class Gtk::SignalAction

Overview

A Gtk::ShortcutAction that emits a signal.

Signals that are used in this way are referred to as keybinding signals, and they are expected to be defined with the %G_SIGNAL_ACTION flag.

Defined in:

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

Constructor Detail

def self.new(signal_name : String) : self #

Creates an action that when activated, emits the given action signal on the provided widget.

It will also unpack the args into arguments passed to the signal.

def self.new #

Initialize a new SignalAction.


[View source]
def self.new(*, signal_name : String | Nil = nil) #

def signal_name=(value : String) : String #

[View source]
def signal_name=(value : Nil) : Nil #

Set #signal_name property to nil.


[View source]
def signal_name? : String | Nil #

Same as #signal_name, but can return nil.
