Hello,
I search (and try hard ) to run this pango/gtk+ "application". Its only
should put a string to a pango-layout.
It didn't work. (Nothing will happen on the graphicwindow...)
Its a main.c and the eventhandler for expose from my interface.c
If needed, I will post the glade3 XML too.
Big thanks for any helps.
Best regard
CODE: main.c
gtk_set_locale ();
gtk_init (&argc, &argv);
gxml = glade_xml_new (GLADE_FILE, NULL, NULL);
glade_xml_signal_autoconnect (gxml);
window = glade_xml_get_widget (gxml, "window");
fixed = glade_xml_get_widget (gxml, "fixed1");
connect = glade_xml_get_widget (gxml, "connect");
console = glade_xml_get_widget (gxml, "console");
da = glade_xml_get_widget ( gxml, "drawingarea1");
....

g_signal_connect (window, "expose-event",
G_CALLBACK (on_expose_event), da);
gtk_widget_show (window);
gtk_main ();
