NAME
  XPropertyEvent - PropertyNotify event	structure

STRUCTURES
  The structure	for _P_r_o_p_e_r_t_y_N_o_t_i_f_y events contains:

  typedef struct {
	  int type;	  /* PropertyNotify */
	  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 */
	  Window window;
	  Atom atom;
	  Time time;
	  int state;	  /* PropertyNewValue or PropertyDelete	*/
  } XPropertyEvent;

  When you receive this	event, the 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.

  The window member is set to the window whose associated property was
  changed.  The	atom member is set to the property's atom and indicates	which
  property was changed or desired.  The	time member is set to the server time
  when the property was	changed.  The state member is set to indicate whether
  the property was changed to a	new value or deleted and can be	_P_r_o_p_e_r_-
  _t_y_N_e_w_V_a_l_u_e or	_P_r_o_p_e_r_t_y_D_e_l_e_t_e.	 The state member is set to _P_r_o_p_e_r_t_y_N_e_w_V_a_l_u_e
  when a property of the window	is changed using _X_C_h_a_n_g_e_P_r_o_p_e_r_t_y or _X_R_o_t_a_-
  _t_e_W_i_n_d_o_w_P_r_o_p_e_r_t_i_e_s (even when	adding zero-length data	using _X_C_h_a_n_g_e_P_r_o_-
  _p_e_r_t_y) and when replacing all	or part	of a property with identical data
  using	_X_C_h_a_n_g_e_P_r_o_p_e_r_t_y	or _X_R_o_t_a_t_e_W_i_n_d_o_w_P_r_o_p_e_r_t_i_e_s.  The state member is set
  to _P_r_o_p_e_r_t_y_D_e_l_e_t_e when a property of the window is deleted using
  _X_D_e_l_e_t_e_P_r_o_p_e_r_t_y or, if the delete argument is	_T_r_u_e, _X_G_e_t_W_i_n_d_o_w_P_r_o_p_e_r_t_y.
