limit textedit input to just digits using regexp
Aug 12 2011 | 8:06 pm
I'm using code posted by Alex Harker (in turn built on work of Luke Hall) found elsewhere in the forum, to limit the number of characters entered in a textedit to a specific maximum number (5). I would also like to limit the input to *just* digits 0-9, no other characters. I tried to modify the regexp expression with info I found online, but I'm failing miserably.
Can anyone help?

I'm then filtering any spaces (32's) from this list via an [atoi]/[itoa] pair and a [zl filter 32]. When you get a non-matching input (e.g. the string "a") I'm clearing the textedit object.
