[A view of the application window]

• To highlight the label
  
  The button which displays "highlight by mouse" has two event procedures with WSEV_MOUSE_IN trigger and WSEV_MOUSE_OUT trigger.
  
  The WSEV_MOUSE_IN procedure stores the original back-color to WSNuserString and stores the highlight color to WSNbackColor.
  
  The WSEV_MOUSE_OUT procedure gets the original back-color from WSNuserString and stores it to WSNbackColor.
  
  
• To highlight the label (2)
  
  The button which displays "highlight by mouse(2)" has an event procedures with WSEV_INITIALIZE trigger which setups sub-procedures which trigger is WSN_MOUSE_IN and WSN_MOUSE_OUT.
  
  The initialize procedure like this simplifies because it not require that the instance has many procedures for one-function.
  
  
• To group the labels by an event procedure
  
  The button which displays "Click!" has a event procedures which trigger is WSEV_MOUSE_PRESS. This procedure make a group of the labels which has it by storing selected label to the parent instance : form or window. Then the labels highlights cooperated.
