/**
    @class wxMouseState

    Represents the mouse state.

    This class is used as a base class by wxMouseEvent and so its methods may
    be used to obtain information about the mouse state for the mouse events.
    It also inherits from wxKeyboardState and so carries information about the
    keyboard state and not only the mouse one.

    This class is implemented entirely inline in @<wx/mousestate.h@> and thus
    has no linking requirements.
