title: Qt: Drop-down button?
body: <p>How can I create a "drop down button" in Qt?</p>
  
  <p>For a non-Qt example, see:
  <a href="https://stackoverflow.com/questions/4318837/combination-button-dropdown-in-office">Combination button/dropdown in office</a></p>
  
  <p>The key point is that the widget needs an icon for the primary action, and a visually separate "pulldown arrow" to show secondary icons / actions. </p>
  
  <p>Upon clicking the "pulldown arrow" for secondary options, the user should be presented with a grid of other icons to choose from.   (All icons, no text.)</p>
  
  <p>Does Qt have a widget that can do this?</p>
  
  <p>If not, how can this be created in Qt?  (I'm a new Qt user, so a Qt Designer based solution would be ideal.)</p>
  
  <p>Thank you</p>
