title: how to convert a SystemColors to Brush?
body: <p>I have a converter that return a Brush to set the background of a control in my view. However, when I return the SystemColors.XXX it does not work, however when I use a Brush then it works, so I am thinking that I need to convert the SystemColors to a Brush.</p>
  
  <p>How can I do it? Because I have tried this:</p>
  
  <pre><code>return (Brush)System.Windows.SystemColors.HighlightTextBrush;
  </code></pre>
  
  <p>In the resources of the control I set this:</p>
  
  <pre><code>&lt;SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" Color="Transparent"/&gt;
                  &lt;SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent"/&gt;
                  &lt;SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Black"/&gt;
                  &lt;SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightTextBrushKey}" Color="Black"/&gt;
  </code></pre>
  
  <p>I am using the transparent because the the background of the row I will set them by a multi value converter.</p>
  
  <p>thank so much.</p>
