// System predefined widget message types. Message types are constants  
// that indicate which widget sent the message and by which widget      
// function (sub-message). Make sure your own message types don't clash  
// whith the ones defined in this file. ROOT reserves all message ids   
// between 0 - 1000. User defined messages should be in the range       
// 1001 - 10000. Sub-messages must always be in the range 1-255.        
// To use MK_MSG() just cast your message id's to an EWidgetMessageType.
