title: How to keep both cursor and PlaceholderText displayed at the same time in a QLineEdit?
body: <p>I have a <code>QLineEdit</code> with a <code>PlaceholderText</code>.</p>
  
  <p>I want to clear the <code>PlaceholderText</code> only when a person starts typing, else the blinking cursor and <code>PlacehoderText</code> both should be there in that <code>QLineEdit</code>.</p>
  
  <p>It is the first field of the page, so I have set the focus to this <code>QLineEdit</code>, but the <code>PlaceholderText</code> disappears as soon as this page is displayed.</p>
  
  <p>Please suggest if I'll have to add a SIGNAL/SLOT for this <code>QLIneEdit</code>, so that the <code>PlaceholderText</code> doesn't get cleared off.</p>
