Hi all!
=0D
If anyone is very familiar with Tk I would be very grateful for a few=
 pointers.
=0D
Basically I'm looking to feedback my program's output to the user in a GUI=
 (Tk Label) rather than printing to the console (which it currently does).=
 This information would simply be a string to let the user know what's=
 going on and maybe even what percentage of the work has been done. I don't=
 want a command/bound event to drive this - I simply want to send a message=
 to a method which will update the Tk Label dynamically.
=0D
I envision the calling the class like this:
=0D
    @output =3D GraphicalOutput.new
    @output.message("Now moving files....")
=0D
to replace the current:
    p "Now moving files..."
=0D
Is this possible with Tk? I've been looking for days now and haven't found=
 much. I know how to use the TkLabel.configure('text'=3D>..) etc. to update=
 the text, however just calling this when the mainloop is running does not=
 seem to dynamically update the label. I've even got the stopwatch example=
 going from the O'Reilly cookbook.
=0D
Am I using the wrong approach and/or mentality for this problem?!=0D
=0D
Again I will be very grateful for anyone's help! Thanks in advance!!!
