get_event_type() will return Gdk::Event::Type::KEY_PRESS or Gdk::Event::Type::KEY_RELEASE.
Gdk::EventKey::EventKey | ( | ) |
Creates an invalid event object.
Calling any member functions is undefined behavior.
|
explicit |
Wraps a C event instance.
This constructor either acquires ownership of gobject, or copies it.
gobject | Event to wrap. |
make_a_copy | If false , the ownership of gobject is acquired, otherwise, a copy is made. |
guint8 Gdk::EventKey::get_group | ( | ) | const |
Returns the keyboard group.
guint16 Gdk::EventKey::get_hardware_keycode | ( | ) | const |
Returns the raw code of the key that was pressed or released.
bool Gdk::EventKey::get_is_modifier | ( | ) | const |
Returns true
if the hardware keycode is mapped to a modifier key.
guint Gdk::EventKey::get_keyval | ( | ) | const |
Returns the key that was pressed or released.
See the <gdk/gdkkeysyms.h> header file for a complete list of GDK key codes.
int Gdk::EventKey::get_scancode | ( | ) | const |
Gets the keyboard low-level scancode of a key event.
This is usually hardware_keycode. On Windows this is the high word of WM_KEY{DOWN,UP} lParam which contains the scancode and some extended flags.
ModifierType Gdk::EventKey::get_state | ( | ) | const |
Returns a bit mask representing the state of the modifier keys (e.g.
Control, Shift and Alt) and the pointer buttons.
guint32 Gdk::EventKey::get_time | ( | ) | const |
Returns the timestamp of the event in milliseconds.

GdkEventKey* Gdk::EventKey::gobj_copy | ( | ) | const |
Provides access to the underlying C instance.
The caller is responsible for freeing it with gdk_event_free(). Use when directly setting fields in structs.

A Glib::wrap() method for this object.
object | The C instance. |
take_copy | False if the result should take ownership of the C instance. True if it should take a new copy. |
|
related |
Wraps a C event instance without making unnecessary copy when the ownership can not be acquired.
The event pointer must not be deleted until last usage of the returned instance. Note, that this requirement applies to the pointer itself, in addition to the object it is pointing to.
