Precedence of Callback Functions

Events trigger callback functions in the following order:

• For control operation events:
  
  
  1. Control callback
  2. Main callback
  3. Panel callback (keypress and mouse events only)
  4. Main callback
• For panel events:
  
  
  1. Panel callback
  2. Main callback
• For menu commit events:
  
  
  1. Menu item callback
  2. Main callback
• Timer control event: Control callback
• Main callback event: Main callback

Note  The commit event is placed in the GetUserEvent queue after being sent to all callbacks.
