects contained within the SWF File?
What I'd love to do, is use Flex Effects and Transitions to control how
the MovieClips that reside on the SWF, behave and interact in the main
application.
In the meantime, I will read up as much as I can on this topic - thanks
again for pointing me in the right direction.

Cool new feature of Flash Professional 9 ActionScript 3 Preview:
Document Class.
Install Flash 9 Preview, create a new document, and in the
Properties Panel, you'll see a new field, Document Class. You can
enter the name of an AS3 class here, as long as it's in your class path,
and it will serve as the main class of your swf. The class you uses must
extend MovieClip or Sprite (or something else that extends one of
those).

also:
http://www.google.com/search?q=flash+9+document+classie=utf-8oe=utf-8;
rls=org.mozilla:en-US:officialclient=firefox-a
Very easy to set up. From Flash 9:
New document - File -Publish Settings - Flash (tab) - AS version -
Settings (button) - Document Class: Enter full class definition (w
package) pointing to your class that extends Sprite or MovieClip (i
believe).
This class becomes your main interface to movie.

How can I access properties execute functions that are embedded in the SWF Files, from within Flex?

Must I use the LocalConnection method, in order to simply speak to my Embedded SWF Files? Or is there a more direct approach? Just for a quick example, I was hoping to use something to this effect: mySWFLoader.content.gotoAndPlay(10); Well, you get the idea... Any suggestions, would be greatly appreciated. Mike

[flexcoders] What's the official consensus of using CodeBehind??
Hello All, Could some of you more savvy coders, please take a moment of your valuable time and throw some words of wisdom out there regarding CodeBehind? Since I love using Packages and Classes, it feels very natural for me to use this method. BUT, based on where things are going with Flex, is this considered to be a good programming practice? I would love to know sooner versus later, so that I don't have to back and redo a bunch of coding. I am a REAL stickler when it comes to good coding practices.

[flexcoders] StartDrag() versus DragManager.doDrag()
Hello All, I am getting confused, as to which method I should use, for simply panning around an Image/SWF file. I did follow Michael's suggestions, and looked at the quick Dragging an Image to Canvas tutorial contained in the help files. My understanding is a little deeper, when it comes to using DragManager - but in my case, I am getting some odd results. For the purposes of strictly panning Objects around, startDrag() is providing me better Visual Results - as it happens in real-time when dragging the mouse around. When using doDrag(), it makes a copy of the Object (I suppose, it's the Proxy being dragged) and then finishes the move, upon the mouse release. Also, for some reason, when using doDrag(), the Object doesn't always move the same distance, when compared to the distance of the mouse drag. Really weird... And it gets worse, the more distance I move the mouse. One last thing too, the ImageProxy appears Outside of the container, when dragging the Image - and in my case, my SWF File is 2,000 x 2,200 - so you can imagine the whole screen filling up with my Image. Since I am not doing any advanced functions, and just want to move the Image around on the Screen, would it be acceptable to use startDrag()? I guess what I REALLY need to find out, is if startDrag() and stopDrag() will eventually be deprecated, or be considered NOT the way to handle dragging Objects around. Could any of you shed some additional light on this topic? Thanks in advance, Mike
[flexcoders] Registration Points and Flex -
Hello All, As all of you Flash People know, whenever you have Assets in your Library, they all have a Registration Point. I know 99% of you already know this, but for those who don't, the Registration Point is the spot on the Object, that is considered to be 0,0. Typically, it's either in the upper-left-hand corner, or smack-dab in the middle. This way, whenever you are Scaling your Object, the sizing will get bigger downwards and to the right, or it will scale evenly from the Center Out. With this said, after embedding all my Graphical Icons (which will serve as WayPoints for my Map Application), how can I control the nature of how these Icons Scale?? Some of my Icons, are drawn in such a way, where they have a little arrow in the upper-left-hand corner. That way, it's obvious to the user, that wherever they drop their WayPoint on the Map, the top of the Pointer on the Icon, IS precisely the spot where the WayPoint coordinates are referring to (and will scale accordingly from that point). Then again, some of my other Icons, are just general in nature, and those need to specifically scale from the CENTER Out. In Flash, I was able to tweak the Registration Points, so that they would automatically Scale the way I needed them to. BUT, in Flex, I don't even know where to start with something like this. Could anybody shed some light on this topic for me? Thanks in advance, Mike
RE: [flexcoders] What's the official consensus of using CodeBehind??
YES, all these points you bring up in your post, are the things flying through my mind. It's like having to maintain twice as many files, just for the purpose of creating a clean separation of the two. This is why I am torn, and wanted to ask everybody else. I was fortunate enough to be introduced to Cairngorm from the very beginning, and as painful as it was, wrapping my head around it while learning Flex too, I am SO happy that I did it. So, I want to make sure I do the same thing with CodeBehind - because it really would mean a huge task of recoding applications. I just need to know for what? Peace of mind? Well, maybe :) Thanks everybody for contributing to this thread - and I know this was just discussed not too long ago, but the end result really didn't lean one way or another.

