class Gtk::ShortcutAction

Overview

Gtk::ShortcutAction encodes an action that can be triggered by a keyboard shortcut.

Gtk::ShortcutActions contain functions that allow easy presentation to end users as well as being printed for debugging.

All Gtk::ShortcutActions are immutable, you can only specify their properties during construction. If you want to change a action, you have to replace it with a new one. If you need to pass arguments to an action, these are specified by the higher-level Gtk::Shortcut object.

To activate a Gtk::ShortcutAction manually, Gtk::ShortcutAction#activate can be called.

GTK provides various actions:

Constructor Detail

def self.new #

Initialize a new ShortcutAction.


def self.parse_string(string : String) : self? #

Tries to parse the given string into an action.

On success, the parsed action is returned. When parsing failed, nil is returned.

The accepted strings are:


Class Method Detail

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.


Instance Method Detail

def activate(flags : Gtk::ShortcutActionFlags, widget : Gtk::Widget, args : _?) : Bool #

Activates the action on the @widget with the given @args.

Note that some actions ignore the passed in @flags, @widget or @args.

Activation of an action can fail for various reasons. If the action is not supported by the @widget, if the @args don't match the action or if the activation otherwise had no effect, false will be returned.


def print(string : GLib::String) : Nil #

Prints the given action into a string for the developer.

This is meant for debugging and logging.

The form of the representation may change at any time and is not guaranteed to stay identical.


def to_string : String #

Prints the given action into a human-readable string.

This is a small wrapper around Gtk::ShortcutAction#print to help when debugging.
