+This event class contains information about the events generated by the mouse:
+they include mouse buttons press and release events and mouse move events.
+
+All mouse events involving the buttons use {\tt wxMOUSE\_BTN\_LEFT} for the
+left mouse button, {\tt wxMOUSE\_BTN\_MIDDLE} for the middle one and
+{\tt wxMOUSE\_BTN\_RIGHT} for the right one. Note that not all mice have a
+middle button so a portable application should avoid relying on the events from
+it.
+
+{\bf NB:} Note that under Windows mouse enter and leave events are not natively supported
+by the system but are generated by wxWidgets itself. This has several
+drawbacks: the LEAVE\_WINDOW event might be received some time after the mouse
+left the window and the state variables for it may have changed during this
+time.
+
+{\bf NB:} Note the difference between methods like
+\helpref{LeftDown}{wxmouseeventleftdown} and
+\helpref{LeftIsDown}{wxmouseeventleftisdown}: the former returns {\tt true}
+when the event corresponds to the left mouse button click while the latter
+returns {\tt true} if the left mouse button is currently being pressed. For
+example, when the user is dragging the mouse you can use
+\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
+wxWidgets whatever the underlying GUI behaviour is (which is
+platform-dependent). The same applies, of course, to other mouse buttons as
+well.