What is your reasoning to use code behind? Why would you want to double every class and add an additional inheritance layer just to separate Mxml from ActionScript? Why would you want to declare every component you are using twice, once in AS and the second time in Mxml? Is it to separate presentation from functionality? Generally this is a good idea, but i think it is important where to draw the line between the two. When you think of traditional systems with a template engine as the presentation layer, the templates also contain some code to build the presentation, while the functionality is implemented by plain classes. Now if we translate this thinking to Mxml and ActionScript, we should leave all the code we need to build the presentation inside the Mxml files and factor out the real functionality into classes. So i'd say, there is nothing wrong with ActionScript in Mxml files as long as it is strictly presenation related. Cheers Ralf.

[flexcoders] Image versus SWFLoader for loading external SWF Files
Hello All, If I want to bring in an external SWF File, and this SWF File doesn't contain anything else other than pure Vector Information making up a map graphic, is there a real need to use SWFLoader? I mean, the true purpose of using SWFLoader to bring in SWF Files, is to gain access to any advanced aspects of the SWF - like Named Assets, Functions, the PlayHead in cases of a multi-framed SWF, etc. If this is the only reason, then using the SWFLoader would be overkill to bring in something that the Image could easily take care of correct?

RE: [flexcoders] Re: Can drag-able content within a container, update it's Scrollbars?
Yes, this is exactly what I was thinking... The benefits are, it's impossible to drag the content off the screen, as you are ultimately remote controlling the scrollbars to handle the movement of the content. It just looks like you are using the mouse to pan things around. So what you are both saying then, is I should just listen for the Mouse Movements, and have it update the Horizontal Vertical Scrollbars? I don't have much experience, messing around with Scrollbars and their associated values. Is it as simple as listening for the changes in X,Y - and if there are changes in the X axis, then trigger a function to change the Horizontal Scroll? And then in the Y, change the Vertical? This topic is very interesting to me, and I'd love to hear more on how to accomplish something like this.

If it's really a matter of scrolling a container that has scrollbars by dragging the contents, I would use a mouselistener (as mike suggested) that would update the verticalScrollPosition and horizontalScrollPosition of the parent container. You wouldn't actually be moving the inner stuff at all. You would sort of be faking the dragging. Why do it like this? 1. dragging too far one way or the other wouldn't drag the inner components out of the viewable area, 2. if you actually wanted to use the scrollbars as well then they would still work (and they would update correctly as you're dragging) Just my two cents.

Hello Michael! You hit the nail right on the head - this is exactly what I am looking for. In fact, this scenario closely resembles how I wrote my existing version with Flash. I will scour your post a few times over, and research every aspect of it - then hopefully I will be able to put together a game plan in my head, on how to start the conversion process. The cool part too, is that I can port most of my AS 2.0 code over, as it relates to all the GPS Conversion logic, and all other math logic / coordinate conversion functions that I had to slave countless hours over figuring out.

Once you have this base set up, set your tool bar - drag off the tool bar, create a dragData object with a new instance of the said icon, - user drops icon onto MapViewer - MapViewer konws how to accept dragDrop, then processes the x,y position converts coords, takes that new instance you created from the tool bar factory and addChild() into the MapAssets component precisely where the user dropped it. Now that the icon is perfectly placed INSIDE the MapAssets instance as the user pans the map around, them icon follows because the MapViewer is positioning the MapLoader along with the MapViewer.

