Non focused child window

• Christiaan Hofman Non focused child window Aug 09 2005, 12:26
  Hi list,
  
  I am trying to get a child window that can become key but leave the
  focus on the parent window. Basically, I want that the parent window is
  not grayed out and can be selected and dragged without the child window
  loosing its first responder. This is very much the behavior of a sheet
  or a drawer (though I don't want the child window to run modal for the
  parent window).  Simply adding a childWindow does not seem to be
  enough. Can anyone tell me what I could be overlooking?
  
  Thanks,
  Christiaan

  You'll need to subclass both the parent window and child window.
  Have the parent window include the child window in its responder
  chain just ahead of its nextResponder.  In the child subclass,
  override -isKeyWindow to return the state of its parent window, and
  override -canBecomeKeyWindow (and maybe -canBecomeMainWindow) to
  return FALSE.
