[flexcoders] Help trying to create a slightly complex border.
I'm trying to create a postage stamp like border - which would look like a border of overlapping circles - and am having issues. I want a constant fill and line/stroke style for all elements of my border. I was using degrafa to do this using circles and repeaters but couldn't get a single stroke around the edge of all the circles - so I thought I'd do it directly in AS3 to see if that was faster, however I have the following problems. First I tried doing it using circles, if I try setting the fill and line styles and then doing circles I get: - Blank gaps in the fill where the circles overlap - can I (and if so how do I tell it to) combine these circles into a single shape? - A border around each individual circle - rather than the shape as a whole. So I figured I was doing it wrong and took a look at curveTo() and drawPath() to try and draw a single object - but didn't have much luck with those either as I found it difficult to figure out how to use these for my desired result. The variables I'm working with is radius, circleOffset (the amount each circle is offset from the previous one), xCircles and yCircles (the calculated number of circles for the top bottom and left right respectively). Any help would be greatly appreciated.
[flexcoders] Getting progress of a POST operation (HTTPService or any other way)?
Is it possible to get the progress (or at least bytes sent) for a POST operation in any way, I'm currently using HTTPService but will happily change to something else if it will give me the ability to track the progress of the POST.
[flexcoders] Finding size of a DropShadowFilter (or other BitmapFilters)
I'm trying to determine the width of pixels that the DropShadowFilter is adding to my component when I'm trying to save the BitmapData (including the drop shadow) - is there some easy to get that or would I have to calculate it myself based on the filters settings (angle, blur, etc.)
[flexcoders] Issues trying to create a custom image component
I'm trying to create a custom image component so that I can have it with a border and rounded corners. I tried doing it by just extending the image component, but quickly found that it was a bit more difficult than I expected within the image component - as I couldn't figure out how to move the image itself around when drawing the border. So the second solution I came up with was as follows: * A custom component which has a child as the image * The image has a mask applied * The border is drawn using the custom components graphics This all works out pretty much OK, except for two issues: 1) The child image is only ever displayed if the custom component extends the Canvas component. 2) Resizing of the component does not work in the same way as resizing an image component - e.g. if you set a width on an image component then the image is scaled appropriately. With me extending the Canvas I just get scroll bars. The code for the component can be found here on pastie: http://pastie.org/326072 Any ideas are greatly appreciated.
[flexcoders] Re: Issues trying to create a custom image component
I've just this to updateDisplayList:
if(image) {
image.scaleX = this.scaleX;
image.scaleY = this.scaleY;
image.scrollRect = this.scrollRect;
}
It means I have to manually scale the thing using scaleX scaleY
rather than using maxWidth maxHeight, but it is more in line with
how I wanted it to work.
[flexcoders] Runtime exception handling, what's your method?
I'm about to embark on my third real Flex app and something I'm still not happy with is my handling (or lack of) of run time exceptions. Previously I've setup a logging target to log to the backend any strange/very rare exceptions that I can think of within my code. However the lack of a catch-all solution for those totally un-expected exceptions (which sneak through but are of course the worst kind) is something that I really miss from my previous (non Flex/flash) projects where I've had the ability to have a catch-all solution to wrap the entire application. I just wondered how other people were handling this, if at all? As no-one likes it when an error occurs and you don't know about it without someone telling you about it -- it's even worse if it kills the app.
[flexcoders] Re: Repeater items with two states and dataProvider binding resetting state
One thing that can help in this kind of situation is not to bind, but to explicitly set the dataProvider. Won't that also cause the repeater to refresh, or are you saying to find the child of the repeater and set its data to the data that is updated? This is what I was thinking of trying but I assumed I'd get the same issue.
[flexcoders] Repeater items with two states and dataProvider binding resetting state
I have a Repeater which is repeating an item with two states (an open state and a closed state), when I open one one of the items I then load some extra data in. When the extra data is loaded the item in the data provider (an array collection) is replaced - that way everything is updated via the bindings. The problem I have is that when the array collection binding fires the Repeater recreates/refreshes each of the items so any that were open close, which is, of course, not what I want. I'll probably have to code this all up myself without using the Repeater, but I wondered if anyone else had any thoughts before I start down that path.

