--> It's done automatically. * About the generic toolbar (File|Open, File|Save, etc): This toolbar contains XXE *parts*. A part may be *editing-context* *sensitive* or not. A part which is *not* editing-context sensitive updates its state when you switch from one document view to another (e.g. from foo.xml to bar.xml or from the styled view to the tree view). A part which is editing-context sensitive updates its state when you change the implicit or explicit selection or when the caret moves from one node to another. More info about parts in: XMLmind XML Editor - Customizing the User Interface, http://www.xmlmind.com/xmleditor/_distrib/doc/configure/index.html and in: XMLmind XML Editor - Developer's Guide, Extending the GUI of XMLmind XML Editor, http://www.xmlmind.com/xmleditor/_distrib/doc/dev/gui.html * About the toolbar which is specific to a document type (DocBook, XHTML, etc): The buttons contained in this toolbar update their states when the editing context changes. --> You can simulate an editing context change in Java by using: DocumentView.notifyContextChangeListeners() -- http://www.xmlmind.com/xmleditor/_distrib/doc/api/com/xmlmind/xmledit/view/DocumentView.html#notifyContextChangeListeners() This method is typically used when a command written in Java replaces the contents of the clipboard.
