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.
