\section{\class{wxMouseEvent}}\label{wxmouseevent}
-This event class contains information about mouse events.
-See \helpref{wxWindow::OnMouseEvent}{wxwindowonmouseevent}.
+This event class contains information about the events generated by the mouse:
+they include mouse buttons press and release events and mouse move events.
-{\bf NB: } Note that under Windows mouse enter and leave events are not natively supported
+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.
+
+{\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
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 formet returns {\tt TRUE}
+{\bf NB:} Note the difference between methods like
+\helpref{LeftDown}{wxmouseeventleftdown} and
+\helpref{LeftIsDown}{wxmouseeventleftisdown}: the format 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{LeftDown}{wxmouseeventleftdown} returns {\tt TRUE},
\helpref{LeftIsDown}{wxmouseeventleftisdown} will also return {\tt TRUE} in
wxWindows whatever the underlying GUI behaviour is (which is
platform-dependent). The same applies, of course, to other mouse buttons as
values of {\it button} are 1, 2 or 3 for left, middle and right
buttons respectively.
-Not all mice have middle buttons so a portable application should avoid
-this one.

+\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.
