main question: is there a qtaccessiblewidgets4.dll publicly available and redistributable?
Explanation: in these years I have encountered many programs with QT4 GUI - the old Calibre, SPFlashTool (familiar to Android modders), Lightscreen, Lazesoft Recovery Suite, and others that I forgot - for which putting that DLL in a folder called "accessible" in their main path magically turns them from completely inaccessible to at least usable... but I got this DLL from an old Kindle for PC installation, so it obviously signed by Amazon LLc, that sounds very bad for my previous question. 😅
If there is a way to compile a generic version, I'm thinking, maybe we could make an add-on for this situation, or even include it in NVDA directly, like which was done for JAB...
I know that with QT5 the situation is better, but in my experience QT4 is still largely present and, unfortunately, often in software quite specialised.
Just a thought...
