Hi Edward,
Replace by GtkObject* object by GtkWidget* widget in the routine
'on_window_destroy'. On the other hand, use -export-dynamic. Otherwise,
you will get warnings running the executable:
(prueba:4108): Gtk-WARNING **: Could not find signal handler
'on_togglebutton1_clicked'. Did you compile with -rdynamic?
In other words:
$ gcc -o gtkprog gtkprog.c -export-dynamic `pkg-config --libs --cflags
gtk+-3.0`
HTH,
Aitor.

------------------------------ The command to compile: $ gcc -o gtkprog
gtkprog.c `pkg-config --libs --cflags gtk+-3.0` Could anyone shed some
light on what I am doing wrong? Edward
