Introduction to Qt Widgets (Part 27) - Validating Input
As a user, there is nothing more annoying than a dialog saying "192.168.0.256 is not a valid IP address". Instead of allowing your user to type in invalid data, help them instead.
There are three tools in your toolbox for that, namely input masks, validators and completers.

About the host:
The video is presented by Jesper Pedersen, who started with Qt back when Qt was widgets only and the version was 1.44, which gives him 21 years of experience with Qt. Since 2000 he has taught almost 100 Qt classes, ranging from Qt Widgets to QML. Heck, Jesper even taught a few classes on QTopia Core — Trolltech's initial attempt at creating a phone stack. Today Jesper holds a fancy business title, but that doesn't prevent him from coding both in his job and in his spare time.
