I have a GUI application, which creates a QProcess inside, catches its output and shows it on a form. I need to somehow catch key events from the form to pass them to QProcess (to make it fell as close as possible to real terminal window). So, I suppose, I should process keyReleaseEvent() and somehow transform either event.text() (which...

If a program uses no std...

I've run into a weird error with a Qt program running on Windows. The program uses QProcess to spawn a child process wit two arguments. The program and arguments passed to the QProcess::start() method are of the form: "batchfile.bat" "--option1=some_value" "--option2=some_other_value\with_a\path" For some reason by the time those op...
