how to configure Application Title at runtime? [message #460036]

as we all know, the title is configured by using
IWorkbenchWindowConfigurer.setTitle(String title)

but at runtime, how shall we get IWorkbenchWindowConfigurer to reset the
title?

Thanks

I've used the following technique:

public static void changeAppTitle(String newTitle) {
Display display = Display.getDefault();
if (display != null) {
// Look at all the shells and pick the first one
// that is a workbench window.
Shell shells[] = display.getShells();
for (int i = 0; i < shells.length; i++) {
Object data = shells[i].getData();
// Check whether this shell points to the Application main window's
shell:
if (data instanceof IWorkbenchWindow) {
shells[i].setText(newTitle);
break;
}
}
}
}

I've used a different method, that I *think* is safer, but requires setting up a suitable
listener-mechanism to respond to whatever it is that you want to have determine the new title; in my
case, it's a preference. I do it all in the WorkbenchWindowAdvisor, note calls to setTitle() in two
places:

MyWorkbenchWindowAdvisor extends WorkbenchWindowAdvisor implements IPropertyChangeListener {
....
@Override
public void preWindowOpen() {
super.preWindowOpen();
_configurer = getWindowConfigurer();
<other code>
setTitle();
PreferencesImpl.store().addPropertyChangeListener(this);
}

public void propertyChange(final PropertyChangeEvent event) {
if (event.getProperty().equals(MY_PREFERENCE_KEY)) {
if (!event.getOldValue().equals(event.getNewValue())) {
setTitle();
}
}
}

protected void setTitle() {
final String title = computeNewTitleHoweverYouLike();
_configurer.setTitle(title);
}

protected IWorkbenchWindowConfigurer _configurer;
}

HTH,
Paul

Thanks a lot, I got the solution now:

I pass a WorkbenchWindow parameter into Action constructor when create
the instance in ActionBarAdvisor.

Then in the action, we can use window.getShell().setText()....
