XPropertyEvent - PropertyNotify event structure


STRUCTURES

       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 applica-
       tion, 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 prop-
       erty'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 prop-
       erty 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 Prop-
       ertyDelete when a property of the window is deleted using
       XDeleteProperty or, if the delete argument is True,
       XGetWindowProperty.
