[flexcoders] Is there an isset() in Actionscript 3? (Or an exists())
If I have an hash (object) like this:
var o:Object = new Object();
o['blahblah'];
How do I test if there exists an o['wwwrgwr']?
I had a situation where I set something to a string:
o['blahblah']='wefwefw';
and then later tried:
if (o['blahblah']['something']) {
}
and I got:
Property value not found on String
How do I test if there is exists an o['blahblah']['something'] ?
thanks

[flexcoders] Loading an external swf screws up the layout (f2)
Anyone who tries to use the Loader class to load a large (in pixels) Flash 7/8 swf into a Flex app would probably run into this. But I couldn't find it in the archives... If you load an external Flash 8 swf into a Flex 2 app, with the Loader class, it will spill out of whatever container you put it in. Really looks like a bug. In other words, say you want to load a large (say 1000 pixel) swf file, into an HBox that's 100 px wide. If you put the Loader into a UIComponent, and then put that UIComponent into an HBox, and the width of the swf that you loaded is larger than the width of the HBox, the swf will just spill over the edges of the HBox. And spill over pretty much anything else in the Flex app too, while it's spilling. What do I do here? Yahoo! Groups Sponsor ~-- See what's inside the new Yahoo!

tree.labelField=@label;
var xml:XML = node
node label=Something
node label=child one/

/node;

I've tried:
tree.expandItem( XML(this._tree.dataProvider).node[0],true);
tree.expandItem( XML(XML(this._tree.dataProvider).node[0]),true);
tree.expandItem( XML(this._tree.dataProvider).elements('node') ,true);
tree.expandItem(
XML(this._tree.dataProvider).elements('node').valueOf() ,true);
And I've tried tree.invalidateList(); afterwards, doesn't help. This
might be a flex bug. Has anyone programmatically selected a tree node
*without* using something like tree.selectedItem.parent?

If you want a button for one column of a DataGrid, you can do something
like
To use just the default drop-in button:
mx:DataGridColumn itemRenderer=mx.controls.Button ...
Or, you can create a custom component that subclasses the Button class
so that you can define what type of events happen when you click the
button. (This is probably more likely). So, you would then have
something like:
mx:DataGridColumn itemRenderer=MyButton ...
where MyButton.as looks something like -
public class MyButton extends Button

Just two- an outer TabNavigator and, on one of it's tab's canvas's, an
inner one. Sounds simple right?
I reduced it to a smaller reproducable version of the error, here is
what I'm doing in my Application:
var t:TabNavigator = new TabNavigator();
t.width=800;
t.height=600;
t.creationPolicy='all'; //tried this to fix
var tab1:Canvas = new Canvas();
tab1.label='Welcome';
t.addChild(tab1);
var tab2:Canvas = new Canvas();
tab2.label='Hello';
t.addChild(tab2);
var tn2:TabNavigator = new TabNavigator();
tn2.creationPolicy='all';
var tn2tab1:Canvas = new Canvas();
tn2tab1.label='wefwe';
tn2.addChild(tn2tab1);
var tn2tab2:Canvas = new Canvas();
tn2tab2.label='wefwe333';
tn2.addChild(tn2tab2);
tab1.addChild(tn2);
this.addChild(t);
The tabs display fine initially, and then here is the exception I get
when I click on any tab (either on the inner tabnavigator or the outer
one):
TypeError: Error #1009: null has no properties.

[flexcoders] Mutiline LinkButton? (Flex 2)
Can I make a LinkButton that line wraps rather than pushing out the Box it's in (or doing an ellipsis), if it's text is too wide? In other words, the behavior you'd expect if it was an html hyperlink... Also, can I do hypertext in Flex? Like, a text field with some of the words as hyperlinks? And can I trap events when those links are clicked? -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com SPONSORED LINKS Web site design development Computer software development Software design and development Macromedia flex Software development best practice YAHOO!

[flexcoders] Flex 2: How do I make a List that has different heights?
If you make a List control, and you put some options in it, and one of your options is long and happens to wrap, it doesn't wrap the text! It just cuts off the end of the text. How do I make it wrap?? I even tried making a custom IDropInListItemRenderer. If I set the height differently for some but not for others, then the highlighting gets messed up. Apparently the size of the blue highlighter bar has to be the same for all??! Am I the only one with this problem? Anyone else made a List with a long text entry? -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com SPONSORED LINKS Web site design development Computer software development Software design and development Macromedia flex Software development best practice YAHOO!

[flexcoders] How to programmatically make a custom ListItemRender?
I'm trying to make a custom ListItemRenderer in Actionscript. I was
able to make it display the list correctly, but when I click on
anything in the list, I get this error:
TypeError: Error #1009: null has no properties.
at
mx.controls::List/drawItem()[C:\dev\beta2\sdk\frameworks\mx\controls\List.as:1416]

mx.controls::List/mouseDownHandler()[C:\dev\beta2\sdk\frameworks\mx\controls\List.as:1801]
Every function in that call stack is not in the documentation.
My hello worldish custom listitemrenderer so far is:
public class CustomItemRenderer extends HBox implements IFactory,
IListItemRenderer {
public var thelabel:Label;
public function CustomItemRenderer() {
super();
this.thelabel=new Label();
this.thelabel.percentWidth=100;
this.addChild(this.thelabel);
}
public function newInstance():* {
return new CustomItemRenderer();
}
public override function get data():Object {
return super.data;
}
public override function set data(value:Object):void {
this.thelabel.text=value['label'];
super.data="">
dispatchEvent(new FlexEvent(FlexEvent.DATA_CHANGE));
}
}
I also tried with IDropInListItemRenderer, and I get the same error.
Here is my instantiation.
var mylist:List = new List();
mylist.dataProvider=this.myarraycollection;
mylist.itemRenderer=new CustomItemRenderer();
