Hallo,
gibt es eine Möglichkeit, den Hintergrund des Enginefensters transparent zu setzen so dass ich nur meine bmap des Panels (abgerundete Ecken) sehe?

Hi, try video_border or video_window (with the no border option).

Hi, i have tried. With video_window I have no borders, but a black rectangle. video_border is the same, a black color. What I want is only the panel background image with round corners without the black corners of the engine window... thats not possible to disable the background color of the engine window?

Check GStudio8/samples/digital.c!

Thank you, it works now I has a 32bit png file with an alpha channel and that was the problem.
