RE: [flexcoders] Drop Target indicator visibility issue

2010-09-03 Thread Philip Smith 

Still experiencing the drop indicator visibility issue.

This method handles the 'dragOver event (and is executing):

private function onDragOver(de:DragEvent):void
  {
de.preventDefault();

var owner:List = this.owner as List;

var dropLocal:DropLocation = 
owner.layout.calculateDropLocation(de);
trace (dropLocal);

owner.layout.showDropIndicator(dropLocal);
}

However, the drop indicator is not visible. I set a breakpoint in the code 
above and it appears the width of the drop indicator is 0...

Any ideas how to get this working?

Thanks.

The drop target indicator is not visible when dragging an ItemRenderer in a 
Spark List with the following implementation: ( note the 'dragOver handler' 
(with 'layout.showDropIndicator' behavior) is in the 'onDragOver' method below):



s:List itemRenderer=GroupItemRenderer

  dropEnabled=false

  useVirtualLayout=true

  width=100%

s:layout

s:HorizontalLayout  /

/s:layout

/s:List



GroupItemRenderer (referenced in the list above):



s:ItemRenderer autoDrawBackground=true

dragOver=onDragOver

dragDrop=onDragDrop(event),

dragEnter=this.onDragEnter(event)





fx:Script

![CDATA[

 private function onDragOver(de:DragEvent):void

{

de.preventDefault();

var owner:List = this.owner as List;



var dropLocal:DropLocation =   
owner.layout.calculateDropLocation(de);



owner.layout.showDropIndicator(dropLocal);



}



]]

/fx:Script



Any ideas on how to get this working? 



Thanks,

I think the dropIndicator gets its width/height in showDropIndicator.  I think 
there is default drag/drop code in List.  Compare your override against that 
code.
