getFileHistory

public java.lang.String[] getFileHistory()

Get the opened files history list.

getProjectHistory

public java.lang.String[] getProjectHistory()

Get the opened project files history list.

getWorkspaceHistory

public java.lang.String[] getWorkspaceHistory()

Get the opened wokspace files history list.

getHistoryCount

public int getHistoryCount()

Get the maximum number of entries in the history list. The same maximun is used for the file, project, and workspace history. The default value is 4.

setHistoryCount

public void setHistoryCount(int count)

Set the maximum number of entries in the history list. The same maximun is used for the file, project, and workspace history. The default value is 4.

save

public void save()

Save the opened file history. The history is saved in the Ide.properties file.

handleEvent

public boolean handleEvent(IdeAction action,
                           Context context)

Description copied from interface: Controller

This method is called when a user interaction with a View triggers the execution of a command.

Specified by:

handleEvent in interface Controller

Parameters:

action - action whose command is to be executed.

Returns:

true if the controller handles the specified command.

update

public boolean update(IdeAction action,
                      Context context)

Description copied from interface: Controller

This method updates the enabled status of the specified action within the specified context. It should generally be called on the controller associated with the active view to allow that controller to take the first crack at determining its enabled status. If that controller wants to update its enabled status, it does so and returns true to indicate that further controllers do not need to be consulted. If the controller does not deal with setting the enabled status of an action, it delegates the request to its supervising controller, all the way up to the Ide. The Ide has a special implementation of update(xx) that further delegates the request to root controllers, until one of them returns true indicating the request was handled by the controller.

Specified by:

update in interface Controller

Parameters:

action - action whose command is to be executed.

context - the current context

Returns:

true if the controller handles the specified command.

initialize

protected void initialize()

getOpenedFiles

protected HistoryList getOpenedFiles()

getOpenedProjects

protected HistoryList getOpenedProjects()

getOpenedWorkspaces

protected HistoryList getOpenedWorkspaces()
