get_event_type() will return one of Gdk::Event::Type::EXPOSE, Gdk::Event::Type::DAMAGE.
Gdk::EventExpose::EventExpose | ( | ) |
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. |
const Gdk::Rectangle& Gdk::EventExpose::get_area | ( | ) | const |
Returns the bounding box of the region to be redrawn.
int Gdk::EventExpose::get_count | ( | ) | const |
Returns the number of contiguous Gdk::Event::Type::EXPOSE events following this one.
The only use for this is "exposure compression", i.e. handling all contiguous Gdk::Event::Type::EXPOSE events in one go, though GDK performs some exposure compression so this is not normally needed.
::Cairo::RefPtr<const ::Cairo::Region> Gdk::EventExpose::get_region | ( | ) | const |
Returns the region to be redrawn.

GdkEventExpose* Gdk::EventExpose::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.
