I've been googling and asking for help for a while, but no success.
I've got a Canvas where some stuff is drawn, and a few buttons and comboboxes next to it, lined in a row under the drawing area. When I click on any of the comboboxes, part of the drop-down menu has to be rendered over canvas, but it is always behind it:
Why does this happen, and what can I do?
tnx in advance
