Introduction to Qt Widgets (Part 35) - File Handling

Qt offers a rather wide spectrum of classes for accessing contents of files, including reading and writing bytes to parsing XML, JSon, and CBor files. In addition to that, it also has useful API's for copying files, getting file information (like is it readable), and traversing whole directories. Learn about all that and more in this episode.

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.
