GdkGC::foreground
Access: Read Write
Type: GdkColor
This looks so straightforward, and isn't. GdkGC
objects are so far down in the evolutionary scale that they don't have
an associated colormap. If you try to apply color directly, any color
will be returned as a muddy brown.
The way around this is to borrow an existing
GdkColormap and allocate a color from there.
You can use gdk::colormap_get_system() to do this,
or you can access the colormap in a GdkWindow.
The syntax is:
$gc->foreground = $colormap->alloc('red');
As with the GdkColor constructor, you could use
'#FF0000' or 65535, 0, 0 in place
of 'red', but not 1.0, 0.0. 0.0.
