A curated list of awesome tools, libraries, and resources for the Qt framework.
Qt is a powerful cross-platform application development framework, for use primarily (but not exclusively) in C++. It's great for GUI applications, but can be used for many other things as well.
Contributions are welcome!
The official website for the Qt 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:
If you build it, they will come. This section describes aggregations of Qt users who share knowledge and code with one another. The most popular and active communities are listed in this section, but you can find a more comprehensive list here (that includes several in other languages) if you'd prefer.
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](https://forum.qt.io).
A good developer writes his or her own tools. A great one uses tools others wrote. This section will help you be great; more formally, this section details applications that make it easier to create software with Qt. You may also be interested in the Libraries section.
Don't forget about Qt's mobile support!
The Qt framework has surprisingly many tools that don't get the spotlight. This section describes them (as well as the star players that do). For the purpose of this section, "tool" refers to Qt-centric utilities whose code does not get embedded within your application (but their output might).
macdeployqt :octocat: - Generates macOS application bundles for Qt projects.qtdiag :octocat: - Command-line tool that prints out a lot of information pertaining to both your Qt installation and your system in general. No link because there's no dedicated web page; just run qtdiag on the command line. Excellent for troubleshooting.qmleasing :octocat: - Lets you make easing curves suitable for QML, though if you understand the underlying math there's no reason you couldn't use the resulting numbers elsewhere.Dependency manager for Qt / C++.
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.moc that's binary-compatible with Qt's version.windeployqt and macdeployqt tools but for Linux.This section describes software that enables creation of Qt software in a primary language other than C++. Libraries that allow run-time scripting in a Qt application are listed under Integrations.
This section describes two kinds of third-party libraries; those that provide their own brand-new functionality (e.g. widgets, dealing with particular file formats), and those that provide integrations with existing software (e.g. scripting languages, clients for REST APIs, implementations of established protocols).
For the purpose of this section, an "Integration"-focused library does one of the following:
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.
Chart generation framework. Commercial.
For fans of the ribbons that Microsoft uses in their software. Commercial.
moc.The most well-known aggregation of Qt-centric libraries out there. A package manager is also available [here](https://inqlude.org/get.html).
Another Qt-centric package manager. If you want to see the offerings without using QtPods, the full list is available [here](https://github.com/qt-pods/qt-pods-master/blob/master/pods.json), and can be added to by submitting a pull request.
Despite the name, Linux-Apps.com aggregates a wide variety of Qt-based tools and libraries for both end-users and developers.
Ubuntu users who are hesitant to install anything outside of their package managers can obtain any recent version of Qt from these repositories. Instructions for adding them are found within.
If the Libraries section doesn't satisfy you, perhaps one of these will.
Official aggregation of first-party and third-party Qt-related blogs.
Qt-centric software consulting firm with a really neat blog. Specializes in graphics applications.
Another software consulting firm that also contributes code to Qt. They seem to specialize in Qt's core architecture.

A framework is only as great as the software that uses it. Fortunately, much great software uses Qt.
There's also an official showroom here, which lets developers submit their own Qt-powered applications for display.
There's no reason you can't use C++ libraries that weren't designed for Qt. Sometimes they might even suit your needs better than what Qt offers.
Same goes for C libraries; might wanna brush up on those RAII techniques while you're at it.
If you're not using qmake for your project, you're likely using CMake instead.
Qt is commonly used for graphics applications, even providing its own wrappers around OpenGL.
If you're familiar with Awesome, you'll know that there's an extremely wide variety of resources, the usefulness of which will depend on your project. However, if you're developing Qt applications, you'll almost certainly want to look at these as well.
