Further info on this,
If I was to create a window, call some draw functions, create a new window,
draw some new functions again, this is fine, but I wish to be able to create
all windows at the top of my program, but if I do this, the new windows will
create
and map fine, but when it comes to checking the clip region before I draw,
the
clipresult gets set to false.
I see in the demo code in slider.c that this should be quite possible, but
despite
having identical set up to this, I still have this problem.
If anyone can help I'd be most grateful.
