I spawn a process that performs a lengthy operation, and I’d like to give visual feedback that something is happening, so I want to change the cursor to busy and restore it when I receive the QProcess::finished signal.

    Qsiris solution is “widget wide”. If you want to change cursor for your whole application then use 

    QApplication::setOverrideCursor(Qt::WaitCursor);

    and

    QApplication::restoreOverrideCursor();

    Note: As @Ehsan Khodarahmi pointed out, the cursor will NOT change until triggering next QT event or calling QApplication::processEvents() manually.
