[Glade-users] Closing a dialog window

[chris-morrison rassalom-technology co uk (Chris Morrison)]

Hi all,

This is probably more of a GNOME programming question than a Glade one
but here goes.

I am writing a small program in Glade that displays a dialog window on
the screen with a Close button. Clicking the close button closes the
dialog and ends the program.

I have placed the following code in the signal handler for the Close
button's click event.

void on_closebutton_clicked(GtkButton *button, gpointer window_ptr)
{
  GtkDialog *window = GTK_DIALOG(window_ptr);
  gtk_widget_destroy(GTK_WIDGET(window));
}

However, when I click on the Close button nothing happens and the
following message is displayed in the terminal window.

(my-program:5534): Gtk-CRITICAL **: file gtkwidget.c: line 1911
(gtk_widget_destroy): assertion `GTK_IS_WIDGET (widget)' failed

I am a newbie to Linux programming as you can tell, I have just migrated
from Micro$oft Windoze.

Any pointers (no pun intended) would be appreciated.


Regards,


Chris