[flexcoders] Can Flex directly replace Flash????
Hello All, As I dive into converting my commercial Flash Map Application, into a Flex-based Application, I am quickly finding out that Flex may not be able to perform some key functions. This of course, may be attributed to my lack of understanding of Flex - so my main goal of this post, is to get some clarifications from the List Gurus regarding if/how I can do the same things in Flex, as I did in Flash. For a quick overview, I wrote a Commercial Flash Application for my primary client, and it allows their user-base to load Vector-based Lake Maps, from their 10,000+ Lake Map Database. Once the user browses to the desired map, they can immediately start to customize it - by adding Waypoint Icons, Points of Interest, Notes, etc. As they move their mouse cursor around, they get real-time GPS Coordinates in any format they like. On the Flash programming side of things, I used the following methodology: I use CF / Remoting to handle all Database reads/writes. I use the MovieClipLoader Component, to handle all the loading of SWF Maps. I have an Icon Bar at the bottom of the screen, in which the user can drag those Icons directly onto the Map. After they release the Mouse Button, I use attachMovie() to attach a copy of the Icon to the Map SWF File. At the same time, I make a Remoting call, to record the x,y coordinates of the Icon in relation to the Map. When the user wants to come back to their custom map in the future, I simply make another Remoting Call to the CF Server, get the Results, and then Loop through the Result Set. Within the For/Next Loop, I again use attachMovie() to put the Icons back to their original locations when they were first saved. This pretty much covers the logic required, to make my Map Application do it's thing. Now how the heck would I duplicate this functionality inside of Flex??? So far, I've mastered the SWFLoader Component, and can Scale/Zoom the SWF Files, in addition to Panning them around using startDrag() and stopDrag(). This is where things pretty much stop, as I am not sure what to do next. The Remoting stuff is a total no-brainer, and I am well-versed in Cairngorm-based Flex Apps - so I have the Data interaction aspects down cold. What I need the most, is how to handle all the Drag/Drop logic with the Icons, and attaching them to the Map SWF File (so that when I pan the SWFLoader Component around, the Icons go right along with it). Sorry for the lengthy post, but I needed to explain things as clearly as possible to get my problems across. Thanks in advance, for any help you can throw my way, Mike
[flexcoders] SWFLoader Questions - need help from the gurus!
Hello All, I am getting confused, as to when I should be referencing the SWFLoader Component ITSELF, versus the SWFLoader.content - as it relates to modifying it's properties, etc. For example, the SWFLoader has the scaleX and scaleY properties available to the developer. BUT, so does the Content - So, if I wanted to Zoom in/out my SWFLoader Content, what would be the more appropriate command? 1) SWFLoader.scaleX = value; -or- 2) SWFLoader.content.scaleX = value; This is something, that has always confused me. Also, as many Properties and Methods that the SWFLoader SWFLoader.content have in common, there are some that are unique only to themselves. For example, if I want to make the content draggable, the only portion that makes startDrag() and stopDrag() available to the developer, is the SWFLoader - NOT the SWFLoader.content - I guess, what I am asking here, is what's the general rule of thumb - when attempting to Scale, Move, ... the contents of the SWFLoader? The SWFLoader itself? Or the SWFLoader.content? Thanks SO much in advance, for anything you can offer regarding this. Mike

[flexcoders] Collection_Change type Event for a ValueObject??
Hello all, I am trying to create a Form that can sense when a change in the Data has been made. My Form is comprised mainly of TextInputs, in addition to a few other types of controls. Every single control's DataProvider is tied to the same ValueObject - and I want to trigger a local dataChanged:Boolean variable, so I can prompt the user to save their changes if they want to close the Form before saving. This is easy enough with the ArrayCollection, as the Collection_Change Event takes care of this. But how about a ValueObject? I know I could tie an Event Listener to each TextInput residing on the Control, and broadcast a Change Event there, but that seems a tad overkill. It would seem more logical, to tie some type of Listener to the ValueObject itself, but I don't think there is anything inherently built into this generic class, that provides for this functionality. Any ideas would be greatly appreciated :) Thanks, Mike
RE: [flexcoders] BindingUtils.bindProperty versus mx:Binding
So with that said, is it safe to say that using the bindProperty method in AS, DOES release the memory it uses whenever the control gets destroyed?

