Method Detail

execute

public void execute(java.lang.String actionCommand)

Description copied from interface: IExtension

This method is executed when the user clicks on any of the controls associated with this extension (menus, tools, etc).

Specified by:

execute in interface IExtension

Parameters:

actionCommand - An String specifying the action to execute. This is useful when there are different controls associated with the same extension.

initialize

public void initialize()

Description copied from interface: IExtension

Extension's initialization code should be here. This method is called for all the extensions during Andami's initialization.

Specified by:

initialize in interface IExtension

postInitialize

public void postInitialize()

Description copied from interface: IExtension

Extension's post-initialization code should be here. This method is called for all the extensions during Andami's initialization, after initialize() has been called for ALL the extensions.

Specified by:

postInitialize in interface IExtension

Overrides:

postInitialize in class Extension

isEnabled

public boolean isEnabled()

Description copied from interface: IExtension

This method is invoked by Andami to check whether the extension (and its associated controls) is enabled or disabled. Disabled controls (menus and buttons) are shown in light grey colour, and it is not possible to click on them.

Specified by:

isEnabled in interface IExtension

Returns:

true if the extension should be enabled, false otherwise

isVisible

public boolean isVisible()

Description copied from interface: IExtension

This method is invoked by Andami to check whether the extension (and its associated controls) is visible or hidden.

Specified by:

isVisible in interface IExtension

Returns:

true if the extension should be visible, false otherwise

isVisible

public boolean isVisible(java.lang.String action)

Specified by:

isVisible in interface IExtensionQueryByAction

Overrides:

isVisible in class Extension

isEnabled

public boolean isEnabled(java.lang.String action)

Specified by:

isEnabled in interface IExtensionQueryByAction

Overrides:

isEnabled in class Extension

canQueryByAction

public boolean canQueryByAction()

Specified by:

canQueryByAction in interface IExtensionQueryByAction

Overrides:

canQueryByAction in class Extension

update

public void update(Observable observable,
                   java.lang.Object notification)

Description copied from interface: Observer

Called whenever a Observable object is changed and this Observer has registered on it to receive notifications.

Implementations of this method will be called for each simple notification or, if a complex notification is created, for each of the child notifications.

In the latter case, don't assume any ordering in the notification between this Observer and other Observers listening to the same Observable.

In a complex notification scenario, if you want to receive only the complex notification and not each of the child notifications, just implement the ComplexObserver and prepare this method implementation to handle receiving DefaultComplexNotification instances as well as direct notification objects.

Specified by:

update in interface Observer

Parameters:

observable - the observable object.

notification - the notification data.

getStatus

public IExtensionStatus getStatus()

Description copied from interface: IExtension

Gets the status of the extension, which may be queried to check if the extension has some unsaved data or some associated background tasks.

Specified by:

getStatus in interface IExtension

Overrides:

getStatus in class Extension

Returns:

An IExtensionStatus object, containing the status of this extension.
