Rarely used event.
Generated when a stylus has moved in or out of contact with the tablet, or perhaps that the user's finger has moved in or out of contact with a touch screen.
This event type will be used pretty rarely. It only is important for XInput aware programs that are drawing their own cursor.
get_event_type() will return one of Gdk::Event::Type::PROXIMITY_IN, Gdk::Event::Type::PROXIMITY_OUT.
Gdk::EventProximity::EventProximity | ( | ) |
Creates an invalid event object.
Calling any member functions other than operator bool() is undefined behavior. An invalid event object can be used in a function call, if the underlying C function expects a NULL GdkEventProximity pointer.
|
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. |
Glib::RefPtr<Gdk::Device> Gdk::EventProximity::get_device | ( | ) |
Returns the device where the event originated from.
Glib::RefPtr<const Gdk::Device> Gdk::EventProximity::get_device | ( | ) | const |
guint32 Gdk::EventProximity::get_time | ( | ) | const |
Returns the timestamp of the event in milliseconds.

GdkEventProximity* Gdk::EventProximity::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.
