Qt Demonstrations
This is the list of demonstrations in Qt's demos directory. These are larger and more complicated programs than the Qt Examples and are used to highlight certain features of Qt.
If you are new to Qt, and want to start developing applications, you should probably start by going through the Tutorial.
Painting
- Composition Modes demonstrates the range of composition modes available with Qt.
- Vector Deformation demonstrates effects that are made possible with a vector-oriented paint engine.
- Gradients shows the different types of gradients that are available in Qt.
- Path Stroking shows Qt's built-in dash patterns and shows how custom patterns can be used to extend the range of available patterns.
- Affine Transformations demonstrates the different affine transformations that can be used to influence painting operations.
- Arthur Plugin shows the widgets from the other painting demos packaged as a custom widget plugin for Qt Designer.
Item Views
- Interview shows the same model and selection being shared between three different views.
- Spreadsheet demonstrates the use of a table view as a spreadsheet, using custom delegates to render each item according to the type of data it contains.
SQL
- Books shows how Qt's SQL support and model/view integration enables the user to modify the contents of a database without requiring knowledge of SQL.
- SQL Browser demonstrates a console for executing SQL statements on a live database and provides a data browser for interactively visualizing the results.
