There can be situations, however, where none of our subpanes want to be
the target; a silly impasse. Our BeTarget then mimics the behaviour of
LTabGroup::BeTarget, but is prepared to accept the focus itself if necessary.
An added wrinkle comes from the inability of certain of our subpanes
(CPluginView) to correctly preflight whether they will be able to accept
the target (in ProcessCommand). When this happens, CPluginView tells its
supercommander (us) to be the target and a stack explosion results.
Thus the member variable, mTargeting, which detects recursive calls*/
/* Later note: BeTarget was gutted so that CHTMLView _could_ take the focus.
This solves problems that happen with simultaneous text selection in the
CHTMLView body and in a form edit field. If you wish to reinstate BeTarget(),
you must declare a private class boolean called mTargeting, and initialize
it to false in the constructor.
