response_type

The type of this event, in this case XCB_EXPOSE. This field is also present in the xcb_generic_event_t and can be used to tell events apart from each other.

sequence

The sequence number of the last request processed by the X11 server.

window

The exposed (damaged) window.

x

The X coordinate of the left-upper corner of the exposed rectangle, relative to the window's origin.

y

The Y coordinate of the left-upper corner of the exposed rectangle, relative to the window's origin.

width

The width of the exposed rectangle.

height

The height of the exposed rectangle.

count

The amount of Expose events following this one. Simple applications that do not want to optimize redisplay by distinguishing between subareas of its window can just ignore all Expose events with nonzero counts and perform full redisplays on events with zero counts.
