i’ve been playing around with dgui for a while and thought i might post this, maybe someone has some improvement idea’s.
it’s far from being completed, i’d like to put that into a class to make windows instanceable. another problem is that the 0/0 point inside the window is still at the left bottom point (scrolling problem)
changed:
07.09.2008: updated the code (is not instanceable, having some problems with button textures)

x=base.mouseWatcherNode.getMouseX()

# the mouse position is read relative to render2d, so set it accordingly
aspect2dMouseNode.setPos( render2d, x, 0, y )
