title: Smartgwt: How to get checkbox value on a listgrid?
body: <p>I've a listener on cellClick, I get the selected Record but I can't find a way to understand if this record is checked</p>
  
  <p>Method ListGrid.isSelected(ListGridRecord) returns true if row is selected, not if is checked</p>
  
  <p>My Code:</p>
  
  <pre><code>listGrid.setSelectionAppearance(SelectionAppearance.CHECKBOX);
              listGrid.addCellClickHandler(new CellClickHandler() {
  
                  @Override
                  public void onCellClick(CellClickEvent event) {
  
                      if(event.getColNum() == 0 &amp;&amp; idMenu != null){
                          boolean isChecked = event.getRecord().???;
  
                          if(isChecked)
                              ....
                          else
                                                      ....
          }
  </code></pre>
  
  <p>I've tried also with event.getRecord().getAttributeAsBoolean("_checkField") with no success...</p>
