Dialogs are explored next, we look at QDialog and how to build your own custom dialog class from scratch, QDialogButtonBox, QMessageBox, QFontDialog, QFileDialog, QInputDialog and how they add a layer of interactivity to your Qt GUI applications.
We then go on and explore how to work with the Qt Resource System, Styling your Qt applications with QStyle, QPalette and Style Sheets, Saving your application settings with QSetting, Working with Files and Directories using QFile and QDir and we wrap up the course with a tour of the network capabilities of Qt.
