title: Change styling of flat QPushButton hover state (without using style sheets)
body: <p>Flat <code>QPushButtons</code> have no indication of mouse hovering. Is there a way to set the styling for the flat button hover state so that it matches the style of the normal button hover state (or something similar)? </p>

  <p>I don't want to use style sheets if it means deviating away from the default look or having to design the button styles from scratch.</p>
