You can always create a typed ActionScript VO. Since you'll have to go from
ResultSet to typed object on the Java side before you can use the built-in
marshaller, you may as well just marshal straight from your resultSet to
AMF.

 You could put them in a list of HashMaps, which should get serialised into
 an Array of simple name-value objects on the way to the Flex client?

 2009/4/14 Daniel Freiman freima...@gmail.com



 Yeah, something more raw.  If the ResultSet was natively serializable (w/
 multiple rows of data), I'd be happy.  I've found from previous iterations
 of this project, that raw-ish data was the way to go here, and previous
 languages I used easily allowed for that.

Re: [flexcoders] Extending Flex Webservice class

There's currently compile-time voodoo that exists to support the MXML

though, what exactly are you trying to do?

Re: [flexcoders] Pros and Cons of Writing Air UI's in Pure Flash

2009-04-06 Thread Josh McDonald

Personally, I'd think long and hard before doing something like this. It
really depends on how much of the actual work is in the very top layer of
frosting, how much work is done in the meat of the AIR app, and what kind
of feedback you need to have going between these layers.

Perhaps you can get the designers to build simpler components (buttons,
window decorations, etc) in Flash using the FCK, and lay them out with MXML
and Builder. If they're building SWCs with the FCK at least they can expose
[Event] metadata and such, which will make life easier for whoever needs to
tie things together in Builder for the AIR side of things. I'd be very loath
to make SWFs part of my app for anything more complex than image resources.
If it generates Events and exposes an API, I need to interact with it
without regard for its internal timeline, the possibility of memory leaks
caused by loading SWFs (mainly in Player 9), etc.

I agree with them 100% that compile-time is horrible for Builder. Adobe
knows this, and they're working on it. Building from Ant using MXMLC rather
than Builder is apparently faster as-is, and I believe you can get a
signifigant speedup using the compiler from Flex 4 but building against Flex
3 libraries. This opens you up to issues as Fx4 is still in early
development, but most of the changes these days appear to be happening in
Spark and the new MXML stuff, so building against the old namespace using
the Halo components could be a helper. Also, recently on the FlexShow
podcast they interviewed a guy (sorry, name escapes me) who's been
backporting some of the speedups from Fx4 into Flex 3. They're not part of
the official download, but I believe you can patch the compiler source,
recompile with Java, and reap the benefits of his hard work without the
technical risk inherent in building using the WIP Gumbo toolchain.

Enough ranting and suggestions from me, I think - time to yield the floor!
:)

-Josh

2009/4/7 Scott Delap scott-li...@richclientsolutions.com

   I have a question for the list. We are currently doing rapid UI
 changes to our Air application. Our UI designers that have experience
 with Flash have not been happy with the iteration turn around time of
 skinning our UI's. Complains range from issues with compilation
 time to being able to easily preview changes. They have proposed that
 we develop our UI's in pure Flash with only Flash level UI controls.
 We'd then embed these UI's as swfs in our Flex/Actionscript code. I
 can see doing this for some UI components. However, I must admit I'm
 very hesitant to implement the entire UI this way since it becomes one
 big passive view black box. Would anyone else have pro's or con's to
 such an approach?

   Hi,

 I'm using DragManager to drag some objects on the interface. And I'd like
 the dragging to be cancelled when the ESCAPE key is pressed. But I can't
 find a way to do it since DragManager doesn't seem to have a method for
 that.

 Here's what my code looks like:

 private function keyHandler(event:KeyboardEvent):void {
 if (DragManager.isDragging  event.keyCode == Keyboard.ESCAPE){
 // TODO: Cancel drag here...
 stage.removeEventListener(KeyboardEvent.KEY_DOWN, keyHandler);
 }
 }

 public function startDrag(event:MouseEvent):void {
 ...
 DragManager.doDrag(dragInitiator, dragSource, event, image);
 stage.addEventListener(KeyboardEvent.KEY_DOWN, keyHandler);
 }

 Do you know how I could achieve this?

 Thanks a lot,

 Julien

Re: [flexcoders] Re: Question about binding and circular reference

2009-03-18 Thread Josh McDonald

Also, try using commiting event only bindings for the trip back to the
model. I don't use it so I'm not sure, but it might be exactly what you're
looking for.

My View Model system doesn't have these problems (and keeps track of dirty
fields, etc), but it's wordy. I do some code-generation with a combination
of BeanScript voodoo in JEdit and a custom Flex app, which cuts down on the
work. I'm not 100% happy with my pattern yet, and need to write a helper
util to better manage binding events, but it's getting close to good enough
to release to the public :)

2009/3/18 enriirne enrii...@yahoo.it

   Is there anything more sweet than write a long post and see it vanish in
 the air?
 Perhaps Chrome plus Flexcoders' Rich-Text Editor (Beta) is asking too
 much :)

 I'll try again, shorter version.


  Another approach, if you're set on binding: Rather than the outer
  component waiting for creationComplete on the inner component to set the
  model value, simply put code in the inner component that waits for
  creationcomplete and creates the component-model return bindings
  programmatically via BindingUtils.

