I'm trying to use override_background_color on some GTK3 widgets but they still showing up with the default background color.

  • Can you post the code that you used in the end? – Mendhak Jul 7 '12 at 21:24
  • I"ve dropped it because I didn't have the time. Will try it later. – int_ua Jul 8 '12 at 8:54
  • I managed to do it here by using CSS in the GTK3 widget. – Mendhak Jul 22 '12 at 7:51

GTK+ 1.2

  GtkRcStyle *rc_style;
  GdkColor color;

  color.red = 65535;
  color.green = 0;
  color.blue = 0;

  rc_style = gtk_rc_style_new();

  rc_style->bg[GTK_STATE_NORMAL] = color;

  rc_style->color_flags[GTK_STATE_NORMAL] |= GTK_RC_BG;

  gtk_widget_modify_style (widget, rc_style);

  gtk_rc_style_unref (rc_style);

GTK+ 2.24

Using the GDK Library:

GtkWidget *widget; //your widget

  GdkColor color; 

  gdk_color_parse ("red", &color); //setting a color - you can also use RGB

  gtk_widget_modify_bg(widget, GTK_STATE_NORMAL, &color); //modifying the background color of the widget

Full reference about GdkColor can be found at GNOME'S Dev Documentation.

GTK 3.0

For gtk+3 you can use gtk_css_provider() .Full tutorials and examples can be found at the GTK+ Forums.

  • I've tried it first but in python there was no gdk.color_parse() function IIRC. Let me re-check... – int_ua Jun 29 '12 at 13:47
  • i am not familiar with pygtk but you can take a look here pygtk.org/docs/pygtk/class-gdkcolor.html – dlin Jun 29 '12 at 13:52
  • besides: Warning gtk_widget_modify_bg has been deprecated since version 3.0 and should not be used in newly-written code. Use gtk_widget_override_background_color() instead – int_ua Jun 29 '12 at 13:54
  • im still using GTK+ 2.24.Can you edit your post with the code which you use to change the background color?that would help – dlin Jun 29 '12 at 13:57

    In python you can do something like: [your widget].override_background_color(Gtk.StateFlags.NORMAL,Gdk.RGBA(1.0,0.0,0.0,1)) or [your widget].modify_bg(Gtk.StateFlags.NORMAL,Gdk.color_parse("red")) – AndAC Jun 29 '12 at 16:13
