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 $1$ for the left mouse button, $2$
for the middle one and $3$ 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.
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 wxWindows itself. This has several
