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.

Class Method Detail

def self.g_type : UInt64 #

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

def self.parse_string(string : String) : self | Nil #

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:

Instance Method Detail

def ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.


def activate(flags : Gtk::ShortcutActionFlags, widget : Gtk::Widget, args : _ | Nil) : 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 hash(hasher) #
Description copied from class Reference

See Object#hash(hasher)


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.


[View source]
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.
