[flexcoders] ArrayCollection.setItemAt() triggering a new instance of itemRenderer class
Tracy, Thanks for the info. Yeah, that makes sense. Initially I was thinking that I could reuse images, textfields, etc., which I sometimes can, but I can't count on the fact that they'll be there. Sorry about hijacking the thread. My mistake. Thanks, Brandon
[flexcoders] ArrayCollection.setItemAt() triggering a new instance of itemRenderer class
Hello all, I'm using an array collection as a data provider for a list component with a custom itemRenderer. If I use arrayCollection.addItemAt(), a new instance of the itemRenderer class is created. If I use arrayCollection.setItemAt, the current instance for that particular item is updated, meaning the data property is set. This all seems normal. It seems that the first time I run setItemAt(), another instance of the itemRender class is created in it's place, despite the index of the item not changing. (It's just an icon or text, etc.) Every subsequent time I call setItemAt(), the data property is updated without creating a new instance, but the first time, it's as if I'm adding an item to the list in the same location. It breaks down as there are instance vars in the itemRenderer I'm depending on. Thanks, Brandon
RE: [flexcoders] RemoveChild not removing instance from memory
The only way I was able to have GC remove these objects was to remove their children first - radio buttons, checkboxes, etc., then remove them. Seems odd but it works. Thanks for your help.

RE: [flexcoders] Flash OCX Error
Alex, I've been doing some testing with this app in trying to recreate this ocx error. I've monitored both memory consumption and cpu. The browser memory never gets above 90mb, event after a few hours of running. The cpu spikes a bit when resizing and interacting with the various lists, but I can't recreate the error. You mentioned that this error is usually caused by a stack overflow or memory consumption. Can I assume that the browser memory is an accurate reading of the memory used by the Flash Player, or is there internal Flash memory which could be maxed out, unrelated to browser memory?

If you start with ListItemRenderer, you definitely have to kill the code that will set the textfield’s text property during the handshake with the List via the data/listData properties. But once you do that, it should measure correctly. I’d probably make a copy of ListItemRenderer instead of subclassing, and replace setting .text with setting .htmlText The issue is not labelFunction, it just returns a string.

[flexcoders] Issues with Full-Screen Video
I've got a Video object inside of a custom VideoDisplay component inside of a larger UI with other components. The Video object, once resized, ends up being 250 by 180. My full-screen toggle button gets the dimensions and location of the Video object, in relation to the parentApplication. I then set the fullSreenSourceRect to a new Rectangle with the same dimensions and location. When the video goes full-screen, it looks fine for a second, then when the "Press Esc to Exit" message appears, the entire bottom half of the source rectangle area (the area below the message) dissapears. This can be fixed by setting the scaleMode to StageScaleMode.EXACT_FIT, but then when I exit from full-screen mode, my entire UI is sized incorrectly. Thanks in advance, Brandon Code: var boundsObject:Rectangle = videoDisplay.subscribedLiveVideo.getBounds(this.parentApplication as DisplayObject); var x:Number = boundsObject.x; var y:Number = boundsObject.y; var w:Number = boundsObject.width; var h:Number = boundsObject.height; this.parentApplication.stage.fullScreenSourceRect = new Rectangle(x, y, w, h); //this.parentApplication.stage.scaleMode = StageScaleMode.EXACT_FIT; this.parentApplication.stage.addEventListener(FullScreenEvent.FULL_SCREEN, fullScreenHandler); this.parentApplication.stage.displayState = StageDisplayState.FULL_SCREEN;
Re: [flexcoders] LocalConnection
I ended up getting this to work. Initially, I was waiting for the "onLoadComplete" event before trying to interact with a loaded movie via a moviecliploader in the Flash 8 proxy file. I changed it so that it waits for the "onLoadInit" event, which was happening after the "onLoadComplete" event, at least when I tested it locally. So, if I wait for the "onLoadInit" event via the moviecliploader, and then call functions, I'm good.

Hi Brandon,
Use the following to set focus for the textField's instance of UITextField:
var textField:UITextFie ld = new UITextField( );
textField.type = "input";
textField.autoSize = TextFieldAutoSize. LEFT;
textField.multiline = true;
textField.wordWrap = false;
textField.border = false;
myContainer. addChild( textField)
textField.setFocus( textField) ;
Notice, that first you have to add textField to the DisplayChildList
of corresponding container via addChild and only then you can call
"setFocus" on it.

