You have to set widget style.

	GtkStyle* style = gtk_style_copy (gtk_widget_get_style (
						  GTK_WIDGET (m_widget)));
	GdkColor* bg = &style->base[0];

	bg->red   = background->red;
	bg->green = background->green;
	bg->blue  = background->blue;

	gtk_widget_set_style (GTK_WIDGET (m_widget), style);
	gtk_style_unref (style);

However, I don't know what you have to do to change widget's style
at run-time. There got to be a way to tell Gtk+ to redraw widget.
If you find out, let me know too.