It's in these PopUp Windows, where I have to create all these bindings, so that the ValueObjects which reside in the Model, get properly updated when the user changes the information. This is an interesting subject, and I hope it gets discussed further :) Thanks everybody so far, for all your help and insights.

RE: [flexcoders] Need primer on Events, from the List Gurus -
Thank you Dimitrios!
Now it all makes sense to me - the key is using the Getters and Setters as the
method for handling all the value assignments. Once you do that, you have all
the CollectionEvents at your disposal.
So I guess in some odd way, we are still using Event Broadcasting to accomplish
my goals, but just not in the way that I envisioned doing it.
Very nice :)

Ok here is how I would do it. Say the ArrayCollection held notes as an example.

bla:MYView notes={ModelLocator.getInstance().notes}/
// inside the view
public function set notes( values:ArrayCollection ):void {

Now what will happen is the minute you add a new note to your model, the
onCollectionChange method will be called and that will allow you to do any
added operations you wish, hope that helps.

Hello Dimitrios,
I was trying to keep my post as generic as possible - which is why I didn't
post specifics.
In this particular instance however, I want to broadcast a Custom Event to a
DataGrid residing on a Panel Control - to Scroll to the very top, whenever I
add a new record to an ArrayCollection (residing in the ModelLocater). This
can happen ONLY when I add a new record - and this is why I want to create a
Custom Event for this. I am pushing for a Custom Event, because I don't think
there is a built-in Event native to the DataGrid, that I can count on 100% of
the time, to fire off ONLY when New Records are being added.
The catch is, I can't dispatch the Event until I get my onResult response from
the ColdFusion Server - indicating that the Database Insert was in fact
successful, and that it's now okay to update the Model's ArrayCollection with
the new ValueObject.
Since the onResult logic resides in a Cairngorm Command Class, this is where I
need to dispatch the Event from. Or at least initiate the command to dispatch
the Event, which can reside in the ModelLocater - and dispatch it from there.
Since all of my primary Views containing the Model-bound Controls, have a
reference to the ModelLocater, I am thinking that there must be a way to
dispatch these Events from the Model - and have a way for these Views to
respond accordingly.
If you could help me out in this regard, I really would be truly grateful. My
application development, has literally come to a screeching HALT, because of me
not knowing how to handle all these issues.
I am tracking down every Event Broadcaster and Listener Tutorial I can get my
hands on, so that I can learn more about how all this works. But in all of the
examples I download and dissect, they ALL have a common View, that centralizes
the code - in which it's quite easy to tie everything together.
In my case, I have Views and Controls scattered all over the place - and they
can be instantiated (or not be for that matter) at any given moment. I just
don't know how to write code to broadcast Events in such a manner, so that each
component has no prior knowledge of any other component.
I hope I'm explaining all this properly...

Thanks Alex!
With the help of Dimitrios, I was able to accomplish what I needed to.
Still, using your cool little utility Class, it makes it really easy for
somebody to listen for very particular changes in a variable.
Since I am using Cairngorm, and the nature of Cairngorm centralizes
everything in the Model, I was trying to Dispatch Custom Events, from my
Commands (and failing miserably).
Using the method I just learned (getters, setters, and events), this way
is much cleaner.

