We have seen several requests for a Qt6 build and sources so far, and we plan to make them available. We want to ensure we can address the various users’ needs, so some details are still under internal discussion - that’s why we can’t give a precise timeline just yet.
I am a little bit out of touch, IIRC old IDA C++ SDK sources stated that C++ Qt is very unrecommended to use, and python is preferrable for Qt. Is this going be solved? This is why you are asking about Qt6, right?
I am asking as I’m indeed writing my plugins in C++ and I am using Qt in my plugins. They require C++ as I want to to do some heavy lifting. I also use some of the Qt features which are not used by Hex-Rays so I need a few extra libs.
