protected class BasicComboPopup.InvocationMouseHandler extends MouseAdapter
A listener to be registered upon the combo box (not its popup menu) to handle mouse events that affect the state of the popup menu.

This listener also helps with click-and-drag scenarios by setting the selection if the mouse was released over the list during a drag.
