Hi,
you don't necessarily need the handler id. In C (I don't use
python) you could write the following:
void my_set_value(GtkSpinButton *spin_button, gdouble value)
{
g_signal_handlers_block_matched(spin_button,
G_SIGNAL_MATCH_FUNC,
0, 0, NULL,
callback_to_skip,
NULL);
/* This will not trigger callback_to_skip */
gtk_spin_button_set_value(spin_button, value)
g_signal_handlers_unblock_matched(spin_button,
G_SIGNAL_MATCH_FUNC,
0, 0, NULL,
callback_to_skip,
NULL);
}
Not tested, but should give you the idea.
Ciao.
