 \section{\class{wxMouseEvent}}\label{wxmouseevent}
 
-This event class contains information about mouse events, particularly
-events received by canvases. 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.
+
+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.
+
+{\bf NB:} Note the difference between methods like
+\helpref{LeftDown}{wxmouseeventleftdown} and
+\helpref{LeftIsDown}{wxmouseeventleftisdown}: the former 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{LeftIsDown}{wxmouseeventleftisdown} will also return {\tt true} in
+wxWidgets whatever the underlying GUI behaviour is (which is
+platform-dependent). The same applies, of course, to other mouse buttons as
+well.

-Sets *x and *y to the position at which the event occurred. If the
-window is a canvas, the position is converted to logical units
-(according to the current mapping mode) with scrolling taken into
-account. To get back to device units (for example to calculate where on the
-screen to place a dialog box associated with a canvas mouse event), use
-\rtfsp{\bf wxDC::LogicalToDeviceX} and {\bf wxDC::LogicalToDeviceY}.
 
-For example, the following code calculates screen pixel coordinates
-from the frame position, canvas view start (assuming the canvas is the only
-subwindow on the frame and therefore at the top left of it), and the
-logical event position. A menu is popped up at the position where the
-mouse click occurred. (Note that the application should also check that
-the dialog box will be visible on the screen, since the click could have
-occurred near the screen edge!)
