title: How to use qrc resources in qss in qtdesigner?
body: <p>I need to create QLineEdit with the search icon on the left side and i'm doing it in QtDesigner. </p>
  
  <p>I've added my search_icon.svg to my resources.qrc file and assigned this qrc as a resource of my application using resource browser of QtDesigner. The contents of resources.qrc look like this: </p>
  
  <pre><code>&lt;RCC&gt;
    &lt;qresource prefix = "/icons"&gt;
      &lt;file alias = "search_icon.svg"&gt;search_icon.svg&lt;/file&gt;
    &lt;/qresource&gt;
  &lt;/RCC&gt;
  </code></pre>
  
  <p>Then I referenced search_icon.svg in "Edit Style Sheet" window of QtDesigner using qss:</p>
  
  <pre><code>QLineEdit {
      background-image: url(:/icons/search_icon.svg);
      background-position: left;
      padding: 2 2 2 25;
  } 
  </code></pre>
  
  <p>but search_icon.svg hadn't been displayed on QLineEdit.</p>
  
  <p>QtDesigner's mainWindow.ui and resources.qrc as same as search_icon.svg are in the same directory. </p>
  
  <p>Do I need to compile resources.qrc somehow so that search_icon.svg can be used in qss of "Edit Style Sheet" window of QtDesigner?</p>
