Problems with Toggle-Buttons

[Martin Bammer <e9525103 stud4 tuwien ac at>]

Hi,

I want to write an app which has two toggle-buttons. Each toggle-button can 
switch off the other button and set a variable. The problem now is that when 
a callback from one toggle-button calls:

gtk_toggle_button_set_active(TOGGLE_BUTTON(lookup_widget(GTK_WIDGET(togglebutton), 
"other_toggle_button")), FALSE);

the callback function of the other toggle-button is also called, because the 
function gtk_toggle_button_set_active emits a "clicked" and "toggled" signal.

I am searching for a simple method to change the state of the toggle-button 
without emitting a signal.

Greetings, Martin
