Dear Mr. Petasis,
thank you very much for your help. Indeed there is a depth value of 8.
If anyone is interested, my problem was that my added pixmap buttons
were all images rendered with povray so they all required 256 colours
which of course exhausted the colour map. Since the buttons are small
there is no need to have 256 colours. I then drastically reduced the
amount of colours with ImageMagick's convert program and this solved my
problem. ( convert -colors 4 Stop_pixmap.xpm Stop_pixmap.xpm ). There
is of course a small loss in quality but I can live with that.
Thanks again for the hint. I appreciate it.
