public class XClientMessageEvent

implements NativeResource
```
Client message event.
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 twenty 8-bit values, ten 16-bit values, and five 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.

- serial – # of last request processed by server
- send_event – true if this came from an X11.XSendEvent(long, long, boolean, long, org.lwjgl.system.linux.XEvent) request
