Hi all

i have added a Popup menu on a Jtable.
i have to enable or disable based on selection or rows.

like i have to enable or disable some menu item if selection is only one row.
and the menu item's state is different if selection is multiple.

and also based on different parameter.

i am tiered of adding logical operations checking conditions. every time new menu is added.

is any design pattern to achieve this.?

Thanks

GoF's Strategy Pattern sounds to suit your problem - or State pattern should also be checked.
If you could post a SSCCE, that would make it easier to help too.
