destroy(n) Tk Built-In Commands destroy(n) 







destroy - Destroy one or more windows








destroy ?window window ...?










This command deletes the windows given by the window
    arguments, plus all of their descendants. If a window
    “.” is deleted then all windows 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.








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
      }
   }
}
