Constructor Detail

AbstractProject

public AbstractProject()

Creates a new instance.

Method Detail

init

public void init()

Description copied from interface: Project

Initializes the project. This is invoked right before the application shows the project. A project must not consume many resources before method init() is called. This is crucial for the responsivenes of an application.

Specified by:

init in interface Project

setApplication

public void setApplication(Application newValue)

Description copied from interface: Project

Sets the application of the project. By convention, this is only invoked by Application.addProject() and Application.removeProject(). This is a bound property.

Specified by:

setApplication in interface Project

getApplication

public Application getApplication()

Description copied from interface: Project

Gets the application to which this project belongs.

Specified by:

getApplication in interface Project

getComponent

public javax.swing.JComponent getComponent()

Description copied from interface: Project

Returns the visual component of the project.

Specified by:

getComponent in interface Project

getFile

public java.io.File getFile()

Description copied from interface: Project

Returns the project file.

Specified by:

getFile in interface Project

setFile

public void setFile(java.io.File newValue)

Description copied from interface: Project

Sets the project file. This is a bound property.

Specified by:

setFile in interface Project

getOpenChooser

public javax.swing.JFileChooser getOpenChooser()

Gets the open file chooser for the project.

Specified by:

getOpenChooser in interface Project

createOpenChooser

protected javax.swing.JFileChooser createOpenChooser()

getSaveChooser

public javax.swing.JFileChooser getSaveChooser()

Gets the save file chooser for the project.

Specified by:

getSaveChooser in interface Project

createSaveChooser

protected javax.swing.JFileChooser createSaveChooser()

hasUnsavedChanges

public boolean hasUnsavedChanges()

Returns true, if the project has unsaved changes. This is a bound property.

Specified by:

hasUnsavedChanges in interface Project

setHasUnsavedChanges

protected void setHasUnsavedChanges(boolean newValue)

dispose

public void dispose()

Gets rid of all the resources of the project. No other methods should be invoked on the project afterwards.

Specified by:

dispose in interface Project

getAction

public javax.swing.Action getAction(java.lang.String id)

Returns the action with the specified id.

Specified by:

getAction in interface Project

putAction

public void putAction(java.lang.String id,
                      javax.swing.Action action)

Puts an action with the specified id.

Specified by:

putAction in interface Project

execute

public void execute(java.lang.Runnable worker)

Executes the specified runnable on the worker thread of the project. Execution is perfomred sequentially in the same sequence as the runnables have been passed to this method.

Specified by:

execute in interface Project

setMultipleOpenId

public void setMultipleOpenId(int newValue)

Description copied from interface: Project

Sets the multiple open id. The id is used to help distinguish multiply opened projects. The id should be displayed in the title of the project.

Specified by:

setMultipleOpenId in interface Project

getMultipleOpenId

public int getMultipleOpenId()

Description copied from interface: Project

Returns the multiple open id. If a project is open only once this should be 1.

Specified by:

getMultipleOpenId in interface Project

setShowing

public void setShowing(boolean newValue)

Description copied from interface: Project

This is used by Application to keep track if a project is showing.

Specified by:

setShowing in interface Project

isShowing

public boolean isShowing()

Description copied from interface: Project

This is used by Application to keep track if a project is showing.

Specified by:

isShowing in interface Project

Overrides:

isShowing in class java.awt.Component

markChangesAsSaved

public void markChangesAsSaved()

Description copied from interface: Project

Marks all changes as saved. This changes the state of hasUnsavedChanges to false.

Specified by:

markChangesAsSaved in interface Project