 Hi Josh.
 I didn't give up on bidirectional binding, but I admit to be close to the
 metal :)
 The strategy that seems to work is this:
 - a value object with two methods: saveOriginal and restoreOriginal, also
 useful to manage the form's cancel button
 - binding through BindingUtils into createComplete
 - a mono-binding for date fields, because of a bug in DateField.as

 Here is some code. In case of interest, I'll post the implementation.
 bindForCreate does a single bind, while bindForUpdate does two.

 Enri

 // a form
 [Bindable]
 public var vo:SomeVO;

 [Bindable]
 private var voOut:SomeVO;

 private var cws:Array = []; // used later to unbind

 private function creationComplete():void {
 if (vo.isNew) {
 extend(cws, bindForCreate(vo, 'date', datefield, 'selectedDate'));
 extend(cws, bindForCreate(vo, 'name', nameField, 'text'));
 } else {
 voOut = new SomeVO();
 vo.saveOriginal();
 extend(cws, bindForUpdateException(vo, voOut, 'date', datefield,
 'selectedDate'));
 extend(cws, bindForUpdate(vo, 'name', nameField, 'text'));
 vo.restoreOriginal();
 }
 }

Re: [flexcoders] Question about binding and circular reference

2009-03-17 Thread Josh McDonald

I re-read the original post, and it makes sense. I always use change events
rather than bindings on the way back from components, which is what I'd
recommend rather than two-way bindings. I'm interested to see how the SDK
team handles this with the bidirectional binding feature in 4.

Another approach, if you're set on binding: Rather than the outer
component waiting for creationComplete on the inner component to set the
model value, simply put code in the inner component that waits for
creationcomplete and creates the component-model return bindings
programmatically via BindingUtils.

Not sure I've explained that clearly tho, let me know if it's gibberish :)

-Josh

2009/3/17 Wesley Acheson wesley.ache...@gmail.com

   My problem and I believe enrinne's problem is that when you have two way
 bindings on a ui control. The initial value of the control is set back in
 the model. I've seen this on textInput and comboBox.

 I can create a sample application but I think it would be very similar to
 the first post in the thread.

 I'd like to prevent the reverse binding occuring until the control is fully
 initialisaed.

Sorry for resurecting an old thread. I've reciently given up on this.
 I've gone back to using event listeners.  It seems more reliable.  The
 problem as I see it is that the binding events happen for any old reason.
 The change events only seem to be triggered on user interaction which is
 much better IMHO.

  The problem you are experiencing is caused by the fact that when the

 thus
 overwrite what was in foo.

 If you want to avoid this, you need to do:

 protected var mf:MyForm = new MyForm();
 mf.addEventListener(FlexEvent.CREATION_COMPLETE, formCreatedHandler);
 addChild(mf);

   In the flex documentation, it shows how to easily create a chart with
   mxml and a static Array:
  
   private var expenses:Array = [
   {Month:January,Profit:2000,Expenses:1500,Amount:450},
   {Month:February,Profit:1000,Expenses:200,Amount:600},
   {Month:March,Profit:1500,Expenses:500,Amount:300},
   ];
   mx:ColumnSeries
   xField=Month
   yField=Profit
   displayName=Profit
   /
   mx:ColumnSeries
   xField=Month
   yField=Expenses
   displayName=Expenses
   /
  
   But I am reading my data from the database and want to pass the data
 via a
   java object. But I don't know the number of fields at runtime. So how
 do I
   assign the xFields and yFields since I won't be able to create a
 variable
   named Month or Profit? I'll just have an array of floats or dates
 or
   whatever. Here's a start put I have no idea how to plug in the missing
   pieces or if another route would be preferable.
  
   var lineSeries:LineSeries = new LineSeries();
   BindingUtils.bindProperty(lineSeries, dataProvider, ser,
 javaArray);
   // lineSeries.xField= ???
   // lineSeries.yField= ???
  
   The data set is often quite large by the way.

Re: [flexcoders] XML Entity won't parse inside MXML

The (xml source code) - XML|XMLList stage in MXMLC isn't so good. Often I
need to embed XML as Binary objects, and go via String to parse it.

That's not much useful information though, so the answer to your problem is:

mx:XMLList id=testXml
sample badattribute={ABC}

test name=1/
test name=2/
/sample
mx:XMLList
Note that despite the similar syntax I don't think these expressions are
updated when input changes the same way bindings are. They *might* be when
you're using .MXML, but the same syntax can be used to mix XML literals and
ActionScript expressions in .as files.

   I have some embbeded XML inside an MXML file that I'm feeding to an
 outline. Some of my attributes need to have a quote character. It looks
 something like this

 mx:XMLList id=testXml
 sample badattribute=quot;ABCquot;
 test name=1/
 test name=2/
 /sample
 mx:XMLList

 This refuses to compile.

 I even ran a test where I omitted, the badattribute from the xml and then
 in the code I did something like this,

 testx...@test = 'ABC';
 trace(textXml.toXMLString())

 and it printed it out correctly using quot; as the quote character.

 Does anyone have a clue as to what's going on?

 Thanks,
 Mark

Re: [flexcoders] XML Entity won't parse inside MXML

Also note that the curly braces go *outside* the quotes - if you were
putting the number 7 in your attribute, it would be

element attr={7}/

If you do this:

element attr={7}/

Then your attribute will have the value of {7} instead of 7.

any posts from you in this thread.

