KDAB’s Kevin Funk presented Using Modern CMake with Qt at Qt Virtual Tech Con last month.

He reported that the Qt Company did a great job moderating the sessions at this event, and there was a lively Q&A at the end – Kevin had to pick from about 60 questions, so this is a hot topic.

Now the event is over you can access Kevin’s talk here, including the answers he had time for, and also his slides, below the abstract.

Using Modern CMake with Qt with Kevin Funk

Prerequisite: No prior CMake experience required

CMake is a cross-platform build system, with powerful APIs for finding dependencies of various or specific versions, and with many abstractions for platforms, compilers, other build systems, and dependencies.

The next major Qt version, Qt6, will be using CMake internally as its build system, so the CMake integration with Qt will likely get tighter and more versatile in the long-term.

In this talk, we’ll be introducing Qt specific CMake functionalities, in order to find and use Qt5 inside your personal CMake-based project, using modern CMake capabilities. We are going to discuss how to find Qt installs using CMake’s find_package function and how to find specific Qt versions when multiple versions are installed.

Further than that, useful CMake variables such as CMAKE_INCLUDE_CURRENT_DIR, CMAKE_AUTOMOC, CMAKE_AUTORCC, and CMAKE_AUTOUIC will be explained in detail and how the use of the CMake integrations can speed up the build drastically.

Last but not least some of the additional supplied Qt related CMake functions, such as for big resources or translation support will be discussed.

Target audience: Build Engineers or Software Engineers who would like to know more about using Qt under CMake.

Multithreading in Qt with Jim Albamont

Prerequisite: Knowledge and experience programming with Qt and C++. A basic understanding of multithreaded programming is an advantage but not required.

Multithreaded programming is essential for developers to create fast and responsive applications on computers, phones, and embedded devices all with an increasing number of cores. Qt offers several mechanisms for multithreading; however, it can be difficult to know which to use and how to steer clear of common pitfalls. This course offers guidance how to write safe and efficient multithreaded code with Qt.

Topics include:
  • Basic multithreading concepts (threads, processes, data races, reentrency, shared data)
  • Synchronization primitives (mutexes, semaphores, condition variables)
  • Special concerns for Qt applications (cross-thread signals/slots, QObject thread affinity, the GUI thread)
  • Low-level multithreading with Qt (QThread, QThreadPool, QMutex, etc)
  • High-level multithreading with Qt (QtConcurrent)
  • A brief summary of atomic operations
  • Comparison between Qt and standard C++ multithreading programming

Target Audience: Qt Developers interested in multithreaded programming

About Jim Albamont

Senior Software Engineer at KDAB. Jim has actively developed with Qt since 2001. He has a background in computer graphics and data visualization, including 6 years as the lead developer of a multithreaded 3D visualization tool for financial data built with Qt and OpenGL. He has held Qt training classes throughout the US where he is based. Jim holds an MSc in Computer Science.

Introduction to Qt 3D with Mike Krus

Prerequisite: This course requires use of Qt 5.7.1 or higher and assumes prior knowledge of Qt Quick. No prior OpenGL knowledge is required.

In this course you will learn Qt 3D and its use of modern programmable shader-based pipelines which can be applied to both OpenGL and OpenGL ES.

Topics include:
  • Drawing: Geometries, Materials and Lights
  • User Input: Picking, Keyboard Handling, Logical Devices
  • Integration and Helpers: Dynamic Scenes, QtQuick Integration
  • Scene Graph: Graphics Pipeline, GLSL, Coordinate Systems, Texturing
  • Frame Graph: Viewports, Layers, Selecting Shaders at Runtime, Post-processing Effects

Target audience: Developers who want to conveniently and efficiently integrate Qt 3D.

About Mike Krus

Senior Software Engineer at KDAB. Mike has been developing with C++ since 1996 and Qt since 2004. He has a broad range of experience in scientific applications, mainly in civil engineering and oil & gas industries. His range of expertise includes C++, QML and interactive 3D visualization software design on desktop and mobile as well as macOS development. Mike is the Qt maintainer for the tvOS platform, one of the core contributors to Qt 3D and is interested in building mobile applications with Qt, mainly on iOS. He has a PhD in Computer Science.

Embedded World – 25-27 February 2020

February 2020 will be the tenth year that KDAB exhibits at Embedded World, in Nuremberg, Germany.

When we started exhibiting, there were only five halls compared to today’s seven, so the event continues to grow and remain relevant, in a world where most interaction takes place on-line. In those ten years, trends have come and gone, with the emphasis moving from medical devices to industrial equipment and ‘automotive everywhere’, while slowly but surely software has taken center stage.

Hardware is still important, but there is less and less differentiating factor in electronics and casings when creating an embedded device nowadays, so we believe only software can really give a product the edge it needs to be successful.

At our booth in Hall 4-258, we will once again demonstrate some examples of this we are proud of, using C++, Qt/QML and 3D…

C++ RussiaC++ Russia is the premier C++ conference in East Europe which alternates between Moscow and Saint Petersburg. The conference lasts for two days starting October 31st. It will be held in the Park Inn by Radisson Pulkovskaya Hotel in the heart of Saint Petersburg.

This year, the speaker line-up is quite impressive and includes names like Sean Parent, Eric Niebler, Hana Dusíková, Marshall Clow and Bryce Adelstein Lelbach.

KDAB’s Ivan Čukić will be giving the closing keynote on Friday, November 1st:

Compile-time type tagging

Many types in the standard library have additional meta-data defined in them. For example, all container types have a value_type defined which tells us the type of the items that are stored in the collection. Iterators have tags that tell us to which kind the iterator belongs to.

The problem is that this meta-information is mostly hard-coded. Sometimes this is not enough. For example, when we work with expression templates and other similar template-heavy techniques, it is useful to be able to calculate the meta-information bit by bit while the meta-program is being executed.

Since everything in a TMP program is immutable, we’ll need to use tricks to simulate mutability and step-by-step generation of the type meta-data. In this talk, we will use and explain many new C++ features like fold expressions, concepts, type lists and index sequences, and the code will extensively use move semantics to generate a cleaner assembly code for type instantiation.
