public abstract class AbstractHoverInformationControlManager extends AbstractInformationControlManager
MouseTrackListener on the manager's subject
control. The manager has by default an information control closer that closes
the information control as soon as the mouse pointer leaves the subject area,
the user presses a key, or the subject control is resized, moved, or
deactivated.
When being activated by a mouse hover event, the manager disables itself, until the mouse leaves the subject area. Thus, the manager is usually still disabled, when the information control has already been closed by the closer.