2009/3/17 Wesley Acheson wesley.ache...@gmail.com

   Sorry for resurecting an old thread. I've reciently given up on this.
 I've gone back to using event listeners.  It seems more reliable.  The
 problem as I see it is that the binding events happen for any old reason.
 The change events only seem to be triggered on user interaction which is
 much better IMHO.

  The problem you are experiencing is caused by the fact that when the

 created in your form yet. So, the foo-myText binding does nothing and when
 the text input is finally created, the myText-foo binding executes and thus
 overwrite what was in foo.

 If you want to avoid this, you need to do:

 protected var mf:MyForm = new MyForm();
 mf.addEventListener(FlexEvent.CREATION_COMPLETE, formCreatedHandler);
 addChild(mf);

 protected function formCreatedHandler(event:FlexEvent):void {

 Indeed, if I do this in the main app:

 then myText is empty, probably because it's empty content is first
 assigned to foo due to the second binding.
 The real problem I'm trying to solve is to use the same value object to
 show data to the user and to receive his/her changes.

 Of course it works if I use two vos: say voIn and voOut, binding them
 accordingly.

 Any ideas?

Re: [flexcoders] To Adobe Folks - General Question About Using Deprecated Tags

I can't speak for Adobe, but as a *general* rule (ignoring the JDK),
deprecated means it's not going away in a point-release, but it's going
away So you souldn't count on it in 4, but you're probably fine for updates
of 3. But either way, there's nothing forcing you to upgrade your app to a
new SDK version anyway.

Again, I don't speak for Adobe :)

Also, if you need the deprecated API to get around a valid bug in the SDK,
make sure to make a note of it in Jira so the Adobe guys can keep it in
mind.

2009/3/17 EddieBerman eddieberman2...@hotmail.com

   I posted a related question here a few days back (ColumnCharts -
 problem adding a LineSeries to ColumnChart w/o SecondSeries), but this
 question is a bit more general.

 In order get past this bug -
 https://bugs.adobe.com/jira/browse/FLEXDMV-1957, I'm likely going to need
 to use the deprecated SecondSeries tag. My question is how safe is using
 this, or any of the other deprecated tags, methods, etc. I read what I could
 find in the docs, but what I saw seemed more focused on layout style
 differences.

 Is there an expectation that support could be dropped in future versions,
 or are these warnings simply there to point us to the newer, improved-upon
 replacements.

 Thanks,

Re: [flexcoders] Re: FocusManager fun... Tab Loops redux

Sounds like a good time to break out your SDK sandbox :)

2009/3/16 Rick Winscot rick.wins...@zyche.com

Even the PopUpManager suffers to a degree. As modules are loaded there
 seems to be some confusion as to which FocusManager they belong...  as you
 press TAB focus will jump from one module to another as if they were
 connected. You can get around this by forcibly triggering
 activate/deactivate operations on the modules FocusManager --- as stated in
 the comments in FocusManager.as:

 “The SystemManager activates and deactivates a FocusManager if more than
 one IFocusManagerContainer is visible at the same time. If the mouse is
 clicked in an IFocusManagerContainer with a deactivated FocusManager, the
 SystemManager will call the activate() method on that FocusManager. The
 FocusManager that was activated will have its deactivate() method called
 prior to the activation of another FocusManager.”

 I’ll attach a sample project to the issue for clarity.

Since the documentation seems to indicate that FocusManager will

My primary goal, irrespective of how I do it is to create what I call

   Hi All,
My flex2  *DataGrid*  has got at least *50 columns* of type Date.I
 also have list which opens when use select  a context menu item ,in this
 list user can select  any no of columns on which he wants  multiple sorting
 to be happen.

 Lets say user has selected 5 Columns for multi sorting,I create 5 sortField
 with compareFunction in loop as follows

   var sortFieldArray:Array = new Array();
   for(var *dataField *in *selectedColumnArray*){
 var field:SortField = new SortField(dataField );

  field.compareFunction = function(itemA:Object,itemB:Object):int{
 var dateA:Date =itemA[*dataField *] ;
 var dateB:Date =itemB[*dataField *] ;

  .
  }
 sortFieldArray.push(field);
   }
 Problem which I have been facing is ,local var dataField is always
 referring to the last value of *selectedColumnArray *hence sorting is
 happening based on last column only.

 I dont want to create separate compareFunction for each column , simply
 because at compilation time I dont know about the no of column which user
 can choose to participate in multipleSorting.And I dont want to create 50
 compareFunction with *hardcoded dataField* name


 Is it possible to create *GENERIC compareFucntion *which can take
 dataField without hard coding ?

 Please throw some light on this it?

 Kind of like the toolbar for picking controls in Adobe Dreamweaver

 (unless they've changed it in recent versions).



