Gdk::EventFocus::EventFocus | ( | ) |
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. |
bool Gdk::EventFocus::get_focus | ( | ) | const |
true
if the window gained focus, false
if lost

GdkEventFocus* Gdk::EventFocus::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.

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. |
|

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.
