title: How to make all button same size in Qt Creator
body: <p>I am making a simple calculator and want all my buttons to re-size to the size of one button that I have  set. This was possible with VS2010 but I don't know how to do this in Qt Creator. I have tried using layout but no luck. Is this possible?</p>
  <ul>
  <li>I have 16 buttons in grid layout.</li>
  <li>I resize one button changing both its height and width.</li>
  <li>Now I want all buttons to conform to the same size.</li>
  </ul>
  <p>The problem I am facing is that when I use layouts, it resets the height of the button to default so I can't really create custom size of buttons?</p>