 Unfortunately I haven't heard of any Flash implementations, only

 Silverlight implementations. You could implement it yourself using a

 TabNavigator and Panel controls inside each tab for groups, and

 buttons inside them. It's the styling that will be a pain - the

 official specs are available from Microsoft for free though, with some

 conditions attached

 (http://msdn.microsoft.com/en-au/office/aa973809.aspx). You could also

 use the images and even code if you know XAML from the Silverlight

 version - http://silverlightribbon.codeplex.com/



 Personally I'd be making my own interpretation of the ribbon control

 instead of following the Microsoft version to the dot, especially

 seeing as they have changed a few bits in Windows 7 which will

 probably filter down to Office in Office 2010 (e.g. the confusion with

 the File menu - the Orb in the top corner is now gone).

Re: [flexcoders] Re: binding not updating for ArrayCollection when item changes?

In your custom control, change this:


public function set dataProvider(dp:ArrayCollection):void {
_dp = dp;
trace(this fires when the AC is created, but not when it's contents
change);
}

to something like this:


public function set dataProvider(value : ArrayCollection) : void
{
if (_dp == value)
return;

if (dataProvider)
dataProvider.removeEventListener(CollectionEvent.COLLECTION_CHANGE,
handleUpdatedProvider);

_dp = value;

if (dataProvider)
dataProvider.addEventListener(CollectionEvent.COLLECTION_CHANGE,
handleUpdatedProvider, ???, ???, true); // Weak listener!

handleUpdatedProvider(null);
}

private function handleUpdatedProvider(event : CollectionEvent) : void
{
//... do stuff
}


Note that this is just typed out of the top of my head, probably full of
typos, and you need to put the default options in place of ??? when
attaching the listener :)

2009/3/13 John Robinson jrobi...@nycap.rr.com

   Yeah, I've been directly updating the properties. Here's the weird
 part... if I use the ArrayCollection as a dataProvider for a List control,
 it updates. If I use it for a custom control that I've created, it does
 not.

 Example:
 This works as expected:
 mx:List dataProvider={model.users}/

 This does not:
 jr:customComponent dataProvider={model.users}/

 //pseudo component source
 customComponent
 mx:Script
 private var _dp:ArrayCollection;

 public function set dataProvider(dp:ArrayCollection):void {
 _dp = dp;
 trace(this fires when the AC is created, but not when it's contents
 change);
 }

 /mx:Script
 /customComponent

Re: [flexcoders] Building Custom ActionScript Components with Skins

2009-03-11 Thread Josh McDonald

Is the size of the component a big question? If not, I'd go with Flex
because then you can use Degrafa. The team is working on removing
inter-dependencies and also removing the dependency upon Flex (via
UIComponent), but that's not ready yet, so it does add some weight to your
.swf files.

-Josh

2009/3/11 adamduro a...@duromedia.com

   So I am trying to build out a custom SimpleMp3player component. Here is
 a screen shot of what the current design for this looks like:

 http://storage.duromedia.com/mp3_player_ui.jpg

 I want to create a custom component that will contain all the functionality
 that the above UI illustrates, but I want to make the component as easily
 skinable for the future as possible. Preferably skinable by a designer, and
 not a developer.

 I have considered a few routes.

 1) The one I am most comfortable with is building a custom component with
 the Flash IDE, and custom AS3 classes, then export out using the Flex
 Component Kit. As far as I can see, the draw back to that is the skin has to
 be customized using the Flash IDE from then on out.

 2) The other route I considered was building the whole thing in Flex, and
 using a style attribute to feed in a SWF based skin file. This is something
 I'm starting to get more familiar with, but I'm still a long ways off from
 mastering the art of pure Flex custom components.

 First off, if anyone has any opinions on which of the above two routes
 would be best, please speak up. If there are other routes to take, do tell.

 Second, If anyone has any good resources (besides the Flex 3 LiveDocs) on
 building out custom components that utilize Skins as outlined in option 2,
 please pass those along.

 Third, if anyone feels like tackling any of these specific questions, I
 would love some help:

 - When creating a skinnable ActionScript component, do I have to create a
 style property for each UI element? (ie. playButtonUp, playButtonDown,
 seekBarTrack, seekBar, etc.)

 - Can I use the skin file to put together the layout of the component, or
 do I have to do that programatically with ActionScript? I would love if I
 could do a layout in Illustrator that had all the elements of the
 MusicPlayer component positioned where I want them, and then feed in a
 single Symbol (containing the other symbols) so that the UI component
 maintained the layout as it was set in Illustrator.

 Any help with any of the above would be met with great appreciation.

 Best,

 Adam Duro

Re: [flexcoders] Tables in Rich Text Editor

2009-02-06 Thread Josh McDonald

I'd definitely be interested in extending TLF when it's released. Is it
going to live in Player, or in the Flex framework? If the latter, why would
it not be open sourced? Is it going to be part of Builder pro? Am I dreaming
hoping for answers to those questions? ;-)

-Josh

On Fri, Feb 6, 2009 at 3:48 PM, Gordon Smith gosm...@adobe.com wrote:

The Halo RichTextEditor component will never support tables; it is
 based on the Player's TextField, and the Player team has no plans to improve
 TextField. Instead, the Player team has provided, in Flash Player 10, an
 entirely new text engine known as FTE (Flash Text Engine) on top of which a
 Text Layout Framework (TLF) library is being developed. Gumbo components --
 including the new FxTextArea -- use TLF to do their text rendering. And
 we're working on making it possible for Halo components to also get some TLF
 capabilities.



