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.
+{\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

\constfunc{int}{GetWheelRotation}{\void}
Get wheel rotation, positive or negative indicates direction of
-rotation. Current devices all send an event when rotation is equal to
-+/-WheelDelta, but this allows for finer resolution devices to be
-created in the future. Because of this you shouldn't assume that one
-event is equal to 1 line or whatever, but you should be able to either
-do partial line scrolling or wait until +/-WheelDelta rotation values
-have been accumulated before scrolling.

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.
+Please notice that it is \emph{not} the same as
+\helpref{LeftDown}{wxmouseeventleftdown} which returns \true if the event was
+generated by the left mouse button being pressed. Rather, it simply describes
+the state of the left mouse button at the time when the event was generated
+(so while it will be true for a left click event, it can also be true for
+a right click if it happened while the left mouse button was pressed).
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.
