title: How to hide cursor in QML
body: <p>I wonder how to hide cursor in QML, QT 5.7.</p>
  
  <p>I tried to use</p>
  
  <pre><code>QGuiApplication::setOverrideCursor(QCursor(Qt::BlankCursor));
  </code></pre>
  
  <p>and </p>
  
  <pre><code>app.setOverrideCursor( QCursor( Qt::BlankCursor ) );
  </code></pre>
  
  <p>But both doesn't work.</p>
  
  <pre><code>/home/QTProjects/main.cpp:13: error: invalid use of incomplete type 'class QCursor'
       QGuiApplication::setOverrideCursor(QCursor(Qt::BlankCursor));
                                                                 ^
  </code></pre>
  
  <p>And if it possible can I hide cursor within QML not on C++ side.</p>
