public Project newProject()

Description copied from interface: ProjectManager

Creates a new project.

Specified by:

newProject in interface ProjectManager

Returns:

a new, empty project

openProject

public Project openProject(String location)

Description copied from interface: ProjectManager

Opens a project from a certain location. The current plugin is used to perform this operation. The new project is returned.

Specified by:

openProject in interface ProjectManager

Parameters:

location - storage location of the project, e.g. a file path

Returns:

the loaded project or null if an error occured

saveProject

public void saveProject(Project project,
                        boolean newName)

Description copied from interface: ProjectManager

Saves a project. The current plugin is used to perform this operation (and also to determine the storage location).

Specified by:

saveProject in interface ProjectManager

Parameters:

project - the project to be saved

newName - whether the project shall be saved in a new location ('save as')

closeProject

public boolean closeProject(Project project)

Description copied from interface: ProjectManager

Closes a project. Checks whether it should be saved and whether a demo must be stopped before closing.

Specified by:

closeProject in interface ProjectManager

Parameters:

project - the project to be closed

Returns:

true, iff the project was closed

closeAll

public boolean closeAll()

Description copied from interface: ProjectManager

Closes all projects.

Specified by:

closeAll in interface ProjectManager

Returns:

true, iff all projects were closed

getActiveProject

public Project getActiveProject()

Description copied from interface: ProjectManager

Returns the currently active project (the user activates projects by selecting the frame).

Specified by:

getActiveProject in interface ProjectManager

Returns:

the project that is active or null if no project is active

setActiveProject

public void setActiveProject(Project project)

Description copied from interface: ProjectManager

Sets the currently active project. This doesn't change the active frame but follows from changing the active frame.
