Note: This function is meant to directly set the widget an accessible user is focused on, bypassing all of the focus change accessible events. This should only be used byFGenericAccessibleMessageHandlerand its subclasses to update the the accessible focus for an accessible user. Most of the time, you want to useIAccessibleWidget::SetUserFocusto request an accessible widget be focused on by a user. It raises the appropriate accessible events so listeners for accessible events can do the appropriate event handling for the focus change event.
