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.
