Hello,
there seems to be a problem (or at least I am having this problem) with
drag & drop involving virtual widgets.
The current architecture assumes that it is enough to store the
sourceWidget and the destinationWidget during the drag session. However,
with virtual widgets this is not enough - we need to store the internal
information on what node/row/cell etc. has been dragged.
Of course, we can send it with the drag event during dragStart:
myVirtualTree.addEventHandler("dragStart",function(event){
// get drag source
node = this.getDataModel().getSelectedNodes()[0];
if ( node && node.type =="staffschedule.types.Person" )
{
event.addData(node.type, node);
event.addAction("move");
event.startDrag();
}
}
but if I use the "supportsDrop" method on the destination widget, I have
no access to the event data, because the dragCache object that is sent
to the supportsDrop function does not contain the drag data. So I am
left to attaching the data to the source widget and retrieving it
manually inside the supportsDrop function. Or is there a way to get the
drag data through qx.event.handler.DragAndDropHandler ?
Thanks,
Christian
