NAME

6       wxScrollEvent - Functions for wxScrollEvent class
7

DESCRIPTION

9       A  scroll  event  holds  information about events sent from stand-alone
10       scrollbars (see wxScrollBar) and sliders (see wxSlider).
11
12       Note that scrolled windows send the wxScrollWinEvent which does not de‐
13       rive  from  wxCommandEvent,  but  from wxEvent directly - don't confuse
14       these two kinds of events and use the event table macros mentioned  be‐
15       low only for the scrollbar-like controls.
16
17       The difference between EVT_SCROLL_THUMBRELEASE and EVT_SCROLL_CHANGED
18
19       The  EVT_SCROLL_THUMBRELEASE  event is only emitted when actually drag‐
20       ging the thumb using the mouse and releasing it (This  EVT_SCROLL_THUM‐
21       BRELEASE event is also followed by an EVT_SCROLL_CHANGED event).
22
23       The  EVT_SCROLL_CHANGED  event  also  occurs when using the keyboard to
24       change the thumb position, and when clicking next to the thumb (In  all
25       these cases the EVT_SCROLL_THUMBRELEASE event does not happen).
26
27       In  short,  the  EVT_SCROLL_CHANGED  event is triggered when scrolling/
28       moving has finished independently of the way it had started. Please see
29       the  page_samples_widgets ("Slider" page) to see the difference between
30       EVT_SCROLL_THUMBRELEASE and EVT_SCROLL_CHANGED in action.
31
32       Remark: Note that unless specifying a scroll  control  identifier,  you
33       will  need  to  test  for  scrollbar orientation with getOrientation/1,
34       since horizontal and vertical scroll events  are  processed  using  the
35       same event handler.
