This is Qt Creator 4.12. I have worked with Visual Studio for many years, so every IDE get compared to VS. QtCreator does the job as an editor, but it suck as a debugger. Even STM32CubeIDE that uses the same GDB is far better that Qt Debugger. And working with QML you might want to try Qt’s Graphical Designer – One advice – don’t bother!
Myself I found it easier to deal with QML through a text editor than trying their buggy Graphical Designer. Don’t take me wrong – I actually use QtCreator on QML. It exist a Visual Studio Integration, but I have yet to see the advantage of that as it is not a full VS integration.
Judgement on QtCreator ? It gets the job done and it’s better than nothing!
