PtNumericInteger issue

Hi all,

I have a doubt regarding PtNumericInteger Widget. I understood that PtNumericInteger accepts only integer values. But when I write a sample application for testing, I found that if I type any other characters also, it is visible in the PtNumericInteger widget and if I move on to the next widget in my sample window, the value automatically changes to zero if there are no digits typed.

But I need the PtNumericInteger to discard other characters like alphabets, special characters etc and only the digits which are typed should be visible. I have tried to implement it programmatically by registering a changedcallback. But if any other characters is typed into the PtNumericInteger widget, i found that the changedcallback is not getting called.

So could anyone please help me with any suggestions to solve this issue?
