NAME
  XGraphicsExposeEvent,	XNoExposeEvent - GraphicsExpose	and NoExpose event
  structures

STRUCTURES
  The structures for _G_r_a_p_h_i_c_s_E_x_p_o_s_e and	_N_o_E_x_p_o_s_e events	contain:

  typedef struct {
	  int type;	  /* GraphicsExpose */
	  unsigned long	serial;	  /* # of last request processed by server */
	  Bool send_event;	  /* true if this came from a SendEvent	request	*/
	  Display *display;	  /* Display the event was read	from */
	  Drawable drawable;
	  int x, y;
	  int width, height;
	  int count;	  /* if	nonzero, at least this many more */
	  int major_code; /* core is CopyArea or CopyPlane */
	  int minor_code; /* not defined in the	core */
  } XGraphicsExposeEvent;

  typedef struct {
	  int type;	  /* NoExpose */
	  unsigned long	serial;	  /* # of last request processed by server */
	  Bool send_event;	  /* true if this came from a SendEvent	request	*/
	  Display *display;	  /* Display the event was read	from */
	  Drawable drawable;
	  int major_code; /* core is CopyArea or CopyPlane */
	  int minor_code; /* not defined in the	core */
  } XNoExposeEvent;

  When you receive these events, their structure members are set as follows.

  The type member is set to the	event type constant name that uniquely iden-
  tifies it.  For example, when	the X server reports a _G_r_a_p_h_i_c_s_E_x_p_o_s_e event
  to a client application, it sends an _X_G_r_a_p_h_i_c_s_E_x_p_o_s_e_E_v_e_n_t structure with
  the type member set to _G_r_a_p_h_i_c_s_E_x_p_o_s_e.  The display member is	set to a
  pointer to the display the event was read on.	 The send_event	member is set
  to _T_r_u_e if the event came from a _S_e_n_d_E_v_e_n_t 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.

  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 _X__C_o_p_y_A_r_e_a or _X__C_o_p_y_P_l_a_n_e.  If	it is _X__C_o_p_y_A_r_e_a, a call to _X_C_o_p_y_A_r_e_a
  initiated the	request.  If it	is _X__C_o_p_y_P_l_a_n_e,	a call to _X_C_o_p_y_P_l_a_n_e ini-
  tiated the request.  These constants are defined in <_X_1_1/_X_p_r_o_t_o._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.

  The _X_G_r_a_p_h_i_c_s_E_x_p_o_s_e_E_v_e_n_t 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 _G_r_a_p_h_i_c_s_E_x_p_o_s_e
  events to follow.  If	count is zero, no more _G_r_a_p_h_i_c_s_E_x_p_o_s_e events follow
  for this window.  However, if	count is nonzero, at least that	number of
  _G_r_a_p_h_i_c_s_E_x_p_o_s_e events	(and possibly more) are	to follow for this window.
