/*
   "Everything you ever wanted to know about the default buttons" or "Why do we
   have to do all this?"

   In MSW the default button should be activated when the user presses Enter
   and the current control doesn't process Enter itself somehow. This is
   handled by ::DefWindowProc() (or maybe ::DefDialogProc()) using DM_SETDEFID
   Another aspect of "defaultness" is that the default button has different
   appearance: this is due to BS_DEFPUSHBUTTON style which is completely
   separate from DM_SETDEFID stuff (!). Also note that BS_DEFPUSHBUTTON should
   be unset if our parent window is not active so it should be unset whenever
   we lose activation and set back when we regain it.

   Final complication is that when a button is active, it should be the default
   one, i.e. pressing Enter on a button always activates it and not another
   one.

   We handle this by maintaining a permanent and a temporary default items in
   wxControlContainer (both may be NULL). When a button becomes the current
   control (i.e. gets focus) it sets itself as the temporary default which
   ensures that it has the right appearance and that Enter will be redirected
   to it. When the button loses focus, it unsets the temporary default and so
   the default item will be the permanent default -- that is the default button
   if any had been set or none otherwise, which is just what we want.

   NB: all this is quite complicated by now and the worst is that normally
       it shouldn't be necessary at all as for the normal Windows programs
       DefWindowProc() and IsDialogMessage() take care of all this
       automatically -- however in wxWidgets programs this doesn't work for
       nested hierarchies (i.e. a notebook inside a notebook) for unknown
       reason and so we have to reproduce all this code ourselves. It would be
       very nice if we could avoid doing it.
