Perl/Tk saves your favourite tools
back: Atsar encap -1
next: Creating Tk-widgets
For each of the columns, we create a label to show the value related to
that column. Of course, you have to create a explanatory label with the name
of the field for the user too, but for the simplicity of the slide,
I left that one out.
In the above program, the order of the column(-labels) is kept in
@f, and used to refill the hash with actual measured values
on the moment the next line of output from atsar arrives.
The magic of Tk had caused a label to be tied to the hash-values: so with
us changing the values, the screen gets automatically updated!
Yes: this is all we need to create an interface as shown above... the
main window and one of its sub-windows are shown. Compare it to the
source to get the final touch.
