title: Qt5 Double range slider
body: <p>There are many postings online about trying to make a double range slider<img src="https://i.stack.imgur.com/rBPas.png" alt="enter image description here"></p>
  
  <p>The most common answer I found is to use <code>libqxt</code>.  However, going to the <a href="http://dev.libqxt.org/libqxt/wiki/Home" rel="noreferrer">website</a>  it clearly states it is not maintained due to internal api changes with newer versions of <code>Qt</code>. </p>
  
  <p>Does <code>Qt5</code> provide any new functionality for this, or is there a longer lasting <code>Qt</code> implementation that provides this functionality without requiring large external libraries?</p>
