# Qt Examples And Tutorials

A collection of code samples and tutorials are provided with Qt to help new users get started with Qt development. These documents cover a range of topics, from basic use of widgets to step-by-step tutorials that show how an application is put together.

The examples are part of the Qt packages. Visit the Downloads page for more information.

## Running the Examples

Open and run examples within Qt Creator's Welcome mode. Most of the examples run on various platforms and to search for platform-specific examples, type the platform name (or any keywords) in the search field. For example, typing `Android` in the search field lists the examples that are fully compatible with Android.

For more information about running examples in Qt Creator, visit the Building and Running an Example page.
