XGraphicsExposeEvent, XNoExposeEvent \- GraphicsExpose and NoExpose event structures
|
|
.SH STRUCTURES
|
|
The structures for
|
|
.ZN GraphicsExpose
|
|
and
|
|
.ZN NoExpose
|
|
events contain:
|
|
.LP
|

int count; /\(** if nonzero, at least this many more */

|
.LP
|
|
When you receive these events,
|
|
their structure members are set as follows.
|
|
.LP
|
|
The type member is set to the event type constant name that uniquely identifies
|
|
it.
|
|
For example, when the X server reports a
|
|
.ZN GraphicsExpose
|
|
event to a client application, it sends an
|
|
.ZN XGraphicsExposeEvent
|
|
structure with the type member set to
|
|
.ZN GraphicsExpose .
|
|
The display member is set to a pointer to the display the event was read on.
|
|
The send_event member is set to
|
|
.ZN True
|
|
if the event came from a
|
|
.ZN SendEvent
|
|
protocol request.
|
|
The serial member is set from the serial number reported in the protocol
|
|
but expanded from the 16-bit least-significant bits to a full 32-bit value.
|
|
The window member is set to the window that is most useful to toolkit
|
|
dispatchers.
|
|
.LP
|
|
Both structures have these common members: drawable, major_code, and minor_code.
|
|
The drawable member is set to the drawable of the destination region on
|
|
which the graphics request was to be performed.
|
|
The major_code member is set to the graphics request initiated by the client
|
|
and can be either
|
|
.ZN X_CopyArea
|
|
or
|
|
.ZN X_CopyPlane .
|
|
If it is
|
|
.ZN X_CopyArea ,
|
|
a call to
|
|
.ZN XCopyArea
|
|
initiated the request.
|
|
If it is
|
|
.ZN X_CopyPlane ,
|
|
a call to
|
|
.ZN XCopyPlane
|
|
initiated the request.
|
|
These constants are defined in
|
|
.hN X11/Xproto.h .
|
|
The minor_code member,
|
|
like the major_code member,
|
|
indicates which graphics request was initiated by
|
|
the client.
|
|
However, the minor_code member is not defined by the core
|
|
X protocol and will be zero in these cases,
|
|
although it may be used by an extension.
|
|
.LP
|
|
The
|
|
.ZN XGraphicsExposeEvent
|
|
structure has these additional members: x, y, width, height, and count.
|
|
The x and y members are set to the coordinates relative to the drawable's origin
|
|
and indicate the upper-left corner of the rectangle.
|
|
The width and height members are set to the size (extent) of the rectangle.
|
|
The count member is set to the number of
|
|
.ZN GraphicsExpose
|
|
events to follow.
|
|
If count is zero, no more
|
|
.ZN GraphicsExpose
|
|
events follow for this window.
|
|
However, if count is nonzero, at least that number of
|
|
.ZN GraphicsExpose
|
|
events (and possibly more) are to follow for this window.
