SpinButton.connectInput

Connect to Input signal.

The ::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.entry.Entry.getText to retrieve the text of the entry and set new_value to the new value.

The default conversion uses glib.global.strtod.