[flexcoders] Re: Custom Cursors causing slowdown
Just getting back to this, would you recommend upping the framerate on the application then or just put up with the slow cursors. I'm just conscious that upping the framerate will up the CPU usage slightly with Flex but I haven't seen much research into how much difference it will make. --- In flexcoders@yahoogroups.com, Troy Gilbert [EMAIL PROTECTED] wrote: I wondered if anyone else had experienced similar issues? What you're seeing is your app's actual framerate. Nothing is going slower. Here's why... If you don't specify any custom cursors, Flash just uses the OS's cursor and let's the OS do its standard thing of drawing it (which all modern OS's do as a very high priority process, usually part of the video driver, so that the mouse is always responsive). When you specify a custom cursor, the Flash Player actually does something tricky (some may say hacky!).

Personally, I think Adobe should provide a cursor API that's implemented as a native OS cursor (provide a bitmap of a fixed resolution, for example). At a minimum, I think the Flash Player should expose a collection of native cursors that map to the browser's native cursors.

[flexcoders] Get actual size of a canvas (the internal size)
I know I've done this before, but I can't remember where and trawling through the documentation isn't helping me. Basically I want to add something to a Canvas that is a 100% of it's internal size - so as the Canvas grows to add children (as scrolling is enabled) I want my child to still be 100% the size of the Canvas' internal area. If I set it's percentWidth percentHeight to 100 then it just sizes up to the displayed portion of the canvas, same goes for the unscaledWidth unscaledHeight values passed to updateDisplayList() they appear to be the visible dimensions of the Canvas. What I need is the width + it's scroll, so that's why I'm calling it the internal size of the Canvas. I've looked at CanvasLayout but I don't think that really helps me as the layout object is private to the Canvas. Any ideas are greatly appreciated.

[flexcoders] Custom Cursors causing slowdown
I'm experience an odd situation where when I have added a custom cursor the mouse movement is noticeably slower (although not massively obvious - although a colleague did point it out while testing the app). I've looked through my code and put traces everywhere and nothing is being called excessively that would cause the slowdown during this part of the app. Also if I remove just the custom cursor setting code then everything is fine and dandy. I'm running on the latest debug player on OS X, I can't say I noticed it when I was working on Windows - but then again I hadn't noticed it until my colleague pointed it out. I wondered if anyone else had experienced similar issues?

Subject: [flexcoders] View stack not changing in display even though

I have a view stack setup as a custom component, in it there is a
property call displaySection which is an int that corresponds to the
index to set the view stack. This is so that I can then use constants
for each of the sections external to the view and not worry about the
implementation within the view.
It is something like follows:
mx:Viewstack
...
selectedIndex={displaySection}
...
public static const SECTION_ONE:int = 0;
(etc.)
...
[Bindable]
public var displaySection:int = SECTION_ONE;
...
/mx:Viewstack
If I then change the displaySection externally and trace out the
selectedIndex and selectedChild of my component both are as expected,
however the very first time I do this without fail the display does
not change and the section displayed is always the default one.
However if I try and do it again then everything works fine.
I've tried swapping out the displaySection variable for a setter and
removed the binding and made the selectedIndex/selectedChild change
happen within commitProperties() and have traced out the initialized
property of my view and the length of the children and everything is
always as I expect it to be. However still no matter what I try
without fail on the first attempt to change the displaySection it
never works (always does thereafter --- but with nothing discernibly
different in the trace).
I've also tried changing the creationPolicy on the viewstack (and all
the viewstack children) to all, which didn't make any difference.
I've run through the debugger also and everything appears to be fine.
I'm really stuck and I'm ready to throw my computer out of the window.

Actually that didn't fix it either, I then had the strange situation
of two of the children showing at the same time in the viewstack.
The (hopefully final) fix I have now is to not have the Viewstack be
the root component in my custom component, now I have a Canvas as the
root in the custom component. Although this is a pointless container
in my case it does seem to fix the issue and even meant I could revert
to the binding I was first attempting to use. To me this looks like
there could be an issue with using a Viewstack as the root of a custom
component in some situations.

[flexcoders] Re: Global keyboard capture?
Thanks to this thread I've not bashed my computer to death today, I was getting close. I was having the same issue where after a given action the key up/down event handlers that I'd registered on the systemManager were no longer being triggered. What I was doing was this: Elsewhere within the app something else (who had a child which I'd explicitly given focus to via setFocus()) would get removed from the display (and left for G.C. to pick up) on a keyDown event. At this point the event handlers registered to the systemManager stopped picking anything up. It turns out that simply removing the item from the display doesn't release the focus, so I've manually given focus to the parentApplication when I remove it. This smells to me, am I doing anything wrong or is the behaviour you'd expect of focusing? Anyway I wouldn't have gotten to the bottom of the issue without this thread -- so many thanks.
[flexcoders] itemRollOver and itemDoubleClick not firing on datagrid
I can't figure out why this isn't working, I thought I was missing
something silly on Monday so didn't look at it all day yesterday in
the hope that a fresh view would show me the issue but I really can't
see what's going on.
Here's what I have:
mx:Script
![CDATA[
import mx.events.ListEvent;
private function doRollOver( event:ListEvent ):void
{
trace( 'ROLL' );
}
private function doClick( event:ListEvent ):void
{
trace( 'CLICK' );
}
private function doDoubleClick( event:ListEvent ):void
{
trace( 'DOUBLE CLICK' );
}

