Awesome Qt

Cross-platform application framework.

Official Qt documentation. Massive and comprehensive.

The best of Qt, straight to your spam filter.

If you think you've found a bug with Qt or one of its related projects, report it here (or see if someone else already has).

See how the Qt maintainers ensure their code is well-written.

Browse the various source trees that comprise the Qt project. Has mirrors at several GitHub organizations:

Mailing lists for users and developers of Qt alike. Arguably the best place to communicate directly with Qt's maintainers. Sees frequent activity.

If e-mail's not your thing, then you might also consider getting help or sharing knowledge on the forums.

The premier source for user-contributed Qt knowledge.

For real-time chat with other Qt developers and users. The most popular channels are on Freenode, and include #qt, #qt-quick, #qt-creator, and #qt-chat.

Not to be confused with the official Qt forum.

octocat:](https://github.com/qtproject/qt-creator) - By no means does Qt lock you into its provided IDE, but its firm integration with the framework makes it a good sell. Among other things, it provides a UI designer, modeling tools, a documentation browser, and great QML support if you're into that sort of thing. There's also a plugin system, but third-party plugins are unfortunately scarce.

octocat:](https://github.com/qt/qttools/tree/dev/src/designer) - If you'd rather just design the interfaces and let someone else hook them up to logic, the GUI designer is available as a separate application.

octocat:](https://github.com/qt/qttools/tree/dev/src/assistant) - So is the documentation viewer, for that matter.

octocat:](https://github.com/qt-labs/vstools) - If you'd rather stick to Visual Studio, this add-in will let you do that.

octocat:](https://github.com/qt/qttools/tree/dev/src/linguist) - Qt provides excellent internationalization/localization support, and this tool is very much responsible for it. Write translatable strings in your code with special macros, and this tool will aggregate them all for you so you or your translator(s) can broaden your software's audience.

octocat:](https://github.com/qtproject/installer-framework) - Nobody seems to talk about this, but Qt also provides a way to write an installer for your application. Does not support creation of macOS disk images, app bundles, or Linux packages, so be mindful of that when considering your project's distribution.

octocat:](https://github.com/qt/qttools/tree/dev/src/macdeployqt) - Generates macOS application bundles for Qt projects.

octocat:](https://github.com/qt/qtbase/tree/dev/qmake) - The bundled build system designed for Qt, though it can be used for non-Qt projects.

octocat:](https://github.com/qt-labs/qbs) - If QML is more your style, consider this alternative build system.

Don't forget about Qt's mobile support!

octocat:](https://github.com/Kitware/CMake) - General C++ build tool that happens to have great Qt support.

octocat:](https://github.com/KDAB/GammaRay) - Powerful debugger and general inspection tool for Qt-built software. Lets you inspect and manipulate the QObject hierarchy, view object properties, edit widgets at runtime, and far, far more. A two-sentence blurb can't do it justice, seriously check it out.

package:](https://www.riverbankcomputing.com/hg/sip) - Generates Python bindings for C or C++ libraries. Has special support for Qt signals and slots, and was used to create PyQt.

package:](https://www.riverbankcomputing.com/software/pyqt/download5) - Arguably the most comprehensive and well-known binding of Qt to another language.

package:](https://code.qt.io/cgit/pyside/pyside.git) - Another binding for Python, which has been officially adopted by the Qt project.

octocat:](https://github.com/ring-lang/ring/tree/master/extensions/ringqt) - I've never heard of this language either, honestly.

octocat:](https://github.com/xiangxw/mupdf-qt) - Qt wrapper for the MuPDF PDF viewer.

package:](https://sourceforge.net/projects/pythonqt) - Script your Qt applications with Python. Not to be confused with PyQt or PySide.

package:](https://www.riverbankcomputing.com/software/qscintilla/download) - Absurdly versatile and customizable text editor widget that provides syntax highlighting, code completion, code folding, recordable macros, and much more. Built around Scintilla. Created by the same company that developed PyQt.

package:](https://svn.savannah.nongnu.org/viewvc/?root=libqtlua) - Use Lua as a scripting language for Qt-based software.

package:](https://sourceforge.net/projects/quazip) - Read from and write to ZIP archives. Uses Minizip under the hood.

octocat:](https://github.com/vlc-qt/vlc-qt) - Wrapper for libvlc that lets you add a VLC-like media player to your application.

octocat:](https://github.com/communi/libcommuni) - Cross-platform IRC framework. We've got enough IRC clients out there already, but I suppose this could also be used to implement a chat function in your application (e.g. for community support).

octocat:](https://github.com/cutelyst/cutelyst) - Web framework that takes some ideas from Perl's Catalyst framework.

Cross-platform game engine and app framework that relies heavily on QML. Has a lot of tools and resources, and may even deserve its own list.

octocat:](https://github.com/KDE) :package: - Metric ass-ton of libraries for KDE, but many of them can be used with regular Qt applications as well. Cross-platform, for the most part.

package:](https://cgit.kde.org/marble.git) - Virtual globe and map that can be used standalone or embedded within other applications.

octocat:](https://github.com/wang-bin/QtAV) - Actively developed multimedia framework.

octocat:](https://github.com/JPNaude/Qtilities) - Powerful set of libraries that provide GUI, logging, testing, configuration, and project functionality (among other things) for your application.
