The Eight Rules of Multithreaded Qt The biggest dos and don'ts for multi-threading in Qt
While the concept of multithreading may be straightforward, code with threads is responsible for some wicked bugs, which can be nearly impossible to reproduce or track down. This makes writing bullet-proof code using threads a tall order. Let’s look a little deeper into why that is. First, you need better than average knowledge about the […]
UiWatchDog: a keepalive monitor for the GUI thread Part of the KDToolBox series
Continuing our blog series about KDToolBox, this time we will discuss UiWatchDog, a keepalive monitor for the GUI thread. Alive? A fundamental rule when writing applications in event-driven UI frameworks such as Qt is: do not ever block the GUI thread! The GUI thread is also usually called the main thread of the application — […]
KDMacTouchBar A quick introduction
Back in February we wrote about our work to add ‘MacOs touch bar‘ support to Qt. Between then and now, support has been added in QtCreator: However, the changes have not been integrated upstream in Qt, which means there is still no easy way to add support to your own applications. KDAB is happy to […]

Qt 3D Synchronisation Revisited
As mentioned in the previous article in this series, Qt 3D 5.14 is bringing a number of changes aimed at improving performance. Most people familiar with Qt 3D will know that the API is designed around the construction of a scene graph, creating a hierarchy of Entities, each of them having having any number of […]
Qt 3D: One too many threads or what has changed in 5.14
Qt 3D makes heavy use of threads, as a way to spread work across CPU cores and maximize throughput, but also to minimize the chances of blocking the main thread. Though nice on paper, the last case eventually leads to added complexity. Sometimes, there are just one too many threads. In the past, we’ve been […]
