[flexcoders] Re: Conditional formatting of tree node labels

[barry.beattie]

Ivo, did you find a solution?

the tree controls' "labelFunction" (instead of "labelField") could be
an easy way out to conditionally modify the label's condition0

just a quick suggestion

private function treeLabel( item:Object ) : String
{
 var node:XML = XML(item);
 var labelText:String;
 // choose what to use for label
 // TODO: replace hard-coded node name with [if not hasChildren]
 if( node.localName() == "question")
 {
labelText = String([EMAIL PROTECTED]);
 }
 else 
 {
labelText = String([EMAIL PROTECTED]);
 }
 if (labelText.length > 30) // too long
 {
labelText = labelText.substr(0,30) + "...";
 } 
 return labelText;
}

[ivo]

Thanks for the response Barry. I was away & just now
catching up on email.

Turns out I did not have to do:

var treeListData:TreeListData =
TreeListData(super.listData);
if(treeListData.isDirty){
this.label.setStyle('fontStyle', 'italic');
}

but just:

var treeListData:TreeListData =
TreeListData(super.listData);
if(treeListData.isDirty){
setStyle('fontStyle', 'italic');
}

I had one of those doh moments when I noticed it.

Regards,

Ivo
