Glib::SignalProxy<int(double&)> Gtk::SpinButton::signal_input ( )
Slot Prototype:
int on_my_input(double& new_value)

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_valueReturn location for the new value.
Returns
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.

[C example ellipted]

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

The signal_value_changed() signal is emitted when the value represented by spinbutton changes. Also see the Gtk::SpinButton::signal_output() signal.

Glib::SignalProxy<void()> Gtk::SpinButton::signal_wrapped ( )
Slot Prototype:
void on_my_wrapped()

Flags: Run Last

The signal_wrapped() signal is emitted right after the spinbutton wraps from its maximum to minimum value or vice-versa.

void Gtk::SpinButton::spin ( SpinType  direction,

Increment or decrement a spin button’s value in a specified direction by a specified amount.

Parameters
directionA Gtk::SpinType indicating the direction to spin.
