With a lot of thanks to Jörg's effort, since Qt 5.9 we have a non-static startDetached() method, which do honour the environment set with setProcessEnvironment, the current working dir with setWorkingDirectory, etc.
I think it's a far superior option. By far, it avoids the mistake that led to QTBUG-74074, where someone wrote: QProcess exeB; QProcessEnvironment env = QProcessEnvironment::systemEnvironment(); env.insert("PYTHONHOME", "NewVariable"); exeB.setProcessEnvironment(env); exeB.startDetached("AnotherProcess/AnotherProcess.exe"); Unfortunately, that startDetached is static, so the setting made in the object are not relevant. The author needed to write: exeB.setProgram("AnotherProcess/AnotherProcess.exe"); exeB.startDetached(); Ok to deprecate it? We will not be able to recover those overloads in Qt 6, but we may be able to bring them back in Qt 7. Alternative: deprecate *ALL* startDetached() overloads and instead add a setDetachedMode(bool enable), and allow start() to start detachedly. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel System Software Products _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
