    Static method for determining the status of the SfxPoolItem-pointer,

    [Return value]

    SfxItemState        SfxItemState::UNKNOWN
                        Enabled, however no further status information is available.
                        Typical for <Slot>s, which are temporarily disabled a
                        anyway but other than that do not change their appearance.

                        SfxItemState::DISABLED
                        Disabled, no further status information is available.
                        All other displayed values should be reset to the default
                        if possible.

                        SfxItemState::DONTCARE
                        Enabled but there were only ambiguous values available
                        (i.e. none that could be queried).

                        SfxItemState::DEFAULT
                        Enabled and with available values which can be queried
                        through'pState'. The type is thus by the Slot clearly
                        defined in the entire Program.
