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

Returns true if the identified mouse button is changing state. Valid

\func{bool}{Entering}{\void}
\constfunc{int}{GetButton}{\void}
-Returns the mouse button which generated this event or $-1$ if no button is
-involved (for mouse move, enter or leave event, for example). The value $1$ is
-returned for the left button down, up and double click events, $2$ and $3$ for
-the same events for the middle and the right buttons respectively.
+Returns the mouse button which generated this event or {\tt wxMOUSE\_BTN\_NONE}
+if no button is involved (for mouse move, enter or leave event, for example).
+Otherwise {\tt wxMOUSE\_BTN\_LEFT} is returned for the left button down, up and

+for the same events for the middle and the right buttons respectively.

+Get wheel delta, normally $120$. This is the threshold for action to be
taken, and one such action (for example, scrolling one increment)
should occur for each delta.
Returns true if the middle mouse button changed to up.
-\membersection{wxMouseEvent::Moving}
+\membersection{wxMouseEvent::Moving}\label{wxmouseeventmoving}
\constfunc{bool}{Moving}{\void}
-Returns true if this was a motion event (no buttons depressed).
+Returns true if this was a motion event (whether some buttons are currently
+pressed or not, use \helpref{Dragging}{wxmouseeventdragging} if you need to
+distinguish between these situations).
