Hi,

Is there a way to avoid Paste to a Text widget ?

I've developed a widget to edit/localize numbers and i would like to avoid
paste number because they could be too long (problem with NumberFormat
limited to 16 digit) or of bad format.

I am using the VerifyListener to check the keyword input.

Thanks

Jmi

The verify listener is also invoked when text is pasted into the Text widget
so why not just verify that the pasted text matches the required format
rather than disabling paste?

You're rigth, i've tried with regex and (\\d+)([.]?)(\\d*) and it's OK for
a part of the solution, i think it's the good way...
