XPropertyEvent(3X11)X Version 11 (Release 6.6XPropertyEvent(3X11)
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
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.
