Automating tasks in Qt Creator
My first project when I entered KDAB was the migration of a multi-million lines Motif application to Qt… feels quite scary said like that. Fortunately, migrations from any toolkit to Qt is something KDAB has been doing from the beginning, and has lots of experience with. You may be wondering what this has to do […]
Why is my screen still black A digestible blog on common render issues and what their cause could be
Part 2 If you are here from Part 1, welcome back. If you are wondering why we started at Part 2, go to Part 1. So, you tried everything from the first part (that was relative to you), and your screen is still a backlighting test? No problem. (Well.. I mean, clearly there is but […]

Still… waiting. It says it’s done but, nothing. Well, maybe not nothing but simply darkness. You stare into the deep dark […]
Qt, range-based for loops and structured bindings Part 1
Qt has a long history. The first stable version was released before the first version of C++ was standardized and long before the different C++ compiler vendors started shipping usable implementations of the C++ standard library. Because of this, Qt often followed (and still follows) some design idioms that feel unnatural to the usual C++ […]
Ideas to help working from home
When I came to KDAB to work, working at home was a bit of a culture shock for me – I’d previously only ever worked in an open-plan office and had sworn that home working was not for me – I’d never manage to get anything done! However, I’ve found that home working suits me […]
Debugging and Profiling Qt 3D applications Learn about new 5.15 features and other useful tools
