class Gio::SimpleAction

Overview

A #GSimpleAction is the obvious simple implementation of the #GAction interface. This is the easiest way to create an action for purposes of adding it to a #GSimpleActionGroup.

See also #Gtk::Action.

Constructor Detail

def self.new(name : String, parameter_type : GLib::VariantType?) : self #

Creates a new action.

The created action is stateless. See g_simple_action_new_stateful() to create an action that has state.


def self.new #

Initialize a new SimpleAction.


def self.new(*, enabled : Bool? = nil, name : String? = nil, parameter_type : GLib::VariantType? = nil, state : GLib::Variant? = nil, state_type : GLib::VariantType? = nil) #

def self.new_stateful(name : String, parameter_type : GLib::VariantType?, state : _) : self #

Creates a new stateful action.

All future state values must have the same #GVariantType as the initial @state.

If the @state #GVariant is floating, it is consumed.


Class Method Detail

def self.g_type : UInt64 #

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


Instance Method Detail

def activate_signal #

def change_state_signal #

def enabled=(enabled : Bool) : Nil #

Sets the action as enabled or not.

An action must be enabled in order to be activated or in order to have its state changed from outside callers.

This should only be called by the implementor of the action. Users of the action should not attempt to modify its enabled flag.


def enabled? : Bool #

def name : String #

def name=(value : String) : String #

def parameter_type : GLib::VariantType? #

def parameter_type=(value : GLib::VariantType?) : GLib::VariantType? #

def state : GLib::Variant? #

def state=(value : GLib::Variant?) : GLib::Variant? #

def state=(value : _) : Nil #

Sets the state of the action.

This directly updates the 'state' property to the given value.

This should only be called by the implementor of the action. Users of the action should not attempt to directly modify the 'state' property. Instead, they should call g_action_change_state() to request the change.

If the @value GVariant is floating, it is consumed.


def state_hint=(state_hint : _?) : Nil #

Sets the state hint for the action.

See g_action_get_state_hint() for more information about action state hints.


def state_type : GLib::VariantType? #