 The first version of TLF, which will ship with Gumbo, will support cool
 stuff like bidirectional text (for right-to-left languages like Arabic and
 Hebrew mixed together with left-to-right languages), virtualized scrolling
 (so that you can scroll through large amounts of text without requiring too
 much memory), multiple columns, vertical Asian text, embedded graphics,
 superscripts/subscripts, ligatures, a better markup language, and a text
 object model, but… it will unfortunately not support lists or tables. : (



 Lists and tables are scheduled for a future release of TLF, after Flex 4.
 The good news is that new versions of the TLF library will be able to be
 released more quickly and easily than new versions of the Player, so you
 shouldn't have to wait too long for improvements.



 Discussions are also underway about open-sourcing TLF, or at least making
 its source available, in which case you could try implementing tables
 yourself if you are very ambitious.

Re: [flexcoders] Re: Getting at variables inside a function that accepts a function

2009-02-06 Thread Josh McDonald

It's not possible, any closure only has access to the variables in scope
when it is defined.

function foo(a,b,c,f)
{
  var bar = function() {//has access to everything in foo}
  function baz() {//Same as above}
}

var bash = function() { //Does not have access to what's in foo() at any
time}

foo(1,2,3,bash) //Doesn't suddenly give access to foo's locals.


Think of it this way - if what you wanted were possible, then what would
happen if I just invoked bash() instead of passing it to foo()?

There are tricks to achieve something similar to what you want, but they
require changing foo(), in which case you only need to pass arguments to the
f() function.

 No as the functions are in separate classes and the var a, b, c, d are
 private so in my class that calls the remote function I get Undefined
 property a.

 What about putting the vars in as params? Then I think there is a way
 to access the params by order, correct?

 So something like this to get at a in this example

 public function acceptingFunction (func1:Function=null,
 func2:Function=null):void{
 var a:Number;
 var b:String;

 if(func1  func2){
 if(func1(a=43))return true; --- inserting local param
 anotherAcceptFunction(func2);
 }
 }

 Then do this...

 acceptFunction(function():void{ whatever code is to get at params by
 order params[0]?});

UIComponent doesn't have any code for drawing background images. If you want
a background image without the overhead of using a Container such as Box,
you'll have to build a subclass of UIComponent that does. Or simply add an
Image as the first child of your UIComponent. Are you extending UIComponent,
or just instantiating them because you want someplace to put an image?

 Nice link :) I tried to implement code as per the examples in the link
 page, but the problem is I can never get an image to show as the
 background of a UIComponent! This would let me alter the image based
 on different stylesheets which are loaded at runtime.

 The way I do it now, I add an HBox to a UIComponent and set that as
 the bkg and add the styleName to that. I must be missing something
 somewhere to enable a background image on a UIComponent. Again the
 reason for using a UIComponent is that it's lighter.

 sorry for the rant :(

Re: [flexcoders] Re: FadeIn Effect not working with custom item renderers in List

2009-01-21 Thread Josh McDonald

It may be caused by Container not implementing IDropInListItemRenderer or
IListItemRenderer. You really don't want to be extending Container for item
renderers if you can avoid it, I believe it's a big performance penalty.

 Perhaps I should have been clearer in my original description. The
 issue seems to be related to the use of containers as custom
 renderers. While I admit that in this case, removal of the container
 solves the issue, this is just a simple case to demonstrate the issue.
 In my real life case, my item renderers are much more complicated,
 containing many sub-components, hence the use of containers.

Re: [flexcoders] FB debug constantly logs to console

2009-01-20 Thread Josh McDonald

You're probably loading images or something along those lines using a
SWFLoader or one of its subclasses such as Image. This is simply Player
telling you about it decoding the results and adding them to the VM.

-Josh

2009/1/21 John Van Horn jmvanh...@gmail.com

  All of a sudden a few days ago, launching a debug session in FB3, results
 in FB (or maybe debug player) logging constantly to the console. I get about
 2 of these messages a second, and it doesnt stop till I terminate the debug
 session. This does not output to flashlog.txt. It makes reading traces in FB
 console very difficult.

 Anybody experienced this or know a solution?

Re: [flexcoders] Re: Add effect dynamically

2009-01-20 Thread Josh McDonald

You can use Strings, but they might need to be fully qualified when doing it
from ActionScript instead of CSS. You can also use

obj.setStyle(moveEffect, Move);

and

obj.setStyle(moveEffect, myMoveInstance);

Note that myMoveInstance would be an instance of mx.effects.Move, *not* an
instance of mx.effects.effectClasses.MoveInstance

 Haven't tested this, but this might be a way to accomplish it:

 var btn:Button = new Button();
 btn.setStyle(mouseDownEffect, glowImage);
 btn.setStyle(mouseUpEffect, unglowEffect);

 Will try it in the morning. Didn't realize effects were set using styles.

