Code Block

language	java

/**

 * @return the currently displayed text
 */
public String getText() {
    return getDocumentProvider().getDocument(getEditorInput()).get();
}
/** The listener that is currently registered for this editor. */
private IDocumentListener registeredListener;
/**
 * Registers the given runnable as listener for changes to the text
 * of this editor.
 * @param runnable a runnable to register as text listener
 */
public void registerTextListener(final Runnable runnable) {
    registeredListener = new IDocumentListener() {
        public void documentAboutToBeChanged(DocumentEvent event) {}
        public void documentChanged(DocumentEvent event) {
            runnable.run();
        }
    };
    getDocumentProvider().getDocument(getEditorInput())
            .addDocumentListener(registeredListener);
}
/**
 * Removes the last registered text listener.
 */
public void disposeTextListener() {
    if (registeredListener != null) {
        if (getDocumentProvider() != null) {
            getDocumentProvider().getDocument(getEditorInput())
                    .removeDocumentListener(registeredListener);
        }
        registeredListener = null;
    }
}

Add the following code to TapeViewPart:

Code Block

language	java

/** The editor part that is currently set as input for the viewer. */
private SimpleEditorPart currentInput;
/**
 * Sets the displayed text of the given editor part as input of the
 * viewer, if the editor part is a SimpleEditorPart.
 * @param part workbench part to set as input
 */
private void setInput(final IWorkbenchPart part) {
    if (part instanceof SimpleEditorPart && part != currentInput) {
        if (currentInput != null) {
            currentInput.disposeTextListener();
        }
        currentInput = (SimpleEditorPart) part;
        Runnable runnable = new Runnable() {
            public void run() {
                tape.setText(new StringBuffer(currentInput.getText()));
                tableViewer.refresh();
            }
        };
        runnable.run();
        currentInput.registerTextListener(runnable);
    }
}

Add the following code to createPartControl():

Code Block

language	java

IWorkbenchWindow workbenchWindow = getSite().getWorkbenchWindow();
IWorkbenchPage activePage = workbenchWindow.getActivePage();
if (activePage != null) {
    setInput(activePage.getActivePart());
}
workbenchWindow.getPartService().addPartListener(new IPartListener() {
        public void partActivated(final IWorkbenchPart part) {
            setInput(part);
        }
        public void partDeactivated(final IWorkbenchPart part) {}
        public void partBroughtToTop(final IWorkbenchPart part) {}
        public void partClosed(final IWorkbenchPart part) {}
        public void partOpened(final IWorkbenchPart part) {}
});
