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)
Returns:: a subclass of DataEditorSupport that implements at least OpenCookie, EditCookie, EditorCookie.Observable, PrintCookie, CloseCookie
Since:: 5.2

getDataObject

public final DataObject getDataObject()

Getter of the data object that this support is associated with.

Returns:: data object passed in constructor

messageOpening

protected String messageOpening()

Message to display when an object is being opened.

Specified by:: messageOpening in class CloneableOpenSupport

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

protected String messageSave()

Constructs message that should be displayed when the data object is modified and is being closed.

Specified by:: messageSave in class CloneableEditorSupport

Returns:: text to show to the user

messageName

protected String messageName()

Constructs message that should be used to name the editor component.

Specified by:: messageName in class CloneableEditorSupport

Returns:: name of the editor

messageHtmlName

protected String messageHtmlName()

Overrides:: messageHtmlName in class CloneableEditorSupport

documentID

protected String documentID()

Overrides:: documentID in class CloneableEditorSupport

messageToolTip

protected String messageToolTip()

Text to use as tooltip for component.

Specified by:: messageToolTip in class CloneableEditorSupport

Returns:: text to show to the user

messageLine

protected String messageLine(Line line)

Computes display name for a line based on the name of the associated DataObject and the line number.

Overrides:: messageLine in class CloneableEditorSupport

Parameters:: line - the line object to compute display name for
Returns:: display name for the line like "MyFile.java:243"
Since:: 4.3

initializeCloneableEditor

protected void initializeCloneableEditor(CloneableEditor editor)

Annotates the editor with icon from the data object and also sets appropriate selected node. But only in the case the data object is valid. This implementation also listen to display name and icon chamges of the node and keeps editor top component up-to-date. If you override this method and not call super, please note that you will have to keep things synchronized yourself.

Overrides:: initializeCloneableEditor in class CloneableEditorSupport

Parameters:: editor - the editor that has been created and should be annotated

notifyClosed

protected void notifyClosed()

Called when closed all components. Overrides superclass method, also unregisters listening on node delegate.

Overrides:: notifyClosed in class CloneableEditorSupport

createStyledDocument

protected StyledDocument createStyledDocument(EditorKit kit)

Let's the super method create the document and also annotates it with Title and StreamDescription properities.

Overrides:: createStyledDocument in class CloneableEditorSupport

Parameters:: kit - kit to user to create the document
Returns:: the document annotated by the properties

canClose

protected boolean canClose()

Checks whether is possible to close support components. Overrides superclass method, adds checking for read-only property of saving file and warns user in that case.

Overrides:: canClose in class CloneableEditorSupport

saveDocument

public void saveDocument()
                  throws IOException

Saves document. Overrides superclass method, adds checking for read-only property of saving file and warns user in that case.

Overrides:: saveDocument in class CloneableEditorSupport

Throws:: IOException

findDataObject
