Common Model for different component

[Mahesh x Bogadi]

Hi All,

Is it possible to use same Model object to many components.

Like say I have a Model object for Name.

Can I use the same Model object with a JComboBox, JSpinner, JList, etc......?
If yes how?

Thanks

Of course you can use the same model. That model will have to implement all the different interfaces for those components however (ListModel, ComboBoxModel,...).

If you create a model that conforms to all those interfaces I see no reason why you can not use the same Object/Class in them.

Hope this helps.

Another, probably more apropriate design, would be to have a common model that isn't specific to any of the components (that is, doesn't implement any of the interfaces), and provide an Adapter for each component - an implementation of the appropriate interface that basically delegates all calls to the common model.
