An event that is fired before the DataGrid editor is opened. Provides access to the components that will be used in the editor, giving the possibility to change their values programmatically.

Sample usage:

 dataGrid.addEditorOpenListener(event -> {
      Map<String, Field> fields = event.getFields();
      Field field1 = fields.get("field1");
      Field field2 = fields.get("field2");
      Field sum = fields.get("sum");

      ValueChangeListener valueChangeListener = e ->
      sum.setValue((int) field1.getValue() + (int) field2.getValue());
      field1.addValueChangeListener(valueChangeListener);
      field2.addValueChangeListener(valueChangeListener);
 });
