Hi everyone!
Based on some posts to this list I've created a Border class, that draws ba
border with title around widgets. So far so good.
My problem is, when I tray to change the borders color, only the top line and
the bottom line are being ignored. They simply does not change the color and I
can
not figure out where the bug is....
Perhaps someone could give me a hint what is wrong?!
Best,
Joern
