Constructor Detail

DataEditorSupport

public DataEditorSupport(DataObject obj,
                         CloneableEditorSupport.Env env)

Editor support for a given data object. The file is taken from the data object and is updated if the object moves or renames itself.

Parameters:

obj - object to work with

env - environment to pass to

Method Detail

create

public static CloneableEditorSupport create(DataObject obj,
                                            MultiDataObject.Entry entry,
                                            CookieSet set)

Factory method to create simple CloneableEditorSupport for a given entry of a given DataObject. The common use inside DataObject looks like this:

  getCookieSet().add((Node.Cookie) DataEditorSupport.create(this, getPrimaryEntry(), getCookieSet()));
 

Parameters:

obj - the data object

entry - the entry to read and write from

set - cookie set to add remove additional cookies (currently only SaveCookie)

a subclass of DataEditorSupport that implements at least OpenCookie, EditCookie, EditorCookie.Observable, PrintCookie, CloseCookie

Returns:

data object passed in constructor

messageOpening

protected String messageOpening()

Returns:

the message or null if nothing should be displayed

messageOpened

protected String messageOpened()

Message to display when an object has been opened.

Specified by:

messageOpened in class CloneableOpenSupport

Returns:

the message or null if nothing should be displayed

messageSave

                                  boolean readOnly)

Marks up a tab name according to modified and read-only status. Done for subclasses automatically in messageName() and messageHtmlName() but useful for other editor-like windows.

Behavior currently varies according to the system property nb.tabnames.html.

Parameters:

label - incoming label (null not permitted, so take care with Node.getHtmlDisplayName())

html - if true, label may include HTML markup (with or without initial <html>), and result may as well
