in reply to Display new widgets after MainLoop

(after MainLoop has been called)

Not after the MainLoop. This loop never exits (if you don't destroy the MainWindow, that is).

Instead, you bind events to code (subroutines), which does what you want (e.g. create widgets). Then if a event is triggered, the code bound to this event is executed.

populate a grid managed frame

You just create those widgets as children of the frame:

$Frame->$Widget(@args);

where $Widget is Button, Frame, Entry, Canvas, ... etc.

    It's been a while since TK for me..but i do remember that had to re-pack parent container under certain circumstances to get widgets to update.
    the hardest line to type correctly is: stty erase ^H
