Hey Osman!
Sorry for my imprecise question 😅
In the TouchGFX Designer you can select a skin which is used
as a static background image for a running simulation. I wanted to
change this image while running the simulation if e.g. a button is
clicked. Found the solution for myself:
I have extended the HALSDL2 class with a custom loadSkin()-function,
where i pass the name of a skin image. I just have to specify the desired
images i want to use in the Makefile. When setting the first skin, it is necessary
to call the recreateWindow()-function. When changing the skin a second, third, ... time
you can just call the SDL_SetWindowShape()-function.
