\section{\class{wxScrollEvent}}\label{wxscrollevent}

A scroll event holds information about events sent from stand-alone
\helpref{scrollbars}{wxscrollbar} and \helpref{sliders}{wxslider}. Note that
starting from wxWidgets 2.1, scrolled windows send the 
\helpref{wxScrollWinEvent}{wxscrollwinevent} which does not derive from
wxCommandEvent, but from wxEvent directly - don't confuse these two kinds of
events and use the event table macros mentioned below only for the
scrollbar-like controls.

\wxheading{Derived from}

\helpref{wxCommandEvent}{wxcommandevent}\\
\helpref{wxEvent}{wxevent}\\
\helpref{wxObject}{wxobject}

\wxheading{Include files}

<wx/event.h>

\input scrolevt.inc

\wxheading{Remarks}

Note that unless specifying a scroll control identifier, you will need to test for scrollbar
orientation with \helpref{wxScrollEvent::GetOrientation}{wxscrolleventgetorientation}, since
horizontal and vertical scroll events are processed using the same event handler.
