XClientMessageEvent.3X11.z(3X11)



     X Version 11 (Release 5)                XClientMessageEvent(3X11)



     NAME
          XClientMessageEvent - ColormapNotify event structure

     STRUCTURES
          The structure for ClientMessage 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 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 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.