This method is 10x faster, and more accurate (although the word is
meaningless at such scale due to the nature of IEEE floats):

private function safeBitCheck2(l : Number, r : Number) : Boolean
{
if (r  l)
return false;
if (r == l)
return true;
if ((l = uint.MAX_VALUE)  (r = uint.MAX_VALUE))
return (l  r) == r;

var rs : String = r.toString(32);
var ls : String = l.toString(32).substring(-rs.length);
var split : uint = uint(rs.length)  1;

if (safeBitCheck2(parseInt(ls.substr(0, split), 32),
parseInt(rs.substr(0, split), 32)))
return safeBitCheck2(parseInt(ls.substr(split), 32),
parseInt(rs.substr(split), 32));

return false;
}

What on earth do you actually need this function for?

Re: [flexcoders] flex not seeing method - update

2009-01-18 Thread Josh McDonald

The mx:Component tag is, let's call it... Voodoo :)

What it's actually doing is defining a new custom component class, whereas
every other MXML tag you use will define elements of the class defined in
the root element of your MXML document. You can tell MXMLC what name you'd
like the class to have in order to reuse it later, but otherwise it just
picks an unused ugly name for you. So you need to think of everything inside
your mx:Component tag as if it were in a completely separate MXML file.
And becuase we don't have inner classes in ActionScript, you don't have
access to members of the parent class the way you normally would expect
to.

If your handler is on Application (and public) you can get to it from a
renderer using Application.application.handler_resize(event). But I prefer
to dispatch bubbling events from within the custom component, and then put
listener code in the containing object.

 Subject: [flexcoders] flex not seeing method - update


 
  Ok, I found one additional piece of info that when I sent this I
  thought was not relevant. In my main.mxml, my component.mxml is
  actually an itemrenderer. So the code for it would be:
 
 
  mx:itemRenderer
  mx:Component
  view:fileActions DownloadResizeEvent=handler_resize(event)/
  /mx:Component
  /mx:itemRenderer
 
  Instead of :
  view:fileActions DownloadResizeEvent=handler_resize(event)/
 
  Now the reason this seems relevant is because if I comment out the
  item renderer code, and place just a single instance of my
  component.mxml in my main.mxml - it works fine. No more errors.
 
  So to sum up when a custom component that dispatches a custom
  event is placed within the above mxml code - it will not see the
  defined event handler.
 
  ideas?

 Try making the handler public..

  Hi there, I have an mxml component that dispatches an event. Now
  when i use the component, the meta data is showing up fine. But when
  i assign a handler, flex says that it is a call to a possibly
  undefined method. But it is there plain as day. IDeas???
 
  Code snippets below.
 
  DownloadResizeEvent.as - pretty stock custom event:
 
  package elib.event

  {
 
  public static const DOWNLOADRESIZE_EVENT:String =
  downloadresizeevent;
 
  public function DownloadResizeEvent(type:String):void
  {
  super(type);
  }
 
  // Override the inherited clone() method.
 override public function clone():Event {
 return new DownloadResizeEvent(type);
 }
 
  }
  }
 
  now in my component.mxml:
 
  (in a script block)
 
  snip
  import elib.event.*;
  //snip
 
  (in same script block)
 
  snip
  //located in a method
  dispatchEvent( new Event(DownloadResizeEvent.DOWNLOADRESIZE_EVENT) );
 
  //snip
 
  Then later in my mxml
 
  snip
  mx:Metadata
  [Event(name=DownloadResizeEvent,
  type=elib.event.DownloadResizeEvent)]
  /mx:Metadata
  //snip

  main.mxml
 
 
  (in my root tag)
 
  snip
  xmlns:view=elib.view.components.*
  //snip

  Josh is probably on the ball. Also check out outerDocument:

 The mx:Component tag defines a new scope within an MXML file, where the
 local scope of the item renderer or item editor is defined by the MXML code

 block delimited by the mx:Component and /mx:Component tags. To access
 elements outside of the local scope of the item renderer or item editor,
 you
 prefix the element name with the outerDocument keyword.

2009-01-17 Thread Josh McDonald

Well if you're working against MXML and don't also have a compiled .SWF for
that application, you're just going to have to hard-reference everything you
might need, or load it from the Flex library SWC (a SWC is just a .SWF and
an XML file in a zip)

Failing that, since it sounds like you're doing analysis, just run your code
against all the UIComponents in the framework, and just keep the data :)

 an object, and I haven't found a way to get an instance of a non

 This must be a problem regarding the compiler domain. I don't know if

Re: [flexcoders] Why this error with getDefinitionByName?

2009-01-15 Thread Josh McDonald

Also, if you do that in a SWF that doesn't actually *use* the TextInput
symbol, the class won't be compiled in. Try adding a reference to TextInput
- not just an import, you actually have to have a reference. import
mx.controls.TextInput; TextInput; should do it.

Re: [flexcoders] Custom mouse cursors including the system cursor?

2009-01-14 Thread Josh McDonald

I tried to just follow up with a Mouse.show on next frame, but CursorManager
calls Mouse.hide on every frame. For now I'm simply working around the
problem by switching all my drag cursors to a little grabbing hand :)

I sure do miss mc.startDrag() from Flash MX sometimes...

 Why not just draw the custom cursor next to the system cursor?
 CursorManager does Mouse.hide. If you skipped that, you would end up
 with a composite cursor.

 Maybe CursorManager should have an option for this.

