requestWidgetToken
boolean requestWidgetToken(
IWidgetTokenOwner owner,
int priority)
- The given widget token owner requests the widget token from
this token keeper. Returns
true if the token is released
by this token keeper. Note, the keeper must not call
releaseWidgetToken(IWidgetTokenKeeper) explicitly.
The general contract is that the receiver should release the token
if priority exceeds the receiver's priority.

-
Parameters:
-
owner - the token owner -
priority - the priority of the request
-
Returns:
-
true if token has been released false otherwise
setFocus
boolean setFocus(
IWidgetTokenOwner owner)
- Requests the receiver to give focus to its popup shell, hover, or similar. There is
no assumption made whether the receiver actually succeeded in taking the focus. The return
value gives a hint whether the receiver tried to take focus.
-
-
Parameters:
-
owner - the token owner
-
Returns:
-
true if the receiver tried to take focus, false if it did not.
