The "focus-in" signal

lambda (controller)    :run-last      

controller

The gtk:event-controller-key object on which the signal is emitted.

The "focus-out" signal

lambda (controller)    :run-last      

controller

The gtk:event-controller-key object on which the signal is emitted.

The "im-update" signal

lambda (controller)    :run-last      

controller

The gtk:event-controller-key object on which the signal is emitted.

The "key-pressed" signal

lambda (controller keyval keycode state)    :run-last      

The signal is emitted whenever a key is pressed.

controller

The gtk:event-controller-key object on which received the signal.

keyval

An unsigned integer with the pressed key.

keycode

An unsigned integer with the raw code of the pressed key.

state

The gdk:modifier-type bitmask representing the state of modifier keys and pointer buttons.

Returns

True if the key press was handled, false otherwise.

The "key-released" signal

lambda (controller keyval keycode state)    :run-last      

The signal is emitted whenever a key is released.

controller

The gtk:event-controller-key object on which received the signal.

keyval

An unsigned integer with the released key.

keycode

An unsigned integer with the raw code of the released key.

state

The gdk:modifier-type bitmask representing the state of modifier keys and pointer buttons.

The "modifiers" signal

lambda (controller state)    :run-last      

controller

The gtk:event-controller-key object on which received the signal.

state

The gdk:modifier-type bitmask, representing the state of modifier keys and pointer buttons.