...
mx:DataGrid id=tasksGrid width=100% height=100%
dataProvider={tasksData} itemRollOver=doRollOver(event);
itemClick=doClick(event); itemDoubleClick=doDoubleClick(event);
...
/mx:DataGrid
I'm compiling with Flex 2.0.1 and the only think that I can get to
fire in the above example is the itemClick event.
I have tried adding the listeners via actionscript (within the
creation complete) but that makes no difference. I'm really not sure
why this isn't working.
Any suggestions are greatly appreciated.

The data grid is nested within an accordion which is inside a SuperTabNavigation but I'm not sure either of those are special cases.
[flexcoders] Re: Is setting custom headers on HTTPService for a GET possible?
Yeah this is the case with Flex, I think it has something to do with
the flash player (but don't quote me on that) -- I'm sure this
question will have been asked on here many times before so maybe you
can find a more detailed answer.
HTTPService definitely has some idiosyncrasies such as if you don't
include a request object then all requests are sent as GET, and
sometimes when you do set a request object requests are sent as either
GET or POST (based on the contentType set on the service). The fact
that all these idiosyncrasies aren't documented makes it very
frustrating to work with HTTPService sometimes -- and like I said it's
probably more down to the flash player than Flex's HTTPService.
I myself am trying to figure out how I can add to or override the
Accept header but haven't had much luck.

Using web browsers the custom headers are only included for POST when

Debugging a bit further shows that the same behavior happens when
using a URLLoader. Then the custom headers are not sent.
Under Air tho the custom headers are always sent, GET or POST.
These headers are all truly custom so they are not in the
URLRequestHeader blacklist.
Is there a way to set custom headers on a GET? Short of opening a

custom headers set on an HTTPService GET are not sent. Is this correct
or am I missing something?
var httpService: HTTPService = new HTTPService( );
httpService. method = 'GET';
httpService. headers = {customHeader: 'foobar'};
httpService. send({});

[flexcoders] Re: Is it possible to have a dynamic services/channel/endpoint URI?
I didn't know that you could use those placeholders in the URI, do you
know of any documentation on these - I can't seem to find any.
Although I've found a few examples which mention these 3 {server.name}
, {server.port}, {context.root} - is that all there are (not that I
need any more)?
Also I assume that is the preferred method of handling the URI (rather
than my rooting URI hack).

[flexcoders] Is it possible to have a dynamic services/channel/endpoint URI?
The backend portion of my app is setup the handle accounts automatically via an account key (which is currently set via the subdomain), e.g.: accountA.test.com will be restricted to accountA accountB.test.com will be restricted to accountB etc. I'm going to be putting a Flex frontend on all of this using AMF, but I can't figure out what to do with my service/channels as I don't really have a single endpoint URI - as it will be different for each account.

