int on_my_input(double& new_value)
Flags: Run Last
The signal_input() signal can be used to influence the conversion of the users input into a double value. The signal handler is expected to use Gtk::Editable::get_text() to retrieve the text of the spinbutton and set new_value to the new value.
The default conversion uses Glib::strtod().
new_value | Return location for the new value. |
true
for a successful conversion, false
if the input was not handled, and GTK_INPUT_ERROR if the conversion failed. Glib::SignalProxy<bool()> Gtk::SpinButton::signal_output | ( | ) |

The signal_output() signal can be used to change to formatting of the value that is displayed in the spin buttons entry.

true
if the value has been displayed. Glib::SignalProxy<void()> Gtk::SpinButton::signal_value_changed | ( | ) |
void on_my_value_changed()
