Re: Examples of ComboBox using an explicit model?
Thanks to those who send examples on or off list. With the guidance of those I was able to figure out how the different bits fit together and get a working code. James ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

The g_signal_connect() function does indeed only pass one pointer for the fourth argument "data". All signals have a "data" argument to receive the one pointer.

Passing data to a callback (again)
I think I'm missing something fundamental here. My understanding is that I can pass one pointer to a callback and that's it. And that works. When I look at the example provided for "How do I validate/limit/filter the input to a GtkEntry?" in the Gtk+ FAQ (version 2.18.9 in my case) I see that the callback header looks like this: void insert_text_handler (GtkEntry *entry, const gchar *text, gint length, gint *position, gpointer data) The g_signal connect line looks like this: g_signal_connect(G_OBJECT(entry), "insert_text", G_CALLBACK (insert_text_handler), NULL); So we're passing NULL data to the callback function, but somehow that function is receiving const gchar *text, gint length, gint *position, gpointer data. This obviously doesn't square with the idea that you can pass one single pointer to a callback.

Re: DLL Hell on Windows..
Thanks, but I forgot to add. I am using GTK3 for this. I downloaded the (gtk3)bundle. Also I've included the libatk that was shipped with it. But it didn't seem to work. -- Kind Regards, Robin Vossen Please avoid sending me Word, Excel or PowerPoint attachments.
