XClientMessageEvent(3X11)	     X11R5	     XClientMessageEvent(3X11)

NAME
       XClientMessageEvent - ColormapNotify event structure

STRUCTURES
       The structure for events contains:

       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;

       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 event to a
       client application, it sends an structure with the type member set to
       The display member is set to a pointer to the display the event was
       read on.	 The send_event member is set to if the event came from a pro‐
       tocol 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 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.	Par‐
       ticular message types might not make use of all these values.  The X
       server places no interpretation on the values in the window, mes‐
       sage_type, or data members.
