title: Setting number of rows to be displayed for Multi line text in swt
body: <p>I am using following for TextArea</p>
  
  <pre><code>ToolBar bar = new ToolBar(box,SWT.NONE);
  ToolItem item = new ToolItem(bar, SWT.SEPARATOR);
  Text text = new Text(bar, SWT.BORDER | SWT.MULTI);
  item.setWidth(width);
  item.setControl(text);
  
  GridData data = new GridData();
  data.verticalAlignment = SWT.CENTER;
  data.grabExcessHorizontalSpace = true;
  data.grabExcessVerticalSpace = true;
  text.setLayoutData(data);
  </code></pre>

  <p>Any idea how to set the number of rows to be displayed ?</p>
  
  <p>Thanks.</p>
