Hi,
You're not using the right callback format for the "clicked" signal.
http://library.gnome.org/devel/gtk/stable/GtkToolButton.html#GtkToolButton-clicked
You're using for both handler 1 and handler 2:
void user_function (void)
while it should be:
void user_function (GtkToolButton *toolbutton, gpointer user_data)
When you use a signal, ALWAYS look at the prototype you need to use for
the callback.
This way, as you do the same thing in both callbacks, you can use a
single callback to process the signals emitted by both buttons:
void on_toolbutton_clicked (GtkToolButton *toolbutton,
gpointer user_data)
{
gtk_widget_hide (GTK_WIDGET (toolbutton));
}
Hope this resolves your problem...
Cheers,
Luis
