[Glade-users] gtk_label_set_text fails, but not gtk_label_get_text

[stuart.gilbert at gmail.com (Stuart Gilbert)]

Hello.

I've got an application with a label and 3 buttons. When I click one of the
buttons I want the label text to change. gtk_label_set_text doesn't give me
any errors, but it also doesn't change the text at all.

gtk_label_get_text works fine when I put it in before the set_text, and then
prints a blank line if I put it after the set_text.

I get no errors or warnings during compilation with the following line: gcc
famulus.c -o fam `pkg-config gtk+-2.0 --cflags --libs` `pkg-config
libglade-2.0 --cflags --libs` -export-dynamic

I'll paste my code below because it's not very long.

Thanks in advance for any help. :)
Stuart.

Commented out for the moment. */

fails */

  xml = glade_xml_new("famulus.glade", NULL, NULL);
  glade_xml_signal_autoconnect(xml);

  GtkWidget* widget = glade_xml_get_widget(xml, name);

  g_object_unref(G_OBJECT(xml));

  return(widget);
}

  gtk_init(&argc, &argv);

  GtkWidget* wndMain = getElement("wndMain");

  gtk_widget_show_all(wndMain);

  gtk_main();

  return(0);
}