Re: [flexcoders] Custom mouse cursors including the system cursor?

2009-01-13 Thread Josh McDonald

I was poking around in the .fla file, I thought there was some process by
which the cursor symbol is replaced with the system cursor... If not, does
that not mean then that under windows, when you drag over something you
can't drop on, and it switches to mx.skins.cursor.DragReject the pointer
also changes to look like the black OS X pointer?

That's an awful sentance, let me know if I need to try and explain it again

Re: [flexcoders] Using dispatchEvent ?

2009-01-11 Thread Josh McDonald

Event bubbling only occurs within the display list. So your dispatching
object must also be a child UIComponent if you want to catch bubbled events.

-Josh

On Mon, Jan 12, 2009 at 4:12 PM, biosmonkey biosmon...@yahoo.com wrote:

 I thought I had understood the event model, but apparently not.

 I have a custom class that extends EventDispatcher, let's call it
 MyClass.  This class will periodically dispatch a custom event based
 on a timer and some condition.

 In my main app, I instantiate an instance of this class.  I also
 create an event listener at the application level.

 Here's the problem:

 * If I use dispatchEvent(...) inside MyClass, the event listener in
 the main app never fires (the custom event *is* set to bubble)

 * The only way it will work is if I use the application object, ie
 mx.core.Application.application.dispatchEvent(...)

 But I don't understand why I have to do this? I have used a similar
 model just fine when dispatching events from inside components (ie I
 use dispatchEvent and my custom event is heard at the app level via
 bubbling).

 Can someone help me understand this?

 When you listen for an event on one of your ancestors, you usually
 want to use a weak reference (the last parameter to addEventListener).
 That's because your parent doesn't know you're listening on it, so
 when you've been removed and discarded, you'll still be around
 because of the event listener.

Re: [flexcoders] Re: Newbie question: Completion Events or proxy binding for RemoteObject calls

The BindUtils doesn't work quite like that. Let's take this MXML snippet:

Re: [flexcoders] Re: Properly remove children

That is however a corner case, and although I've deleted my experiment, it's
pretty easy to show that weak event listeners do get collected most of the
time.

 Hi,

 Just wanted to mention something I (in the comments) of one of Ted
 Patrick's blog posts.

 He says that there's a known bug in Flash Player 9 where weak references
 were preventing
 objects from being garbage collected:

 http://www.onflex.org/ted/2008/09/useweakreferencesboolean-false.php

 From earlier reading, I started to use weak references for when ever
 possible, and thought
 I didn't have to worry about removing the event listeners. I upgraded to
 Flash Player 10,
 however, it still seemed like the weak refs were preventing GC (admittedly
 a newbie
 w/using the Flex Profiler).

 This very last comment on this JIRA bug seems to have reached the same
 conclusion as I
 have, that the issue may not be 100% fixed in Flash Player 10:

 http://bugs.adobe.com/jira/browse/FP-291

 Suffice it to say, I have adopted the sage advice of others on this list
 and now always
 remove any listeners that I add (weak ref or not).

 HTH,
 Sunil

  buttons to trigger properly.  However, I've lost the button skinning
  for mouse Over, down, disabled, click, etc...  The skin is a
  programatic skin that has implementations for downSkin,
  selectedOverSkin, overSkin, selectedUpSkin, etc...
 
What would be the preferred way to get the HBox (or any container)
  to act like a button with custom button skinning, and at the same time
  be able to have nested buttons that would take priority when the mouse
  hovers over them?  I'd like to think I'm missing something trivial in
  getting this to work because it seems like a pretty common use case.
 
  Thanks for any suggestions.

Re: [flexcoders] Animated border around thumbnails - similar to MTV header

I'd make the border a Degrafa surface (or just a mx:Box with a border).
Add a moveEffect and a resizeEffect, put it in the same container as the
thumbnails, but last in the list so it'll be on top. If they're in a hbox or
something like that and you don't want to mess up the layout of the
container, set

myBorderComponent.includeInLayout = false;

And it will be in the same container but won't affect the layout. Then,
every time you want to hilight another thumbnail, simply call:

myBorderComponent.move(nextThumbnail.x, nextThumbnail.y);
myBorderComponent.width = nextThumbnail.width;
myBorderComponent.height = nextThumbnail.height;

And the moveEffect and resizeEffect should do the rest.

 Hi everyone,
 I'm looking for advice on how to easily accomplish the following task.
 I already have a Flex app that displays four thumbnail images in a
 vbox on the right side, and when I click on one, that image is
 displayed in a larger format within the same app (left of the vbox).

 What I'd like to do next is place a border/rectangle around the
 thumbnail, and have that border move down to the next thumbnail using
 a timer. So, I have a couple questions: (see the MTV header)

 1. Is it best to use a custom image class with border or is it better
 to use drawRect to place a rectangle over the mx:Image? Or use a
 TileList instead of vbox and make the timer automatically scroll
 through the thumbs?


 I basically want to accomplish something similar to the animated
 marquee/header on mtv.com (is the effect they use on the images
 mx.effects.move?)

 ...and I'm a beginner with any custom components and animation - so
 any clues/help would be appreciated.

