Examples of org.eclipse.jface.text.IWidgetTokenOwnerExtension.requestWidgetToken()

org.eclipse.jface.text.IWidgetTokenOwnerExtension.requestWidgetToken()

Requests the widget token from this token owner. Returns true if the token has been acquired or is already owned by the requester. This method is non-blocking.

priority is forwarded to any existing token keeper to give it an estimate on whether the request has higher priority than the current keeper's. There is, however, no guarantee that another keeper will release the token even if it has a high priority.

@param requester the token requester @param priority the priority of the request @return true if requester acquires the token,false otherwise