Class File
Hi Mike,
Observe and ObserveValue have been designed to work with MXML binding
only. The curly braces in the source and handler properties are being
treated differently by the MXML compiler than just simple ActionScript
assingments as you do in your example. Therefore, the current
implementation relies on the MXML compiler and cannot be used in
ActionScript.
However, I'd be intersted in why you want to use data binding in an
ActionScript environment (for your ActionScript model or utility
classes). In my experience, using a pure EventDispatcher is easier to
write and most importantly to read (especially for other developer,
potentially coming from other technologies). Just let your class
dispatch a custom event when something important happens. Or if you
cannot do that easily, listen to the propertyChange event of Bindable
properties.
Best,
Alex

In my real code, I wait for the Creation Complete Event, before I
initialize all of my Event Listeners, etc. So you can assume that my
real code, is properly setup.
My real question here is, when creating component written purely in
AS3, can they be used either way - like as an inline Component in

why not, since MXML Controls are all just Class Files anyway...
So I just wanted to know if somebody could shed some light on what I'm

be executed when that event is triggered. The component must know about the event structure. The component that dispatches the event must also know the event structure. The event becomes an API, so to speak. Any component can listen or dispatch to that api. In other words, the event itself is communication between the two components and both components must know how to speak and listen to the event. --- On Fri, 12 Jan 2007 12:53:14 -0600, Mike Anderson wrote: Hello All, This thread, directly relates to all the other ones I've posted recently - as I think one of my root problems, is truly understanding on how Events get propagated within an application.

[flexcoders] Need advice on which Event I should be using -
Hello All, I have a Cairngorm application containing a DataGrid, in which the Grid's dataProvider is bound to an ArrayCollection (comprised of ValueObjects) located in the ApplicationModel. Whenever I want to add a new record to the dataProvider, I first create a new ValueObject instance, then populate it using a Details Form. Of course, being a Cairngorm-based app, I dispatch a Cairngorm Event containing the ValueObject (which causes it to be sent off to the server), and then wait for the onResult response from the server. Obviously, I can't go blindly adding the new Record to the dataProvider, until I know for sure that I get a valid onResult response from the server. Now assuming that I DO get my onResult event, what I do then is add the ValueObject to the model's ArrayCollection using the addItemAt() method, inserting the ValueObject at Index Zero so it gets pushed to the top. This way, all newly created records appear at the top of the DataGrid (which is exactly what I want to happen). This is where things get fuzzy... Which Event should I have the DataGrid listen to, so that it gets scrolled to the very top, *ONLY* when a new record gets added to it's dataProvider? This is a case, where I'd actually prefer dispatching a Custom Event, so that I can manually dispatch it from the same Cairngorm Command Class handling the onResult Event - but I don't know if that is possible. I don't know yet, if I can dispatch events which get broadcasted across multiple controls. This is where I have a lot to learn, regarding the Event Model... If any of you could help me with this, I'd be very grateful for your help. Thanks in advance for everything, Mike
[flexcoders] Dispatching an Event from a Class
Hello All, I am attempting to dispatch an Event from a generic Class File, and I guess I'm not doing it correctly. I was hoping, that I could simply do this: import mx.events.IEventDispatcher And then in my function, I could simply dispatch the event like this: IEventDispatcher.dispatchEvent( event ); But it doesn't allow me to do this. In the meantime, I extended my Class to use the UIComponent, which automatically pulls in all the EventDispatcher stuff. Of course, it's silly for me to do this, since I really don't have a need to extend the UIComponent class. There must be a way, to import the proper Class, in order to simply dispatch events. Any advice? Thanks in advance for your help, Mike
RE: [flexcoders] Dispatching an Event from a Class
Yes, I understand this -
But what about a generic class, that does NOT extend any other classes
(which have the IEventDispatcher as part of their makeup)
In my generic class (in this case, my ModelLocater which is part of a
Cairngorm-based application), it doesn't natively have anything in there
which includes the EventDispatcher stuff.
So, I wanted to see what the bare minimum requirements would be, in
order to Dispatch an Event from a Class File that doesn't extend or
implement anything else.
Also, I DO have the [Bindable] Metatag on this class, and even know I
don't get any code-hinting whenever I type any dispatchEvent type
code, I don't get any Compiler Errors either... That struck me as odd,
but with what Tracy just mentioned, it does answer a few questions...
So I guess, the [Bindable] Metatag is a quick way to add this
functionality, but I am just curious if I wanted to accomplish this via
some other means.
Thanks for the info on this topic :)

