Start Drag filter

Troubleshooting gui
1

Hi,



why is it not possible to add a filter to a DraggableControl so that one can be notified on starting drag

i need to know when it starts

so far i can only add an accept filter

Code:
dropable.addFilter(new DroppableDropFilter() { public boolean accept(Droppable drpbl, Draggable drgbl, Droppable drpbl1) { // drgbl.getElement().findElementByName("image").setVisible(false); box.setCullHint(Spatial.CullHint.Always); currentDraggedObject=false; return true; }

thx

I’m not sure what you mean by “filter” to be notified when a drag operation starts.



Start drag operation will be published as a DraggableStartDragEvent on the EventBus as explained in the Nifty wiki: <a href=‘http://sourceforge.net/apps/mediawiki/nifty-gui/index.php?title=Standard_Controls_Drag’n’Drop#EventBus_Notification’>http://sourceforge.net/apps/mediawiki/nifty-gui/index.php?title=Standard_Controls_Drag’n’Drop#EventBus_Notification



Hope that helps,

void

EventBus Notifications explained in the Nifty Wiki should help, I think?

It is working but there is no way to have a callback while the mouse is dragging
i tried to add onMouseOver but it is not called during a dragdrop operation :(
