[R-gui] A GUI question

Thanks so much, James,

But one thing I'd better make it clearer.

I want to design an user interface, of course, base on GUI tools.
Ideally, it's a frame which contains top menu bar in the top-left area;
output window in the top-right area; and text message (task running
message, error message, or whatever other message) at the whole bottom
area.

From Tcl/Tk help/samples, it's possible to make it separately, I am

going to read those ActiveTcl doc, is there anyway to integrate those
different Tcl/Tk functions within one frame? I bet it may need some
other tools, such as ActiveTcl.

Thank you again, James!
