title: In C#, WPF, could I hide my cursors in all windows?
body: <p>everyone.</p>
  
  <p>When I develop an application using C#, WPF. I want to hide my cursor in some special area. No matter which application/window on top, the cursor is always hiding.</p>
  
  <p>In WPF Window, normally, we use </p>
  
  <pre><code>this.Cursor = System.Windows.Input.Cursors.None;
  </code></pre>
  
  <p>But this one could not solve my problem.</p>
  
  <p>I want this situation:</p>
  
  <p>I open my window, the cursor disappears in my window. And then I open a notepad on top of my window, the cursor disappears in the notepad too.</p>
  
  <p>This one is able to do or not? Thank you.</p>
