Ip Address Validation

[wysota]

IMO fixup() should not display any pop-ups. It should convert an invalid entry to a valid one. If you want to display a popup, you can handle focusOut()/returnPressed()/whatever, call the validator from there manually and display a popup if the validator claims the entry to be invalid.

I agree, actually, I was thinking that earlier today.
What do you think about fixup() emitting a signal which can be handled elsewhere? Thanks for your help.

Bad idea. You never know when fixup() might be called and if it started emitting signals in arbitrary moments, it might not be what your users expect.

Ok, good. It did seem a little like bad practise to me.
Looks like I'll be learning about events now then
