\wxheading{Event table macros}

To process a scroll window event, use these event handler macros to direct input to member
functions that take a wxScrollWinEvent argument. You can use the  EVT\_SCROLLWIN... macros
for intercepting scroll window events from the receiving window.

\membersection{wxScrollWinEvent::wxScrollWinEvent}\label{wxscrollwineventctor}

\func{}{wxScrollWinEvent}{\param{WXTYPE }{commandType = 0}, \param{int}{ pos = 0},
\rtfsp\param{int}{ orientation = 0}}

Constructor.

\membersection{wxScrollWinEvent::GetOrientation}\label{wxscrollwineventgetorientation}

\constfunc{int}{GetOrientation}{\void}

Returns wxHORIZONTAL or wxVERTICAL, depending on the orientation of the scrollbar.

\membersection{wxScrollWinEvent::GetPosition}\label{wxscrollwineventgetposition}

\constfunc{int}{GetPosition}{\void}

Returns the position of the scrollbar for the thumb track and release events.
Note that this field can't be used for the other events, you need to query
the window itself for the current position in that case.