[flexcoders] Accordion, the FlexEvent.SHOW isn't fired the first time a panel is shown
I'm trying to add something into a panel in an accordion, I'm using the FlexEvent.SHOW to add the contents once the panel is displayed (this works pretty much everywhere else - e.g. a tab navigator). In my case trying to add the contents to a non visible element doesn't work (as I'm trying to get bitmap data), so I have to wait until they're visible before I can add my stuff. But in the Accordion it appears the FlexEvent.SHOW isn't fired the first time a panel is shown (the event listener added to the VBox that wraps panels content) -- it's fired the second time the panel is shown but never on the first time. I've tried listening for FlexEvent.INITIALIZE but that seems to be firing a little too early for what I'm doing. Basically all I need to know is as soon as a given panels content is displayed. I'd like a one solution fits all so for tab navigators etc. I only want to add my content when a non visible element becomes visible, but failing that I can add a specific workaround (if it's possible) to make it handle accordions different. Any ideas? Hope that makes sense. -D
[flexcoders] Re: Vertical scrolling without horizontal scrolling? How do I make 100% == 100%
Setting minHeight (everywhere I've already defined minWidth) doesn't resolve the issue either.
[flexcoders] Re: Vertical scrolling without horizontal scrolling? How do I make 100% == 100%
I too have been having problems with 100% widths and unwanted horizontal scrollbar. I've tried adding minWidth=0 to everything that has a width of 100% but that hasn't fixed the problem that I get an unwanted horizontal scrollbar. I've also tried using the reflex util (http://code.google.com/p/reflexutil/) to change these properties at run time to try and figure out what is causing the problem. What I (basically) have is the following: - (1) Tab navigator - 100% width -- (2) VBox (Tab contents) - 100% width --- (3a) Text --- (3b) HBox - 100% width --- (3c) Tab navigator - 100% width I get the vertical and horizontal scrollbars on the outer tab navigator (1) whenever the content gets taller than the app, in this case I obviously want vertical scrollbars and no horizontal scrollbars. With the reflex util I can change the width of the tab contents children (3a,3b,3c) and I still have horizontal scrollbar. However I cannot change the width of the VBox that wraps the tab contents (2) - it simply keeps resetting to the current value every time I try. I can see that it is the VBox (2) which is overlapping the vertical scrollbar (and thus causing the horizontal scrollbar) using reflex util. So I'm really stumped, I either need a solution to this, or a way to move the scrollbars from the tab navigator (1) to the VBox (2). Any advice would be greatly appreciated. -D
[flexcoders] Re: Adding custom events to the pre-loading sequence
rudmonster, an example would be good as I've not been able to announce
custom events from the app that the preloader seems to see, unless I
use the previous suggestion.
My solution to preload the stylesheets was to do it within the
preloader itself so have a 2 step preload, only once both steps were
completed did I announce the complete event.

(first time posting :)
All you need to do is extend mx.preloader.Download progressbar then
override the FlexEvent.INIT_COMPLETE you can then control when your
preloader will end ...see here (sorry ...I am paraphrasing my code dont
have it with me but you will get the idea)
public class Preloader extends DownloadProgressBar {
public var splash:SplashScreen;
public function CustomPreloader()
{
super();
splash = new splashScreen();
this.addChild(splash) ;
}
override public function set preloader( preloader:Sprite ):void
{
preloader.addEventListener( FlexEvent.INIT_COMPLETE ,
FlexInitComplete );
}
private function FlexInitComplete( event:Event ):void
{
splash.comp= true; // When this is true I know that the swf
has finished downloading
dispatchEvent( new Event( Event.COMPLETE ) );
}
}
so over riding and binding a var to true I can use another event (like a
database query result event to call another function inside of my splash
sprite .as file to remove itself like this:
public function startupComplete( event:ResultEvent):void
{
if( this.comp) closeSplash() ;
}
public function closeSplash( ):void
{
if( this.alpha 0){
this.alpha = this.alpha - fadeOutRate;
this.parent.removeChild(this);
}
}
if this sounds like what you want I can send you all my code to do this
.

[flexcoders] Modules + CSS issues, what are recommend practices
We have an application with each core section of the application being a module (as some users will get access to a restricted set of the app sections). We have all the CSS declared (via mx:Style source=... / tags) in the application MXML file. We then compile using a link report to optimize each of the modules for our application and everything seems to work fine. However now the application is nearly finished we just started to really skin the application (we started with the OSX stylesheet from scalenine and tweaked from there) everything looked ok until we noticed some oddities. The things we noticed were that you could click on a textarea within a module but you couldn't type into it and wherever date choosers are used we got the OSX style chrome on the date chooser but couldn't see nor choose any dates. Removing the OSX stylesheet fixed both of these problems. I tried tweaking the OSX stylesheet but that did not resolve the problem the only thing that I did which resolved all these strange issues was to include the OSX stylesheet within each of the modules themselves. I know I get a few warnings when compiling stating that certain CSS declarations aren't going to be evaluated, but the fact that the styles for things like the date chooser are in the app when the CSS is only in the main application is really confusing.

[flexcoders] Embedded asset management strategy
In my current project I'm going to be use a handful of icons in quite a few different classes. I was planning on embedding each of these into the application and was thinking that a single class with static properties would be the best way to go. For example if I had a IconAssetManager class which then handled the embedding of each of the icons and then everything that needs to use the icons can reference them from that single point. So I'm basically asking for a sanity check or any suggestions, has anyone else had experience of doing this? Also if I embed an image in more than one place (say as variables of each class that uses them) then I'm assuming that the image will be embedded multiple times into the .swf, is this assumption correct? Thanks in advance, -D

private function testShowEffect ():void
{
trace( 'testShowEffect ' );
Tweener.addTween( this, { y: this.height, time: 1 } );

But that method doesn't get called when I change the visible to true.

