DisplayPersistenceDialogCommandHandler

public DisplayPersistenceDialogCommandHandler(NatTable natTable)

Create a new DisplayPersistenceDialogCommandHandler. Using this constructor the Properties instance used for save and load operations will be created. It can be accessed via getProperties() for further usage. The current state of the given NatTable instance will be used to store a default configuration.

Parameters:

natTable - The NatTable instance for which this handler is registered. If it is not null, the current state of that NatTable will be stored as default configuration. This default configuration can't be modified anymore in the opened dialog.

DisplayPersistenceDialogCommandHandler

public DisplayPersistenceDialogCommandHandler(Properties properties)

Create a new DisplayPersistenceDialogCommandHandler using the specified Properties instance.

Parameters:

properties - The Properties instance that should be used for saving and loading.

                                      NatTable natTable)

Create a new DisplayPersistenceDialogCommandHandler using the specified Properties instance. The current state of the given NatTable instance will be used to store a default configuration.

Parameters:

properties - The Properties instance that should be used for saving and loading.

natTable - The NatTable instance for which this handler is registered. If it is not null, the current state of that NatTable will be stored as default configuration. This default configuration can't be modified anymore in the opened dialog.
