Hi Everyone, I'm having a really annoying problem that I can't seem to solve. I have a custom built tree component (built from a List) using the Flex 4 SDK. I need to drag an item from this list into another custom List component (the only customization here is the Skin).
I can get the tree items to drag just fine. However, I cannot get the second list to accept the dragDrop. I have set dragEnabled and dropEnabled to true. When I use "this as IUIComponent" as the target in DragManager.acceptDragDrop, it does not work. I still see the cursor with the red X and the dragDrop event does not first. If I use the dragInitiator, or the dataGroup of the List, I see the correct "Copy" indicator but no dropEvent gets fired. I assume that's becuase I have not set the list as a valid drop target. I have tried this by listening on dragEnter and dragDrop events and also by overriding the dragEnterHandler and dragDropHandler on the list. Below is my code: /** @inheritDoc spark.components.List#dragEnterHandler **/ protected override function dragEnterHandler(e:DragEvent):void { if ( e.dragSource.hasFormat("presentationFromTree") ) { DragManager.acceptDragDrop(this as IUIComponent); DragManager.showFeedback(DragManager.COPY); } else { DragManager.showFeedback(DragManager.NONE); } } /** @inheritDoc spark.components.List#dragDropHandler **/ protected override function dragDropHandler(e:DragEvent):void { if ( e.dragSource.hasFormat("presentationFromTree") ) { // Handle the dropping of data from the fileManager tree var itemData:XML = XML(e.dragSource.dataForFormat("presentationFromTree")); handleDropFromTree(itemData); } } Any thoughts or ideas on how I can get this work? Many thanks in advance!
