Yahoo YUI 2 - Rich Text Editor - how do I change the titlebar of the Editor to another string value?

I'm using the Yahoo YUI 2 rich text editor. I would like to change the titlebar of the editor window from its default value of "Text Editing Tools" to a different value... one that fits with the page the editor is placed on.

I saw this example from the YUI 2.x Forum -

myEditor.toolbar.set('titlebar', 'Foo');

But that doesn't work for me.

My 开发者_开发问答editor is created like this -

        var OpeningTextEditor = new YAHOO.widget.Editor('OpeningText', {
            height: '300px',
            width: '522px',
            dompath: false, //Turns on the bar at the bottom
            animate: false, //Animates the opening, closing and moving of Editor windows
            handleSubmit: true                
        });

            //***** T H I S   L I N E   D O E S N'T   W O R K ******
            //OpeningTextEditor.toolbar.set('titlebar','Opening Text');

        OpeningTextEditor.render();

Is there something wrong with the syntax? I don't know why else it wouldn't work....

Either of these seem to work:

OpeningTextEditor.get('toolbar').titlebar = 'Opening Text';

or

OpeningTextEditor._defaultToolbar.titlebar = 'Opening Text';
