Re: [platform-swt-dev] GTK in CVS

Thanks Hovoc - the example from the documentation indicates that passing
NULL will add a log handler for all warning messages.  The code has been
corrected in CVS.  What values other than "gtk" and "gdk" are valid?

Here is some sample code that works for me:

     #include <gtk/gtk.h>
     #include <stdio.h>

     void
     log_func (const gchar    *log_domain,
               GLogLevelFlags  log_level,
               const gchar    *message,
               gpointer        user_data)
     {
       printf("HA-HA-HA\n");
     }


     int
     main (int argc, char **argv)
     {
       gtk_init (&argc, &argv);

       /* Use G_LOG_LEVEL_MASK to get all log levels, instead of just
        * CRITICAL/WARNING. 
        */
       g_log_set_handler ("Gtk",
                          G_LOG_LEVEL_CRITICAL | G_LOG_LEVEL_WARNING |
                          G_LOG_FLAG_FATAL | G_LOG_FLAG_RECURSION,
                          log_func, NULL);

       gtk_widget_show (NULL);

       return 0;
     }

I apologize for this API, it's sort of strange IMO. It's documented
here:

  http://developer.gnome.org/doc/API/2.0/glib/glib-message-logging.html

You may want to set a handler for the "Gdk" domain as well as "Gtk".

>         int handle = OS.gtk_window_new (OS.GTK_WINDOW_TOPLEVEL);

BTW, I've noticed some code that appears to stuff pointers into the
Java "int" type - isn't this going to blow up on 64-bit platforms?
Or am I misunderstanding the code?
