6{\bf NB: } Note that under Windows mouse enter and leave events are not natively supported
7by the system but are generated by wxWindows itself. This has several
8drawbacks: the LEAVE\_WINDOW event might be received some time after the mouse
9left the window and the state variables for it may have changed during this
10time.

132\membersection{wxMouseEvent::Button}
133
134\func{bool}{Button}{\param{int}{ button}}

137values of {\it button} are 1, 2 or 3 for left, middle and right
138buttons respectively.
139
140Not all mice have middle buttons so a portable application should avoid
141this one.

156button down event. Otherwise the argument specifies which button-down event
157was generated (1, 2 or 3 for left, middle and right buttons respectively).
158

160
161\func{bool}{ButtonUp}{\param{int}{ but = -1}}
162
163If the argument is omitted, this returns TRUE if the event was a mouse
164button up event. Otherwise the argument specifies which button-up event
165was generated (1, 2 or 3 for left, middle and right buttons respectively).

VZ
250Please notice that it is {\bf not} the same as
251\helpref{LeftDown}{wxmouseeventleftdown} which returns TRUE if the left mouse
252button was just pressed. Rather, it describes the state of the mouse button
253before the event happened.
254
255This event is usually used in the mouse event handlers which process "move
256mouse" messages to determine whether the user is (still) dragging the mouse.
