XPropertyEvent(3X11) XLIB FUNCTIONS XPropertyEvent(3X11)NAMEXPropertyEvent - 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.
