XPropertyEvent(3X11)

NAME

  XPropertyEvent - PropertyNotify event structure


DESCRIPTION

  The structure for PropertyNotify 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
  identifies it. For example, when the X server reports a GraphicsExpose
  event to a client application, it sends an XGraphicsExposeEvent structure
  with the type member set to GraphicsExpose. The display member is set to a
  pointer to the display the event was read on. The send_event member is set
  to True if the event came from a 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.

  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
  PropertyNewValue or PropertyDelete. The state member is set to
  PropertyNewValue when a property of the window is changed using
  XChangeProperty or XRotateWindowProperties (even when adding zero-length
  data using XChangeProperty) and when replacing all or part of a property
  with identical data using XChangeProperty or XRotateWindowProperties. The
  state member is set to PropertyDelete when a property of the window is
  deleted using XDeleteProperty or, if the delete argument is True,
  XGetWindowProperty.
