title: How to launch and later terminate cmd.exe in a console window with QProcess
body: <p>I need to run a visible cmd.exe window via QProcess, and eventually terminate it. The console window for the shell has to be in the foreground and must be visible to user.</p>
  
  <p>If I start it using <code>QProcess::start()</code>, the console window never appears. If I start it using the class method <code>QProcess::startDetached()</code>, I can't use the instance method<code>terminate()</code> to terminate it.</p>