 Thanks

Re: [flexcoders] trying to put a Degrafa BezierSpline on a Papervision3D Sphere...

You might need to use a degrafa surface rather than rendering into another
component. If that's not going to do it, I imagine you'll have to have
degrafa render into a bitmapData (or something along those lines) and add an
mx:image with that data set as the source.

Also there's a Degrafa list where you might get a better answer:

Re: [flexcoders] Newbie question: Completion Events or proxy binding for RemoteObject calls

 I'm working on an application where I build a tree (in actionscript
 buildtree()) where I add new leafs from data that is retieve from a
 remote call.

 Since the buildtree() function deals with the view - I have this coded
 in the view mxml. The tree is bound to a XMLListCollection which is
 updated by the buildtree() function after a remote value object is updated

 The remote RetrieveDataCommand successfully retrieves the data into a
 business value object.

 What is the correct Cairgorm method for triggering the builtree()
 function after the RetrieveDataCommand is complete?

 I don't want to pollute my Command logic with any specific calls to
 buildtree()

 Should I be adding RemoteCommandComplete events to all of my
 RemoteCommands? and then set the view logic to listen for them?

 I tried to set a Collection.COLLECTION_CHANGE listener on the Business
 Value object from my View logic. But it seems to fire before the
 ArrayCollection is complete.

 I also tried the BindUtils function to bind my buildtree() function to
 my value object,  but bindutils only seems to work with MX visual
 objects, not actionscript value objects.

 Any experts out there? I'm sure there must be a simple solution for this.

Re: [flexcoders] Re: why I can not dispatchEvent with creationComplete?

If you want to listen to events that are dispatched from Application, you
need to listen at either Application.application or (better) make them
bubble, and listen on the SystemManager.

  I'm having a similar issue. Event is dispatched (I can step through
  code and see it) but the event listener is never hearing it, and so
  the listener function is never being fired.
 
  How does one tell if the listener is ready or not? If you add the
  listener on the creationcomplete or initialize event of an mxml
  component, it should in theory be ready to fire, for the duration of
  the app, right? And if you're dispatching a custom event when an item
  is selected in a combobox, it should certainly work. What could be the
  reason for a 'deaf' event listener? :)

Re: [flexcoders] Re: flash.utils.Proxy -- Unable to compile.

If it's not marked dynamic, you'll always get an exception when you try to
dereference something that's not explicitly declared. If not, you've found a
compiler bug :) However, if you're casting to something that's marked
dynamic (such as Object, or *), it won't. And you can always use
foo[field] without a compiler warning.

Re: [flexcoders] Re: why I can not dispatchEvent with creationComplete?

When you do this:

mx:Canvas xmlns:mx=http://www.adobe.com/2006/mxml;
creationComplete=this.addEventListener(FoodEvent.FOOD_EVENT,
foodEventhandler)
borderStyle=solid borderColor=red borderThickness=3 x=300
y=300 width=200 height=200

You're listening for the FOOD_EVENT on your Canvas. If it doesn't bubble
up (bubbling is only upwards on the displaylist) to your canvas, you'll
never see it, so your Canvas would have to be a parent or ancestor of
Application. Change this:

creationComplete=this.addEventListener(FoodEvent.FOOD_EVENT,
foodEventhandler)

to this:

creationComplete=systemManager.addEventListener(FoodEvent.FOOD_EVENT,
foodEventhandler)

Re: [flexcoders] Generating Random key

Stupid ECMAScript... It'd be much more readable in Ruby/Lisp/Ioke/etc :)

  Heh, but if you're REALLY going for unreadable lines of code, you might as
 well go all the way:

 function repeat(n:Number, f:Function) : Array {
return n  1 ? repeat(n-1, f).concat(f()) : [f()];
 }

 function createUID():String {
return repeat(4, function(){ return repeat(3, function(){ return
 String(BCDFGHJKLMNPQRSTVWXYZ).substr(int(Math.random()*19), 1) }).join()
 }).join(-);
 }

   A quick take on it:

 function randomLetter() : String
 {
 const noVowels : String = BCDFGHJKLMNPQRSTVWXYZ;
 return noVowels.charAt(Math.round(Math.random() *
 (noVowels.length - 1)));
 }

 function repeat(n : Number, f : Function) : Array
 {
 return n  1 ? repeat(n-1, f).concat(f()) : [f()];
 }

 var result : String = repeat(4, function() : String {
 return repeat(3, randomLetter).join(); }).join(-);

  Hi Brendan
 makes sense to put the code :-), With the format I was looking for
 following code works perfectly for me, I am not sure thats the right way of
 coding but this is working for my purpose. I am pretty sure there can be far

   So what did you end up putting together?  Should post the code here

   Hi
 I need to work on a piece of code in which whenever user clicks on the
 button , the code should generate random 12 character key having all
 caps and no vowels in the format of XXX-XXX-XXX-XXX. Can anybody guide
 me in this direction. Is there any built in function for that or do I
 have to use my own logic for random generation in this specific case.
 Any help will be appreciated.
 Thanks
 Anuj

Re: [flexcoders] Generating Random key

...Although some features from JS1.7 / 1.8 would be a big step in the right
direction.
