\helpref{LeftIsDown}{wxmouseeventleftisdown} to test
whether the left mouse button is (still) depressed. Also, by convention, if

+\helpref{LeftDown}{wxmouseeventleftdown} returns {\tt TRUE},
\helpref{LeftIsDown}{wxmouseeventleftisdown} will also return {\tt TRUE} in
wxWindows whatever the underlying GUI behaviour is (which is
