Flex Button Drag and Drop with X and Y Co-ordinate :-
In this tutorial you can drag and drop for button with x and y co-ordinate or move one place to another in container. In this tutorial we can explain how to use Drag Manager, Drag Source, Drag Event . we can do that process manually through action script function.
Example:-
<?xml version="1.0"?>
<!-- dragdrop\DandDImage.mxml -->
<mx:Application
xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Script><![CDATA[
import mx.managers.DragManager; import mx.core.DragSource; import mx.events.DragEvent; import flash.events.MouseEvent; private function mouseMoveHandler(event:MouseEvent):void{
var dragInitiator:Button=Button(event.currentTarget); var dragSource:DragSource = new DragSource();dragSource.addData(dragInitiator,
"button");DragManager.doDrag(dragInitiator, dragSource, event);
}
private function dragEnterHandler(event:DragEvent):void { if (event.dragSource.hasFormat("button")){
DragManager.acceptDragDrop(Canvas(event.currentTarget));
}
}
private function dragDropHandler(event:DragEvent):void {Button(event.dragInitiator).x =
Canvas(event.currentTarget).mouseX;
Button(event.dragInitiator).y =
Canvas(event.currentTarget).mouseY;
}
]]>
</mx:Script> <mx:Canvas id="myCanvas"width="
100%" height="100%"borderStyle="
