I am developing an application in which when I start the Drag operation using the
DragManager.doDrag(dragInitiator, ds, event,
imageProxy, 0, 0,1.00);
, I assign imageProxy as a new image to be the drag image - setting its style in the MouseEvent handler that initiates this drag operation.
Where dragInitiator is a draggable container.
In my implementation I need the imageProxy to change its source i.e. whenever I have my drag object over certain container which has dragEnter listener to facilitate drag,
the proxy image should re-size itself and change its source. This change in proxy image should be done without cancel/completing the drag operation.
As far as the online browse goes all I can find is that one cannot change the drag proxy image after the drag operation is started and can only cancel the current drag and initiate a new one
with the required new image proxy.
Note: this is a drog-n-drag for the non-list based control
I don't think you can change the display object that is the proxy image, but you might be able to change the children of that display object.