[flexcoders] List itemRenderer based on VBox error when verticalGap
I'm using the latest Flex 3 Beta SDK and I've just created an itemRenderer based on a VBox which I'm using in a List. Everything is fine until you scroll down and then back up to the top, if you do this the first item height will have shrunk and it will never resize. I tried overriding the measure() method but that didn't fix it, but I did notice that if I removed the verticalGap on the VBox that fixed the issue. I'm not sure if this is a known issue or not (haven't tried with Flex 2), but I could do with a workaround for when a verticalGap is applied (without adding extra containers) if anyone has any thoughts. -D
[flexcoders] Re: List itemRenderer based on VBox error when verticalGap
Actually now it seems the verticalGap isn't exactly the problem - I thought removing that fixed the issue but it hasn't, just made it appear 50% of the time when scrolling up and down to the top.
[flexcoders] Custom HTTP service causes Type Coercion failed error on dispatchEvent
I have a custom HTTP service, in this service I have done overridden

if( event.type == ResultEvent.RESULT ) {
theEvent = this.handleCakeResponse( event as ResultEvent );
}
return super.dispatchEvent( theEvent );
}

dispatched, I get the following error:

[flexcoders] Using getStyle() for styleName, how does it work with nesting?
I have a custom component, which gets a custom style name using
styleName={this.getStyle('myStyleName')}.
I'm using this component in a couple of places within a view and I
want it to be styled differently depending on where it is on the page,
for example:
HBox styleName=detailsWrap
Form
FormItem
MyComponent
HBox styleName=somethingElse
VBox
MyComponent
I assumed I could just set the following in the CSS:
.detailsWrap {
myStyleName: 'styleNameOne';
}
.somethingElse {
myStyleName: 'styleNameTwo';
}
But that doesn't appear to be working, if I inspect the components at
runtime then I see that the style name isn't been set. This appears to
be due to the nesting as if I do the following in the CSS:
MyComponent {
myStyleName: 'styleNameOne';
}
Then the style in styleNameOne does get applied.
I've also tried using child selectors, but I'm not sure if they're
really supported in Flex, e.g. I've done:
.detailsWrap * * MyComponent
But that doesn't work either.
Any ideas are greatly appreciated.

[flexcoders] Re: Flex is becoming unviable
It there was a way that I could load the modules in the background while the user is doing other things would be great, then it would be there right when I need it. A quick Google search would have shown you that this is possible with modules, by doing ModuleManager.getModule(MyModule.swf).load();, this will load the module but not display it, so when it's time for you to display it it's already been loaded. However the only time you should really do that is if you're sure the user is going to use that module while using your app. One of the most common cases for using modules seems to be when you have sections of your app (e.g. a preferences section) which the user isn't always going to require - so you only load that when they want it. -D
[flexcoders] Re: Mock objects in AS3
Bjorn,
I have been looking at this (as I would like a mocking framework for
Flex too) this evening and I've had no luck either.
The the registerClassAlias() does add the alias to a given class I
can't then get anything to accept it as being of that type
- I'm not sure what the alias is, but dumping the describeType()
results shows it as an alias property on the type and not as an
implementsInterface node, which is what we need.
I may not have been fully understood what registerClassAlias though.
But it looks (ok, it's late and I'm tired so it may just be that which
is causing my negativity) as if trying to get a class to implement an
interface (or at least appear to implement an interface) dynamically
at run time is a futile effort.
Any thoughts?

Here is what I did during my 20 minutes of playing:

var desc : XML = flash.utils.describeType(c);
var str : String = desc.toString();

a[setSomething] = function(something : String) : void {
trace(something); };
// will fail on the following line, since a does not implement
TestInterface.
i = TestInterface(a);
i.setSomething(blah);
}
AS3 doesn't support duck typing like Ruby, and I believe there is no
way to get an object in memory that implements the TestInterface
interface that my other objects can use as a mock.
Any thoughts about this? Am I doomed to use elbow grease or code
generation to create these things?

[flexcoders] New ComboBox component
Just a quick note to let you know that I've released a new ComboBox component that implements option selection as you type, unlike the default ComboBox it does it on part words or full words. This is handy for quickly jumping to a known option in a large list of options within the ComboBox. I just created it as I had gotten so used to that kind of functionality within drop down boxes (in Firefox especially) that I really missed it within Flex. If you're interested an example, description and the download can be found here: http://www.defusion.org.uk/code/foxycombobox-for-flex/
