thanx david, this also works for me, but does anybody now a "nicer" solution?

the solution of david needs for each column a second column to specify
whether the foreground_gdk-color shall be used...

in my application i have a big database-result-set to show, and i want
the "NULL"-values to be marked with a different color.

i could have very much columns and i would need a bool-model-column for each
view-column... i don't like this idea very much, but i will use it, because
i dont know how to make it better...

thanks!
