Struct gtk4::EventControllerKey[][src]

pub struct EventControllerKey(_);
Expand description

EventControllerKey is an event controller that provides access to key events.

Implements

EventControllerExt, glib::ObjectExt

Implementations

Creates a new event controller that will handle key events.

Returns

a new EventControllerKey

Creates a new builder-pattern struct instance to construct EventControllerKey objects.

This method returns an instance of EventControllerKeyBuilder which can be used to create EventControllerKey objects.

Forwards the current event of this self to a widget.

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

widget

a Widget

Returns

whether the widget handled the event

Gets the key group of the current event of this self.

See Gdk::KeyEvent::get_layout()``.

Returns

the key group

Gets the input method context of the key self.

Returns

the IMContext

Sets the input method context of the key self.

im_context

a IMContext

Emitted whenever the input method context filters away a keypress and prevents the controller receiving it.

See set_im_context() and IMContextExtManual::filter_keypress().

Emitted whenever the state of modifier keys and pointer buttons change.

keyval

the released key.

Emitted whenever a key is pressed.

keyval

the pressed key.

keycode

the raw code of the pressed key.

state

the bitmask, representing the state of modifier keys and pointer buttons. See gdk::ModifierType.

Returns

true if the key press was handled, false otherwise.

Emitted whenever a key is released.

keyval

the released key.

keycode

the raw code of the released key.

state

the bitmask, representing the state of modifier keys and pointer buttons. See gdk::ModifierType.
