All Known Implementing Classes:
public interface IWidgetTokenKeeper
A widget token keeper may require a widget token from an
IWidgetTokenOwner and release the token to the
owner after usage. A widget token owner may request the token from the token
keeper. The keeper may deny the return of the token.
The widget token owner and keeper interplay is used by a text viewer in
order to manage the appearance and disappearance of addition, on-top popup
windows such as text hovers, content assist, etc.
In order to provide backward compatibility for clients of
IWidgetTokeKeeper, extension interfaces are used as a means
of evolution. The following extension interfaces exist:
IWidgetTokenKeeperExtension since version
3.0 introducing priorities when requesting a widget token and thus replacing
the non-prioritized scheme. It also allows a client to force a widget token
keeper to accept focus.
- The given widget token owner requests the widget token from this token
true if the token is released by this
token keeper. Note, the keeper must not call
owner - the token owner
true if token has been released
