body: <p>How do I create a drop-down widget, such as a drop-down QLabel, drop-down QTextBrowser, etc.?</p>
  
  <p>For example, I log information in a QTextBrowser, but I don't want it taking up space on the screen. So I want to be able to click a QToolbutton and have a scrollable QTextBrowser drop-down. (A QComboBox would work too, but I can't just add each event as a separate item - I need the text to wrap, not be elided. Thus a drop-down QTextBrowser.)</p>
  
  <p>Or, for example, I want a drop-down QLabel containing a picture, etc...</p>
