Question

I am trying to capture the onclick event from a textcell. why does not this fire the click event –

        TextCell tempCell = new TextCell() {
            @Override
            public void onBrowserEvent(Cell.Context context, Element parent, String value, 
                    NativeEvent event, ValueUpdater<String> valueUpdater) {
                 if ("click".equals(event.getType())) {
                     Window.alert("Clicked me from cell");
                 }
            }
        };
        Column<Contact, String> tempColumn = new Column<Contact, String>(tempCell) {
          @Override
          public String getValue(Contact object) {
            return object.address;
          }


        };
        table.addColumn(tempColumn, "Address");

This will not work because TextCell does not consume any events. You must sub-class AbstractSafeHtmlCell instead and tell it which events you want to consume by passing them into the constructor.

This will do:

private class MyTextCell  extends AbstractSafeHtmlCell<String> {

 /**
  * Constructs a TextCell that uses a {@link SimpleSafeHtmlRenderer} to render
  * its text.
  */
  public MyTextCell() {
    super(SimpleSafeHtmlRenderer.getInstance(), "click");

  }



  @Override
  public void render(Context context, SafeHtml value, SafeHtmlBuilder sb) {
    if (value != null) {
      sb.append(value);
    }
  }

  @Override
  public void onBrowserEvent(Context context, Element parent,
        String value, NativeEvent event,
        ValueUpdater<String> valueUpdater) {
    GWT.log("Click event!!!!!! Not listening to anything else");
  }
}
