change keyboard accelerators

[Michal ROMAN <michal roman nov sk>]

Hi,

I havedefined keyboard accelerators :

accel_group = gtk_accel_group_new ();
for (i = 0; i < 10; i++)
{
  accel_key = ...   
  accel_mods = ...
  gtk_widget_add_accelerator (button, "clicked", accel_group, accel_key,
accel_mods, GTK_ACCEL_VISIBLE);
}
gtk_accel_group_attach (accel_group, GTK_OBJECT (window));

In some cases I need change toolbar of window:

toolbar_window =	// old window toolbar
toolbar = 		// new toolbar
parent = GTK_WIDGET (toolbar_window)->parent;
gtk_widget_ref (toolbar_window);
gtk_container_remove (GTK_CONTAINER (parent), toolbar_window);
gtk_container_add (GTK_CONTAINER (parent), toolbar);
gtk_widget_show_all (toolbar);

Now I need remove old accelerators from window and define new ones (the
code above) for the new toolbar. How can I remove all old accelerators
from window?

Thank's for your advises.
Michal.
