[flexcoders] Drag and Drop question
Hello, How to Drag an Image A on the Image B. The image A replace the image B. And the image B come to replace the image A automatically. (There is a swapping). I use DragDropHandler and dragEnterHandler. Thank you, Christophe,
[flexcoders] Drag and Drop question
I am trying to implement drag and drop onto a tree. In the dropDrop
handler, I want to be able to deny the drop from happening, based on
which element of the tree is being dropped on.
// r is the visible index in the tree
var dropTarget:Tree = Tree(event.currentTarget);
var r:int = dropTarget.calculateDropIndex(event);
dstXmlTree.selectedIndex = r;
var node:XML = dstXmlTree.selectedItem as XML;
if (node.toXMLSting == whatever) {
// Allow drop -- HOW?
} else {
// Do NOT allow drop -- HOW?
}
How do I deny the drop?
thanks!
Re: [flexcoders] Drag and Drop question
I believe you're going to need to handle the drop events yourself and not
use the dropEnabled=true setting. When you do that, by default drop is
denied and you have to tell it to allow it, like in the dragEnter event.
For example:
private function dragEnterHandler(e:DragEvent):void
{
DragManager.acceptDragDrop(UIComponent(e.currentTarget));
DragManager.showFeedback(DragManager.COPY);
}

RE: [flexcoders] Drag and Drop question
I use the dropEnabled setting, but in all of the handlers, I call
event.preventDefault(); Then I test the source and target and call
DragManager.showFeedback(), DragManager.acceptDragDrop() conditionally
as required.

[flexcoders] Drag and Drop question
If i'm dragging an element from one tree to another. How do i get the updated xml of the tree i'm dragging off? For instance TREE 1 - Element 1 - Element 2 TREE 2 if i get the xml from tree 1 it would be something like root element label=Element 1 / element label=Element 2 / /root but if i drag the Element 1 into the TREE 2 i want to get the xml without the Element 1, without that node. i'm trying to get it creating a handler for dragDrop attribute on the Tree 2, but everytime i get it the items are not updated. Anyone know how to get the updated xml that tree 1 will have after i drop the element? Please... this is killing me =/ Thanks
Re: [flexcoders] Drag and Drop question
I'm fairly certain that there's no voodoo to automatically delete nodes from your XML, you need to do that yourself in your drop handler. -J On Thu, May 1, 2008 at 4:36 PM, Rafael Faria [EMAIL PROTECTED] wrote: If i'm dragging an element from one tree to another.

Re: [flexcoders] Drag and drop question
Still doesn't work, would it be too much to ask you to post that code to draw
bitmap data onto UIComponent? I tried to implment that idea with following
code:
public function dragItMain(event:MouseEvent):void{
// Get the drag initiator component from the event object.
var dragInitiator:UIComponent = event.currentTarget as
UIComponent;
// Create a DragSource object.
var dragSource:DragSource = new DragSource();
dragSource.addData(dragInitiator, main);
var target:UIComponent = event.curentTarget as UIComponent;
var bitmapData:BitmapData = new BitmapData(
Math.round(target.width /
target.scaleX),
Math.round(target.height /
target.scaleY),
false);
bitmapData.draw(target);
var bitmap:Bitmap = new Bitmap(bitmapData);
var bitmapHolder:UIComponent = new UIComponent();
bitmapHolder.addChild(bitmap);
// Call the DragManager doDrag() method to start the drag.
DragManager.doDrag(dragInitiator, dragSource, event,
bitmapHolder);
}
But all i got is the following error:
ArgumentError: Error #2015: Invalid BitmapData.
at flash.display::BitmapData$iinit()

Definitely not, width and height of the image is under 1000px so i guess
that's not the problem?

You can drag-drop anything. var dragItems = event.dragSource.dataForFormat(items); and dragItems is always returning undefined. Where are you adding the items to the DataSource? You should be having something like this when the drag starts: var ds:DragSource = new DragSource(); ds.addData([button, text], items); DragManager.doDrag(this, ds, MyDragProxy); Now dataForFormat(items) will return the button and text objects.
