Re: [Interest] the path forward - that 7 year thing - was, willy-nilly

From the Qt blog post https://www.qt.io/blog/qt-offering-changes-2020 "These changes will not have any effect on existing commercial licensing or services agreements." Now, it doesn’t talk about the notion that if you built and produced your code against a commercial license, it has to remain

Re: [Interest] the path forward - that 7 year thing - was willy-nilly

To be clear. Roland and I are talking about very different issues. To me, Qt should continue to support OS's/Compilers for the life of a Major version of Qt. if it built on Qt 5.0 it should build on that OS/Compiler in 5.15 If Qt decides that modern C++ was more important in 5.13, and the

Well. I 100% totally overthought this... and was able to implement this in about 10 lines of code using a derivation of QProgressDIalog + QtConcurrent The progress dialog, is run with windowModality set to Qt::WindowModal, I overload exec, and launch the function then call

Im working with a thirdparty lib, that I have zero control over  Essentially, on a “button click” a long running blocking function call is executed. I can safely call the function into a background thread, but I don’t want the gui flow to continue. My idea is the following, a class that takes

[Interest] Handling of ~ paths

I’m feeling really stupid right now  Ive been a Qt user for almost 20 years, and I cant believe I have never had to deal with this before. If you are working with a path, for use in QDir, QFileInfo, QFile etc etc, and the path string is using a ~, either of the form ~/foo.txt or
