struct Gtk::SpinButton::InputSignal

Overview

Emitted to convert the users input into a double value.

The signal handler is expected to use Gtk::Editable#text to retrieve the text of the spinbutton and set @new_value to the new value.

The default conversion uses g_strtod().

Defined in:

lib/gi-crystal/src/auto/gtk-4.0/spin_button.cr
