Qt includes a set of examples that cover nearly every aspect of Qt development. They aren't meant to be impressive when you run them, but in each case the source code has been carefully written to illustrate one or more best Qt programming practices.
You can run the examples from the Examples and Demos Launcher application (except see QML 范例 for special instructions for running those examples). In addition, Qt Creator can directly run these examples through the Welcome Page.
The examples are listed below by functional area. Each example listed in a particular functional area is meant to illustrate how best to use Qt to do some particular task in that functional area, but the examples will often use features from other functional areas as well for completeness.
If you are new to Qt, you should probably start by going through the 教程 , and then begin with the 应用程序 范例。
In addition to these examples and the 教程 , Qt includes a selection of demos that deliberately show off Qt's features. You might want to look at these as well.

The QML 范例和演示 site has a dedicated page for QML examples.
The Qt Mobility Examples page lists examples that show how the Qt Mobility APIs might be used.
