Tk vs Tkx for -validatecommandby shortyfw06 (Beadle)
|on Sep 19, 2012 at 14:00 UTC||Need Help??|
shortyfw06 has asked for the
wisdom of the Perl Monks concerning the following question:
For an entry widget in Tk, I used the following validate command to only allow negative and positive integers. This would give an immediate error if a letter or other character was entered. In Tkx, I do not get an error when the entry is invalid. Is there a different way to do this in Tkx?
