Constructor Detail

def self.new : self #

Creates a new event controller that will handle key events.


def self.new(*, name : String? = nil, propagation_limit : Gtk::PropagationLimit? = nil, propagation_phase : Gtk::PropagationPhase? = nil, widget : Gtk::Widget? = nil) #

Class Method Detail

def self.g_type : UInt64 #

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


Instance Method Detail

def forward(widget : Gtk::Widget) : Bool #

Forwards the current event of this @controller to a @widget.

This function can only be used in handlers for the [signal@Gtk.EventControllerKey::key-pressed], [signal@Gtk.EventControllerKey::key-released] or Gtk::EventControllerKey::#modifiers signals.


def group : UInt32 #

Gets the key group of the current event of this @controller.

See Gdk::KeyEvent#layout.


def im_context : Gtk::IMContext? #

Gets the input method context of the key @controller.


def im_context=(im_context : Gtk::IMContext?) : Nil #

Sets the input method context of the key @controller.

def key_pressed_signal #

def key_released_signal #
