\constfunc{bool}{LeftDown}{\void}
Returns TRUE if the left mouse button is currently down, independent
of the current event type.
+Please notice that it is {\bf not} the same as
+\helpref{LeftDown}{wxmouseeventleftdown} which returns TRUE if the left mouse
+button was just pressed. Rather, it describes the state of the mouse button
+before the event happened.
+
+This event is usually used in the mouse event handlers which process "move
+mouse" messages to determine whether the user is (still) dragging the mouse.
