How to set the background color of a pygtk window

Question

I am trying to set the background color for a pyGtk window which has a single DrawingArea widget. With this code I always get a random color everytime I launch the script:

widget = gtk.DrawingArea()
widget.show()
window = gtk.Window()
window.add(widget)
col = gtk.gdk.Color('#010')
window.present()
widget.window.set_background(col)
window.connect('delete-event', gtk.main_quit)
gtk.main()

I also tried using widget.modify_bg(gtk.STATE_NORMAL, col) instead of the set_background line, and I always get a black background.

What am I missing?

Ok, it seems like I was struggling too much with other things, and I didn't realize that I set the test color to #010, which is, obviously, almost black. Using modify_bg works, just remember to set a reasonable color ;)

This is the working code:

widget = gtk.DrawingArea()
widget.show()
window = gtk.Window()
window.add(widget)
col = gtk.gdk.Color('#0f0')
window.present()
widget.modify_bg(gtk.STATE_NORMAL, col)
window.connect('delete-event', gtk.main_quit)
gtk.main()

By the way, does anybody know why widget.window.set_background() sets a random color?

Using "import gi.repository" I had to use gtk.StateType.NORMAL instead of gtk.STATE_NORMAL – rocky Jun 30 '15 at 03:44

`modify_bg` as well as `override_background_color` are now deprecated, if I understood that correctly. – Nicolai Weitkemper Aug 21 '20 at 21:28
