Imagine u have a set of images that u can drag and drop onto a canvas. In place of these images i want buttons. I tried but when i drag and drop, the button disappears from the list. Please let me know how i can just replicate the button in the list onto the canvas when i drag and drop. Please check my code below: public function dragButton(e:MouseEvent):void { if(e.buttonDown) { var button:Button = e.currentTarget as Button; var buttonProxy:Button = new Button(); buttonProxy.width = button.width; buttonProxy.height = button.height; var dragSource:DragSource = new DragSource(); dragSource.addData(button, 'button'); DragManager.doDrag(button, dragSource, e); } } public function dragEnter(event:DragEvent): void { var target:Canvas = event.currentTarget as Canvas; if (event.dragSource.hasFormat('button')/* && target.getChildren().length == 0 */) { DragManager.acceptDragDrop(target); DragManager.showFeedback(DragManager.COPY); } } public function dragDrop(event:DragEvent): void { var target:Canvas = event.currentTarget as Canvas; var button:Button = event.dragSource.dataForFormat('button') as Button; button.x = event.localX; button.y = event.localY; networkStage.addChild(button); } Hi,
