Browser refresh button

[javier]

Hi there:

there's plenty of documentation regarding the handling of the
browser's back button with GWT's History tracking. I understand the
concept of mapping a String token to a specific application state.

Does GWT provide a mechanism to notify the application whenever the
user clicks the browser's refresh button? (ie the equivalent to
History.addValueChangeHandler() for the back button).

Is there a recommended strategy for handling the browser's refresh
button in the context of a GWT app? I'm curious to learn how are your
applications currently dealing with this.

Thanks in advance for any comments and suggestions.

Javier.

All you get to work with is the state held in the history token, stuff in cookies ... you can log the user back in to the application and use anything you have on the server, but basically it's a refresh and if the user wanted it in the state it was in before they hit F5, they wouldn't have hit F5.

You have to ask yourself what the user is trying to achieve by refreshing - do they really want all the form fields filled with what was there before, or are they trying to start again in the same condition but with a blank form?

My strategy is to get the user back to the state they were in when they first came to the page being shown if possible. (I use the word 'page' in a GWT sense)
