gtk_event_controller_key_new ()

GtkEventController *
gtk_event_controller_key_new (void);

Creates a new event controller that will handle key events.

gtk_event_controller_key_set_im_context ()

void
gtk_event_controller_key_set_im_context
                               (GtkEventControllerKey *controller,
                                GtkIMContext *im_context);

Sets the input method context of the key controller .

gtk_event_controller_key_get_im_context ()

GtkIMContext *
gtk_event_controller_key_get_im_context
                               (GtkEventControllerKey *controller);

Gets the input method context of the key controller .

gtk_event_controller_key_forward ()

gboolean
gtk_event_controller_key_forward (GtkEventControllerKey *controller,
                                  GtkWidget *widget);

Forwards the current event of this controller to a widget .

This function can only be used in handlers for the “key-pressed”, “key-released” or “modifiers” signals.

gtk_event_controller_key_get_group ()

guint
gtk_event_controller_key_get_group (GtkEventControllerKey *controller);

Gets the key group of the current event of this controller . See gdk_key_event_get_group().

GtkEventControllerKey

typedef struct _GtkEventControllerKey GtkEventControllerKey;

The “im-update” signal

void
user_function (GtkEventControllerKey *controller,
               gpointer               user_data)

This signal is emitted whenever the input method context filters away a keypress and prevents the controller receiving it. See gtk_event_controller_key_set_im_context() and gtk_im_context_filter_keypress().

The “key-pressed” signal

gboolean
user_function (GtkEventControllerKey *controller,
               guint                  keyval,
               guint                  keycode,
               GdkModifierType        state,
               gpointer               user_data)

This signal is emitted whenever a key is pressed.

The “key-released” signal

void
user_function (GtkEventControllerKey *controller,
               guint                  keyval,
               guint                  keycode,
               GdkModifierType        state,
               gpointer               user_data)

This signal is emitted whenever a key is released.

Flags: Run Last

The “modifiers” signal

gboolean
user_function (GtkEventControllerKey *controller,
               GdkModifierType        keyval,
               gpointer               user_data)

This signal is emitted whenever the state of modifier keys and pointer buttons change.
