XPropertyEvent - PropertyNotify
event structure
The structure for PropertyNotify events contains:
0
0>=40 .vs 0u
0<=39 .vs 0p
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.
