I have a upp application. window is created using 3d party manager. I am interested in catching keyboard/mouse by upp functions(getcapslock, scanninh keyboard etc) and to define callbacks for keypress, releases etc. is it possible some common way ? (I know uncommon ways well )
What is 3rd party manager?
Anyway, callbacks are independent of GUI. Perhaps the way to go is to create your own encapsulation / interface. Alternatively, use Ctrl interfaces without U++ GUI.
