Hello Members,
I am new to Flex and this is my first post to FUG. I am using dragdrop
in TileList having big boxes as TileList itemrenders.
I have defined one invisible drop target to accept these tilelist
boxes so user can remove items from tilelist with dragging them on
above invisible target.
In accept DragDrop function I am facing problem with Drag Event as it
extends MouseEvent. If user want to remove big box object the target
is accepting same if the mouse cursor is on the target.
If user picks box from one side and dragged it over the invisible
target event entering this big box more than half way I am not able to
catch "DragEvent" as mouse pointer is at the bottom side of box object
and not
over the drop target.
Is there any way to define co-ordinates to the mouse while dragging,
so when dragged object touches to the target it should be acceptable.
Here is my sample code -
<mx:TileList dragEnabled="true" id="tileList"
dataProvider="{TileListdp}" dropEnabled="true"
doubleClick="showPopup(event)"
itemRenderer="com.servient.renderers.BigBoxItemRenderer"
dragMoveEnabled="true"
rowHeight="150" columnWidth="400" width="100%"
height="100%">
</mx:TileList>
// invisible Trash Can where use is dragging object to remove
<mx:Image dragDrop="item_dragDrop(event);"
dragEnter="item_dragEnter(event);" height="42" width="42"
source="@Embed('images/trash-small.png')" />
//Drag Drop Event Handling
private function item_dragEnter(evt:DragEvent):void {
//Alert.show("In DragEnter");
var obj:IUIComponent = evt.currentTarget as UIComponent;
DragManager.acceptDragDrop(obj);
DragManager.showFeedback( DragManager.LINK );
}
private function item_dragDrop(evt:DragEvent):void {
//Alert.show("Here in DragDrop");
var item:Object = tileList.selectedItem;
var idx:int = TileListdp.getItemIndex(item);
TileListdp.removeItemAt(idx);
}
Thanks in advance!
