Class History

java.lang.Object

com.google.gwt.user.client.History

public static class History
extends Object

This class allows you to interact with the browser's history stack. Each "item" on the stack is represented by a single string, referred to as a "token". You can create new history items (which have a token associated with them when they are created), and you can programmatically force the current history to move back or forward.

In order to receive notification of user-directed changes to the current history item, implement the ValueChangeHandler interface and attach it via #addValueChangeHandler(ValueChangeHandler).

Example

URL Encoding

Any valid characters may be used in the history token and will survive round-trips through #newItem(String) to #getToken()/ ValueChangeHandler#onValueChange(com.google.gwt.event.logical.shared.ValueChangeEvent) , but most will be encoded in the user-visible URL. The following US-ASCII characters are not encoded on any currently supported browser (but may be in the future due to future browser changes):

• a-z
• A-Z
• 0-9
• ;,/?:@&=+$-_.!~*()
