I can move Label around now, but not very smoothly. Finally, I realize
that I won't be able to put a childwindows generated by plot() into a
widget. If it is possible, does it mean embedding GraphApp in Tk?

BTW, after modifying windlgs a little bit, I make it a childwindow. Hope
that I can make more progress on that. And I will appreciate it, if anyone
can tell me some related and more detailed references about those
extensions to GraphApp in R source.
