Re: [Vala] Gtk Custom widget: drawing with "gtk theme" colours

[Harry Van Haaren <harryhaaren gmail com>]

Cheers for the XFCE link, didnt know they were doing tut's these days!

I got the following vala code to work:

unowned Gtk.Style style = this.get_style();
// color.<x>  is a uint16: divide by 65535.0 to get 0-1 range
Gdk.Color color = style.bg[0];
cr.set_source_rgb(color.red/65535.0, color.green/65535.0,
color.blue/65535.0);

probably not the nicest code ever, but it gets the job done.

Gdk.cairo_set_source_color(some_cairo_context, some_gdk_color);   // taken
from the XFCE tutorial

That's a nice convenience function, but I dont really like the non-OOP
style...
Each to their own sure!
