Thank you for the information.
In my project i use WPF based interactors that are gaze aware. Every interactor is a WPF window that is being created by the mainwindow. It works fine but i want to set the Window Style to WS_EX_LAYERED and WS_EX_TRANSPARENT. And here a strange behavior occurs. The interactors only work when the main window is next to them. I can’t find a solution for that.
That’s why i tried it with virtual windows. It works somehow but it behaves like not calibrated.
All in all i would like to go on with WPF because it is much more flexible and easier to use. Maybe i should find a different concept than “for every interactor a window”
Kind regards
