Removing Logical Operator from Filter Criteria

Hi,
I am using smart GWT-3.x.
I created a filter in my application by using the control:
Filter Builder.
I have the logical operators(Match All(AND), Match Any(OR) and Match None(NOT)).
I don't want to show the third operator(Match None) in UI.
How can I remove the third operator(Match None).
Is it possible to remove it.
Please give me a solution for this.
I have attached a screenshot for the reference.


Thanks in Advance.
