title: Qt Stylesheet. Background-color, YES. background-image, NO
body: <p>It's a weird problem with stylesheets: I have a window, child of class QWidget. I apply a stylesheet to it to ideally change the background of the entire window to an image with a repeat-x and repeat-y, tiling it.</p>
  
  <p>The stylesheet "pipeline" works. If I use "background-color" and set it to say, red, the entire window will be painted red. however, if I use the background-image, it does not. if i add a CHILD WIDGET (using Qt-Designer) inside the window, the background-image will work, just inside that child widget, but not outside of it, all over the parent window. </p>
  
  <p>Obviously I am doing something wrong, but am really clueless as to why  the background-color would work on the entire window, but the background-image won't, unless there's a child widget, and then, only inside of it. </p>