Just call dispatchEvent() (e. g. dispatchEvent(new Event(Event.CHANGE)))

is held here - and I have a floating Debug Window which stays open
during the development phase of my application. In my Debug Popup
Window, I simply have a TextArea Control, in which I bind the
model.debugText variable to. Then whenever I want to perform a trace, I
just run my model.updateDebug() function, which in turn, appends any
new Debug Information, to the model.debugText variable. And voila! my
Debug Window gets updated with the debugText.
#3) Any time Text is added to a TextArea control, and the text size
exceeds the currently displayed limit, ScrollBars appear - and any
additional text added, gets placed below the visible area. With the
nature of the Text being debugging information, I am most interested in
ONLY the latest text being added - so I need to automatically scroll my
TextArea all the way to the bottom. I want within my grasp, the ability
to manually dispatch the event, which causes my TextInput Control to
scroll all the way to the bottom.
#4) I know that I could simply create an event listener for the TextArea
residing in my DebugWindow, that any time a change event occurs, to
run a function that causes the ScrollBars to move all the way to the
bottom.
So with all that said, I guess bottom line, I am asking this:
How can I write BOTH, and Event listener to listen for events, and ALSO
an Event Dispatcher to dispatch the event, whereas I can ANYWHERE inside
of my application, trigger this to happen any time I like??
I was under the impression, that Events get broadcasted Application
Wide - and that anything with an active listener running, will capture
and respond to the event. I guess I was sadly mistaken, because I am
hitting a MAJOR brick with all of this.
I would love to hear more input on this topic :)
Thanks,
Mike

Mike, I'm interested in why you would dispatch an Event from your
modelLocator? Could you please share?
Also, could this be a case where the Observe tag could help you?

Yes, I understand this -
But what about a generic class, that does NOT extend any other

In my generic class (in this case, my ModelLocater which is part
of a Cairngorm-based application), it doesn't natively have anything in
there which includes the EventDispatcher stuff.
So, I wanted to see what the bare minimum requirements would be,
in order to Dispatch an Event from a Class File that doesn't extend or
implement anything else.
Also, I DO have the [Bindable] Metatag on this class, and even
know I don't get any code-hinting whenever I type any dispatchEvent
type code, I don't get any Compiler Errors either... That struck me as
odd, but with what Tracy just mentioned, it does answer a few
questions...
So I guess, the [Bindable] Metatag is a quick way to add this
functionality, but I am just curious if I wanted to accomplish this via
some other means.
Thanks for the info on this topic :)

Just call dispatchEvent() (e. g. dispatchEvent(new
Event(Event.CHANGE))) in any class that implements IEventDispatcher (e.
g. all the EventDispatcher successors). Note, that UIComponent and all
its successors implement IEventDispatcher, so dispatchEvent() could be
called in any subclass of Box, ComboBox, Label, TextArea, HSlider, etc:
package {
import mx.controls.HSlider;
public class MyHSlider extends HSlider {
public function MyHSlider() {
super();
dispatchEvent(new Event(instanceConstructed));
}

Thanks Clint, for those links - The first link, has a section which explains the invalidation stuff - which was really informative. I love reading stuff like this, as it really gives better insight into how things work, as well as what's going through the minds of the Flex engineers, while designing their control's structure.

RE: [flexcoders] Need some direction from the Pros, on Event Dispatching, and Scoping issues
Too funny Clint - you read my mind on BOTH instances.
I first said to myself, that was Flash 8 Flex 1.5 Syntax (as I found
the Flex 2.0 syntax, since my original post last night)
And secondly, I also came to the conclusion, that dispatching an Event
manually may be overkill, since using a built-in Event and attaching a
function to it, will be all I really need for this particular
application.
Per another post, it was mentioned that I should use the
UpdateComplete event to cause the text to scroll to the bottom - but I
am finding out that this event gets triggered MUCH more often then
people may realize. Especially the resize event, in which I use quite a
bit with this TitleWindow...
For now I am using Change, and this should hopefully be all I need in
order to keep the most recently added text, visible in the control.
Again, Thanks for all your help - in addition to everybody else on this
list.
Take Care,
Mike

Oops that was Flex 1.5 syntax... should be.
traceArea.verticalScrollPosition = traceArea.maxVerticalScrollPosition;
It may even be possible to bind it.
mx:TextArea id=traceArea verticalScrollPosition={
traceArea.maxVerticalScrollPosition} /
I understand you want to dispatch a custom event here but it seems like
a bit overkill.

