title: QTableWidget vs QTableView
body: <p>I am new to this Model/View Framework of Qt. In my application I want to have 1000 X 1000 cells. There should be minimum memory requirement &amp; it should be fast. I don't know what this Model terminology is for. But I have my own class which knows how to deal with the  double variables stored in the table. Currently I am using QLineEdit's with a Validator to create the array of cells. But it was way too slow for cells > 50 X 50. So I decided to go the good old MS Excel way.</p>
  
  <p>So which Widget should I use: <code>QTableWidget</code> or <code>QTableView</code>?</p>
  
  <p>And can anybody please explain in short what this Model/View framework is? I am not a Computer Science guy hence I am finding it tough to understand...</p>
