NAME
       destroy - Destroy one or more windows

SYNOPSIS
       destroy ?window window ...?
_________________________________________________________________

DESCRIPTION
       This  command  deletes the windows given by the window arguments, plus all of their descendants.  If a window "."  is deleted then all win-
       dows will be destroyed and the application will (normally) exit.  The windows are destroyed in order, and if an error occurs in	destroying
       a window the command aborts without destroying the remaining windows.  No error is returned if window does not exist.

EXAMPLE
       Destroy all checkbuttons that are direct children of the given widget:
	      proc killCheckbuttonChildren {parent} {
		 foreach w [winfo children $parent] {
		    if {[winfo class $w] eq "Checkbutton"} {
		       destroy $w
		    }
		 }
	      }
