[gtkada] Set_Foreground

[Manuel Op de Coul]

It's not a label but a text entry as I said. I have no problem setting
the colour of labels.

Tried that too with Set_Rgb, no help. Please try it yourself, it's
only a few lines of code and I am almost convinced you will find the
same problem. It's a straightforward thing that worked in 1.2 and not
it 2.2.
