Chapter 5. Range Widgets |
|
The update policy of a Range widget
defines at what points during user interaction it will change the
value field of its Gtk::Adjustment and
emit the value_changed signal. The update policies,
set with the set_update_policy() method, are:
Gtk::UPDATE_CONTINUOUS - This is the default. The
value_changed signal is emitted continuously, i.e. whenever the
slider is moved by even the tiniest amount.
Gtk::UPDATE_DISCONTINUOUS - The value_changed signal is
only emitted once the slider has stopped moving and the user has
released the mouse button.
Gtk::UPDATE_DELAYED - The value_changed signal is emitted
when the user releases the mouse button, or if the slider stops moving
for a short period of time.
