@PageTitle/HasDynamicTitle for application

[stefanuebe]

Currently @PageTitle and HasDynamicTitle are only interpreted when used in a routed component. That is useful for applications, where each view should show a separate title.

But there are other use cases where this behavior is not useful:

• Only one static title is needed. In that case setting the title for every view is overkill.
• Applications, that want to dynamically manage the title per route in a single place, for instance together with updating active menu buttons, etc.

(The second case can be achieved by using afterNavigation and Page.setTitle, but that approach has the disadvantage, that the page might be built already and the title is set with some lag, when the components take long to load - with using HasDynamicTitle it could be loaded prior to the page itself).

The request is to let those title configs also be usable on route layouts.

For the case, that a nested route layout or a route itself also defines a title, the most specific should always win (route > inner route layout > outer route layout).

How about writing the application logic for handling the title in your own interface that extends HasDynamicTitle, and then making all your own views implement that interface, optionally overriding things ?

I would consider that as a workaround - in the end its the same as having a String constant somewhere and let every view use that inside the @PageTitle.

It is surely possible to overcome the basic problem by either using your approach or the one with the constant String, but in the end it's unneeded dev overhead, especially for such a "simple" feature, that HTML knows for decades now.

(I personally do not consider this a very critical request but rather more a nice to have, since it appears to be a basic feature that I guess many devs would expect from a UI framework to have :) )

I came here looking for a way to inherit the page title from a parent layout. It seems setTitle(...) during afterNavigation no longer works (see #13871). @PageTitle on the AppShellConfigurator works, but that's not dynamic / localizable; letting it implement HasDynamicTitle doesn't seem to do anything.

As it seems HasDynamicTitle does not work for layouts neither?
