.TH XClientMessageEvent 3X11 "Release 5" "X Version 11" "XLIB FUNCTIONS"
|

.SH NAME
|
|
XClientMessageEvent \- ColormapNotify event structure
|
|
.SH STRUCTURES
|
|
The structure for
|
|
.ZN ClientMessage
|
|
events contains:
|
|
.LP
|
|
.Ds 0
|
|
.TA .5i 1i 3i
|
|
.ta .5i 1i 3i
|
|
typedef struct {
|
|
int type; /* ClientMessage */
|
|
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 message_type;
|
|
int format;
|
|
union {
|
|
char b[20];
|
|
short s[10];
|
|
long l[5];
|
|
} data;
|
|
} XClientMessageEvent;
|
|
.De
|
|
.LP
|
|
When you receive this event,
|
|
the structure members are set as follows.
|
|
.LP
|
|
The type member is set to the event type constant name that uniquely identifies
|
|
it.
|
|
For example, when the X server reports a
|
|
.ZN GraphicsExpose
|
|
event to a client application, it sends an
|
|
.ZN XGraphicsExposeEvent
|
|
structure with the type member set to
|
|
.ZN GraphicsExpose .
|
|
The display member is set to a pointer to the display the event was read on.
|
|
The send_event member is set to
|
|
.ZN True
|
|
if the event came from a
|
|
.ZN 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.
|
|
.LP
|
|
The message_type member is set to an atom that indicates how the data
|
|
should be interpreted by the receiving client.
|
|
The format member is set to 8, 16, or 32 and specifies whether the data
|
|
should be viewed as a list of bytes, shorts, or longs.
|
|
The data member is a union that contains the members b, s, and l.
|
|
The b, s, and l members represent data of 20 8-bit values,
|
|
10 16-bit values, and 5 32-bit values.
|
|
Particular message types might not make use of all these values.
|
|
The X server places no interpretation on the values in the window,
|
|
message_type, or data members.
