TableListBox inherited class: How to intercept mouse wheel?

My class ID3View, which inherits from TableListBox, should be able to intercept mouse wheel messages. How can I do that?

When I use void mouseWheelMove ( const MouseEvent & e, float wheelIncrementX, float wheelIncrementY), this function gets only called when there are no ScrollBars showing in the ListBox.

Why is it that way? How can I do it?
