public class JmriUserPreferencesManager
extends Bean
implements UserPreferencesManager, InstanceManagerAutoInitialize

Implementation of UserPreferencesManager that saves user interface preferences that should be automatically remembered as they are set.

This class is intended to be a transitional class from a single user interface preferences manager to multiple, domain-specific (windows, tables, dialogs, etc) user interface preferences managers. Domain-specific managers can more efficiently, both in the API and at runtime, handle each user interface preference need than a single monolithic manager.

Method Detail

setSaveAllowed

public void setSaveAllowed(boolean saveAllowed)

Description copied from interface: UserPreferencesManager

Set if saving preferences is allowed. When setting true, preferences will be saved immediately if needed.

setSaveAllowed in interface UserPreferencesManager

Parameters:

saveAllowed - true to allow saving; false to block saving

isSaveAllowed

public boolean isSaveAllowed()

Description copied from interface: UserPreferencesManager

Check if saving preferences is allowed.

setSimplePreferenceState

public void setSimplePreferenceState(java.lang.String name,

This is used to remember the last selected state of a checkBox and thus allow that checkBox to be set to a true state when it is next initialized. This can also be used anywhere else that a simple yes/no, true/false type preference needs to be stored.

It should not be used for remembering if a user wants to suppress a message as there is no means in the GUI for the user to reset the flag. setPreferenceState() should be used in this instance The name is free-form, but to avoid ambiguity it should start with the package name (package.Class) for the primary using class.

Specified by:

setSimplePreferenceState in interface UserPreferencesManager

Parameters:

name - A unique name to identify the state being stored

state - simple boolean.

getSimplePreferenceState

public boolean getSimplePreferenceState(java.lang.String name)

Description copied from interface: UserPreferencesManager

Enquire as to the state of a user preference.

Preferences that have not been set will be considered to be false.

The name is free-form, but to avoid ambiguity it should start with the package name (package.Class) for the primary using class.

Specified by:

getSimplePreferenceState in interface UserPreferencesManager

Parameters:

name - the name of the preference

Returns:

the state or false if never set

Description copied from interface: UserPreferencesManager

Used to save the state of checkboxes which can suppress messages from being displayed. This method should be used by the initiating code in conjunction with the preferenceItemDetails.

The strClass parameter does not have to be the exact class name of the initiating code, but can be one where the information is related and therefore can be grouped together with.

Both the strClass and item although free form, should make up a unique reference.

Specified by:

setPreferenceState in interface UserPreferencesManager

strClass - The class that this preference should be stored or grouped with.

item - The specific item that is to be stored

state - Boolean state of the item.

This is used to remember the last selected state of a checkBox and thus allow that checkBox to be set to a true state when it is next initialized. This can also be used anywhere else that a simple yes/no, true/false type preference needs to be stored.
