How to dynamically change GTK window title?

Hello friends,

I am a newbie to C programming and GTK.

I want to change the tile of the the GTK top level window from the click of a button.

A form with three buttons each sets different title to the parent window, how to do this.

I had written a bad code with these errors:

Code:

---

GLib-GObject-WARNING **: invalid uninstantiatable type `(null)' in cast to `GtkWindow'

Gtk-CRITICAL **: IA__gtk_window_set_title: assertion `GTK_IS_WINDOW (window)' failed

---

have you tried the GTK Reference?

Yeah,

I had referenced the link you provided. But, it doesn't provide much detail.
Please help.

it looks to me like you are passing a null pointer to gtk_window_set_title(). check to be sure that you have a valid pointer to the window when trying to do this.

Is there anyone who can give me solution with proper example. Coz, I couldn't get it to work till now.

Thanks Elkvis,

Problem solved. there was really a NULL pointer referencing the gtk_window_set_title().
