Adding a command to a Pmw.counter widget

[Mark Light]

Hi,
I have a Pmw.Counter widget and I would like to add a command that
is called on pressing either the up or down arrows (the command will be
the same for both). I have managed to do this for the entryfield with
"entryfield_command = ", but can't get the same to work for the arrows,
could someone help me out with how to do this.

Many thanks,

Mark.

Looking at the source for the PmwCounter it doesn't look like it exposes
the buttons callbacks.

I think the best way to do this would be to provide a validator method
to the Counter's entryfield. The validator gets called whenever the
entryfields value changes.

Example validator methods are included in the Pmw documentation.