[flexcoders] Placing cursor inside UITextField
I'm creating some Input UITextField instances dynamically, and then trying to place the cursor inside. Can't seem to get it working. var textField:UITextField = new UITextField(); textField.type = "input"; textField.autoSize = TextFieldAutoSize.LEFT; textField.multiline = true; textField.wordWrap = false; textField.border = false; stage.focus = textField; It seems to get the focus, but doesn't put the cursor inside. Can't just start typing. Also, textField.setFocus() doesn't work. Thanks, Brandon
Re: [flexcoders] Re: referencing embedded images inside AdvancedDataGridGroupItemRenderer
Amy, thanks. The only difference is that I'm assigning the iconFunction in AS
like so:
adg.iconFunction = myFunction;
private function myFunction(item:Object):Class {
trace("made it this far!");
}
I get nothing. Let me look into it further. Thanks for all your help.
Brandon

The iconFunction is not ignored by the _Advanced_ Data Grid. I can
tell you this, because I use it successfully in a project I just
finished.
here's a snippet of my code
//show appropriate menu icon based on state ond
//nature of item
private function menuIcon(item: Object):Class{
if (item is TaskUID){
var taskItem:TaskUID = item as
TaskUID;
switch (taskItem.isComplet e) {
case Task.NOT_STARTED:
return icnEmpty;
case Task.STARTED:
return icnStarted;
case Task.COMPLETE:
return icnComplete;
}
} else if (item is MenuContainer) {
var containerItem: MenuContainer =
item as MenuContainer;
switch (containerItem. runMode) {
case 'Normal':
return icnNormal;
case 'Review':
return icnReview;
case 'Analysis':
return icnAnalysis;
}
}
return null;
}
The MXML looks like this:
Re: [flexcoders] Re: referencing embedded images inside AdvancedDataGridGroupItemRenderer
Amy, I can't seem to get the iconFunction to work with the ADG. As per the docs, "This property is ignored by data grid controls." It compiles but it IS in fact ignored. Do you use the groupIconFunction?

Right now I'm using a switch statement which tests "value.icon" and returns the proper embedded image class name. I'm confused as to why I can't convert the String the "image1" to Class image1. Seems easy enough, but nothing works. That's what iconFunctions are for. But you could try img.source = this[value.icon] ; HTH; Amy

It seems easier this way since I'm using a dataprovider which is updated often,
changing the icon. Right now I'm using a switch statement which tests

Why not just use an iconFunction?

[flexcoders] referencing embedded images inside AdvancedDataGridGroupItemRenderer
I've embedded some images like so:
[Embed(source="images/image1.png")]
private var image1:Class;
[Embed(source="images/image2.png")]
private var image2:Class;
I can't seem to reference these class names from a String like so:
override public function set data(value:Object):void {
img = new Image;
img.source = getDefinitionByName(value.icon) as Class;
//getDefinitionByName is part of flash.utils package
img.width = 22;
img.height = 22;
addChild(img);
}
I also tried the following:
value.icon as Class
Class(value.icon)
Thanks,
Brandon
[flexcoders] comboBox.percentWidth ignored?
I've got a comboBox inside of a HBox. I can see in the docs that a comboBox, by default, takes on the width of the largest title. Setting the width via comboBox.width or comboBox.setActualSize set's it to the correct size, but setting the percentWidth property seems to be ignored and the comboBox is way to wide for the HBox. Am I missing something? Thanks, Brandon

Re: [flexcoders] Re: AdvancedDataGridRendererProvider.renderer
Thanks Amy. This helped. It actually ends up looking like this:
iconRendererProvider.renderer = new ClassFactory(myClass);
The other issue I'm having is displaying images since
AdvancedDataGridItemRenderer extends UITextField. Do I have to extend
AdvancedDataGridGroupItemRenderer in order to display images? The DataGrid
component doesn't seem to have this option at all.
Thanks again,
Brandon

[flexcoders] AdvancedDataGridRendererProvider.renderer
I'm trying to set the "renderer" property of an AdvancedDataGridRendererProvider in AS. var iconRendererProvider:AdvancedDataGridRendererProvider = new AdvancedDataGridRendererProvider; iconRendererProvider.columnIndex = 0; iconRendererProvider.columnSpan = 1; iconRendererProvider.dataField = "icon"; iconRendererProvider.renderer = myClass; myClass extends AdvancedDataGridItemRenderer and overrides the data function.

I've created some custom components by extending UIComponent. I've implemented createChildren, commitProperties, measure, and updateDisplayList. I can resize the custom UIComponents using any number of methods: constraints, CSS, etc. They resize no problem. But if I try to size a child of that custom component, no width or height is assigned, unless I use an explicit setActualSize. For example: My custom component (Content) has been added to a canvas. The component is sized using width and height properties: var content:Content = new Content; content.width = 800; content.height = 800; addChild(content) ; In content, in createChildren, I create an instance of the Image component. var container:Image = new Image; container.scaleCont ent = false; addChild(container) ; I try to do this: container.percentWi dth = 100; container.percentHe ight = 100; But nothing. I can only seem to resize this inside updateDisplayList like so: container.setActual Size(unscaledWid th, unscaledHeight) ; Thanks, Brandon
