Am I being obtuse or couldn't you just use the provided !D.WINDOW sysvar in the
focus event callback simply as:

widget_control,self.mywin,get_value=win
wset,win

I do this all the time at the same time as resetting colors.  All plot commands
then go to the relevant chosen window.  One issue is with using tracking events
for the callback, so that by the time the user has returned to the command line,
another window has been unintentionally entered.  You can also try expose and/or
keyboard focus events.

Or is this an object graphics thing?  I'm embarrassed to say that I have yet to
invoke a single O.G. command.  Too many case changes and underlines make my code
ugly (IDL_ThisDISPlays_a_VIEWofaModel_withinAConTainerofWindowsgrdotcom).
