Making a libgdx textfield ignore certain characters?

Question

Hi I'm stuck with a problem I don't seem able to solve regarding a TextField for libgdx. I want to ignore certain characters such as instead of writing a space in the textfield when using "shift" for a upper-case character. As of currently I've written like this.

accField.setTextFieldListener(new TextFieldListener() {

  public void keyTyped(TextField textField, char c)  {

        if (c == 'a') {
        //Something here that does the replacement maybe?                                


        }


}

});

I never worked with TextFieldFilters cause i am almost new to libgdx. But as much as i understood you use them like this:

myTextfield.setTextFieldFilter(new TextFieldFilter() {

    // Accepts all Characters except 'a' 
    public  boolean acceptChar(TextField textField, char c) {
         if (c == 'a')
               return false;
         return true;
    }
});

Hope it helps. Please tell me if it works because i want to use this TextFieldFilters to :P
