Qt includes standard dialogs for many common operations, such as file selection, printing, and color selection.
Custom dialogs can also be created for specialized modal or modeless interactions with users.
The License Wizard example shows how to implement linear wizards using QWizard.
The Extension example shows how to add an extension to a QDialog using the QAbstractButton::toggled() signal and the QWidget::setVisible() slot.

The example also shows how to use QFileDialog to facilitate browsing, how to use QTextStream's streaming operators to read a file, and how to use QTableWidget to provide standard table display facilities for applications. In addition, files can be opened using the QDesktopServices class.