RE: [flexcoders] Re: Can controls be placed in the Title Area on TitleWindows and Panels??
Naw, you have a pretty good idea of what I mean. The thing is though, I am not complaining about the (lets say in this case) grey area which comprises the title bar going across the entire way. See, I want to keep that portion, as well as the height of it - but I just want to be able to put controls in there - as it gives the user the impression that the control is part of a different area on the screen. Sort of a background for the control - which sets it apart even more. I guess I could do what you mentioned, and create a container that mimics the exact look as the title bar, and place it directly beneath it - giving the illusion that the entire thing is one contiguous piece of real-estate. Still, I just wanted to know if Adobe provided any built-in methods, for doing something like this. Sort of like a TitleBar Renderer, or Skin perhaps - that can be dropped in using standard coding techniques. Now that I explained it further, hopefully that clarifies things where more people can jump in and provide extra input. Thanks for everything so far though - I really appreciate it.

[flexcoders] What happened to mx.utils.Delegate?
Is this now gone?
I am trying to add an EventListener to a Control that doesn't reside
locally to the main application. With that said, I need to use the
Delegate Class in order to specify the proper scope.
In Flex 1.5 as well as Flash, I would have coded my function similar to
this:
private function addEventListener():void
{
myControl.addEventListener(change,
mx.utils.Delegate.create(this, onControlChange));
}
private function onControlChange( event:Event ):void
{
// Change code goes here
}
Of course, the compiler knows nothing of the Delegate class and I get a
compile error -
This question also relates to my previous post, and I am hitting a major
brick wall with this scoping stuff. I had this down to a science with
all the Flash Applications I wrote in the past... I am getting a tad
frustrated, trying to port all my AS 2.0 code, to the new Flex
environment. Even Flex 1.5 had the Delegate Class - so Flex 2.0 must
have done away with it??? If so, how am I supposed to scope my
functions???
Thanks in advance for all your help,
Mike
RE: [flexcoders] What happened to mx.utils.Delegate?
Thanks Greg!
I actually just found this myself a few minutes before your reply, but
thanks for your effort nevertheless.
The Flex way is much easier and better to use, than Flash - it just
takes a little getting used to.

Mike,
I can not say for certain if the following will be of assistance.
However, based on your very concise description, it appears to
corroborate what you have observed.
The following is from page 16 in the PDF document Migrating
Applications to Flex 2:
Step 4: Update events
The Event model changed in Flex 2. However, you can migrate most event
handlers with
minimal effort. This section describes the most popular changes that you
must make to your
event handling code.
...
Remove delegates
You are no longer required to wrap a listener function with a Delegate
to maintain application
scope. You can remove the Delegate from the following line:
b1.addEventListener(click, mx.utils.Delegate.create(this,myListener));
So the line appears as follows:
b1.addEventListener(MouseEvent.CLICK, myListener);
I personally have found portions of the Migrating Applications to Flex
2 critically important. For reasons I do not know, this critical doc
is available as PDF only. Personally I would like to see this doc
included in the HTML browsable versions of the documents, and especially
up on LiveDocs where search engines could index it. That all said, the
direct link for downloading the PDF version is:
http://www.adobe.com/go/flex2_migrating_pdf
I just pulled the download link from the main Flex 2 Documentation page

[flexcoders] Can controls be placed in the Title Area on TitleWindows and Panels??
Hello All, I have an extreme need, to place some simple controls - where the Title normally appears within a Panel or TitleWindow. To further clarify, the top area where the x would appear, if you had the close button visible (in the case of a TitleWindow). I know that these are containers, and all the controls they contain, typically would appear within the display area - but when space is super tight, it's a terrible waste to not use that beautiful blank space that appears all the way across the top. And in some cases, it would actually look more appropriate - like in my particular case, a DataGrid appearing in the main display area - and a Search TextInput, in the blank space above (that I am referring to in this post). Is this possible? Thanks in advance for any information offered on this topic, Mike
