title: How to start application(path with space) using QProcess on mac OSX?
body: <p>It goes well when using QProcess to start a program if its path without space.<br>
  eg:</p>
  
  <pre><code>QProcess app;
  app.startDetached("open /Users/test/Desktop/MyTest/Hello.app");
  </code></pre>
  
  <p>But, it doesn't work if the program path containing spaces.<br>
  eg:            </p>
  
  <pre><code>QProcess app;
  app.startDetached("open /Users/test/Desktop/My Test/Hello.app");
  </code></pre>
