Introduction to Qt Widgets (Part 20) - Common Widgets

In this and the next three episodes, we will look at the most common widgets in Qt, their API, how you are supposed to work with them, and most noticeable some of the hidden gems.

We start out by looking at QLabel, QLineEdit and QTextEdit.

If you think, "Too basic for me", then see if you know the answers to these questions:
- How do to show an image on the screen?
- How do you prevent other people from seeing the password your user is typing in?
- How do you get your hands on the text selected in a QTextEdit?
- Will QTextEdit perform well if you add say 100 new lines to it every second?

In this episode, Jesper will answer those and many other questions.

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.
