Re: Examples of ComboBox using an explicit model?

Unfortunately unlike normal comboboxes where there is the convenience type of GtkComboBoxText this is not available for cell renderers. I have hunted for examples of a working combobox that uses an explicit tree model without any success. Does anybody on this list have such an example (or even better, of a CellRendererCombo) that they would be willing to share. You can have a look at the cell renderer I implemented for Libgda, cf http://git.gnome.org/browse/libgda/tree/libgda-ui/data-entries/gdaui-data-cell-renderer-combo.hand http://git.gnome.org/browse/libgda/tree/libgda-ui/data-entries/gdaui-data-cell-renderer-combo.c . This cell renderer displays a text, along with a down pointing triangle which, when clicked, displays a combo box.

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.

I hope somebody can give me the right version. Or maybe a way to determine the right version. Download the official bundle version (http://ftp.gnome.org/pub/gnome/binaries/win32/gtk+/2.24/gtk+-bundle_2.24.10-20120208_win32.zip), that contains all the DLLs GTK is made of and all the external dependencies. -- Bye, Gabry ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
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.

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. In the case of the insert-data signal it has a specific callback that provides additional data. Other callbacks will have different function arguments that will provide different data. In the end, the data pointer is the only pointer you can pass from outside any callback. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

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
