A very common implementation pattern for QObject subclasses is to declare its child QObjects as data members of type “pointer to child.” Raise your hand No, keep your hand on your computer input device 🙂 Nod if you have ever seen code like this (and maybe even written code like this yourself): A fairly common […]

Einleitung Der ESE Kongress ist die Leitveranstaltung für Embedded Software Engineering in Deutschland. In diesem Jahr fand er erstmals digital statt, so dass die Teilnahme auch per Video möglich war. An fünf Tagen gab es 3 Keynotes und 96 Fachvorträge aus allen Bereichen der Embedded Softwareentwicklung. Anton Kreuzkamp von KDAB sprach über maßgeschneidertes Code-Refactoring mit […]
Some time ago, I wrote about how to build C++ projects with ASAN on Windows. Now, if you happen to deal with Qt projects you may want to take this one step further and sanitize Qt itself. Why bother with a sanitized Qt build? Let’s have a closer look on why having a sanitized Qt […]
Memory bugs are tricky. Leaks have a clear impact on performance, and quickly become hard to spot when heap allocated objects move too much. Memory access bugs, on the other hand, make your program crash right away, if you’re lucky. In less desirable cases, they may end up corrupting random objects on the heap, and […]
Clang-Tidy, part 2: Modernize your source code using C++11/C++14. The blog series introduces you to the clang-tidy utility and how to use it to automatically refactor C++ source code and integrate it with your build system.
In the previous episode we presented how to uncover 32 Qt best practices at compile time with clazy. Today it’s time to show 5 more and other new goodies present in the freshly released clazy v1.2. New checks 1. connect-not-normalized Warns when the content of SIGNAL(), SLOT(), Q_ARG() and Q_RETURN_ARG() is not normalized. Using normalized […]
This blog series will introduce the clang-tidy utility from the Clang/LLVM project and show how to use it to automatically refactor
