+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. And if the system supports more
+buttons, the \texttt{wxMOUSE\_BTN\_AUX1} and \texttt{wxMOUSE\_BTN\_AUX2} events
+can also be generated. Note that not all mice have even a middle button so a
+portable application should avoid relying on the events from it (but the right
+button click can be emulated using the left mouse button with the control key
+under Mac platforms with a single button mouse).
+
+For the \texttt{wxEVT\_ENTER\_WINDOW} and \texttt{wxEVT\_LEAVE\_WINDOW} events
+purposes, the mouse is considered to be inside the window if it is in the
+window client area and not inside one of its children. In other words, the
+parent window receives \texttt{wxEVT\_LEAVE\_WINDOW} event not only when the
+mouse leaves the window entirely but also when it enters one of its children.
+
+{\bf NB:} Note that under Windows CE 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.
