I already thought of blocking handlers during refresh, but it means
adding two instructions (_block and _unblock) for each set_value().
A simple and clear sequence of instructions:
_set_value()
_set_value()
..
will be transformed in a complex, long and cryptic sequence of
instructions:
Have you tried
g_signal_handler_block (gpointer instance, gulong handler_id);
and
g_signal_handler_unblock (gpointer instance, gulong handler_id);
Putting these before and after your set_value() should temporarily block
the handler.
You get the handler_id from g_signal_connect(...):
handle
I have a SpinButton with an associated Adjustment. I connected a handler
for "value-changed" signal, because I have to make something when the
user changes the value. I sometimes need to change the value in the
code, using set_value() method of SpinButton or Adjustment. In this
case, I don't wa
