 Name

    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 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 sendevent 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.
