Daniel,
I tried this.
var draggedImage:Image = event.draggedItem as Image;
var dropCanvas:Canvas = event.currentTarget as Canvas;
var bmpData:BitmapData =
Bitmap(draggedImage.content).bitmapData;
var bitmap:Bitmap = new Bitmap(bmpData);
var newImage:Image = new Image();
newImage.source = bitmap;
newImage.x = dropCanvas.mouseX;
newImage.y = dropCanvas.mouseY;
dropCanvas.addChild(newImage);
I get this error:
TypeError: Error #1009: Cannot access a property or method of a null
object reference.
The error trace points to "draggedImage.content". Looks like
draggedImage is null.
I was trying out a few other things to see what formats are available
from DragSource
var ds:DragSource = event.dragSource;
var formatArray:Array = ds.formats;
for (var i:String in formatArray)
{
Alert.show(formatArray[i]);
}
The Alert shows "items" as the value in the formatArray.
Not sure how to get hold of the Image. The source as i said was an
mx:Object array which has icon attribute using a embed image.
Let me know if i can try anything else. Thanks
