QDoc qdoc command in qtbase builds the documentation and is included in standard Qt 5 installations. The official Qt documentation is built using Linux based machines, requiring libraries needed for building Qt 5 and tested on the supported desktop platforms. Important: From Qt version 5. See also Installing Clang for QDoc. If LLVM is not installed or not found in the package tree of your system, QDoc will not be built and you will not be able to build documentation.

For the standard installation of the Qt 5 repository qt5. In many cases, building all of Qt 5 is not necessary. These are both located in the qttools repository. QDoc and qhelpgenerator depend on several Qt modules from qtbase. After the configuration step, build qtbase:. For shadow builds, the source directory and install directories are different and the global templates need to be moved to the install directories.

To do so, run:. The Qt modules have their documentation built by running make docs in the command line once Qt 5 is built and installed. QDoc builds are specified in qdocconf files which tells QDoc where to look and how to set up documentation. To run QDoc, pass the qdocconf file and the output directory as arguments. The modules have a qdocconf file in the src directory. Make sure the PATH environment variable points to the bin directory containing the qdoc3 executable.

Some Linux systems will require gmake instead of make. Jump to: navigationsearch. Categories : Developing Qt::Documentation Tools. Navigation menu Personal tools Sign in.

The installer retrieves the license attached to the account from a server and provides a list of available components corresponding to the license. The online installer is available from the Qt Downloads page. An offline installer is a single package that contains all of Qt and Add-Ons relevant for a target platform. Users with a commercial license can either sign in with their Qt account or with their Qt license key during the installation process.

The license key is available in the Qt Account Web portal.

To run the installer, you need a Qt Account. You can use your Qt Account credentials to sign-in to all Qt services, including the forums and wiki. If you do not already have a Qt Account, you can create one during the installation process.

To complete the installation, select the components that you want to install and follow the instructions of the installation program. Specific requirements and instructions for developing applications on different platforms are covered in the platform pages.

Learn the basics of Qt and Qt Quick development by following the two tutorials below that illustrate how to create simple applications and build and run them on target platforms:. Qt Widgets provides a library of UI elements which allow you to create classic desktop-style user interfaces. Qt Quick is a library providing types and functionalities for building modern, fluid, animated UIs.

Writing Qt Documentation

It may be helpful to refer to the online qdoc manual. See Troubleshooting Qt Documentation for advice on what to look for if your documentation is not processed correctly by qdoc. See Developing Qt Documentation for information about the documentation process. I'm sure I haven't found the "best" examples of documentation. These are just a few cases that I didn't consider to be in need of radical improvement.

The guidelines I learned basically followed the "pyramid" approach of providing a bit of simple information, then some more detailed information, followed by even more complex information about each class. Images are also good to include, either in terms of showing what a widget looks like or to illustrate a concept.
