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.
| EVT_SCROLLWIN(func) | Process all scroll events. |
| EVT_SCROLLWIN_TOP(func) | Process wxEVT_SCROLLWIN_TOP scroll-to-top events. |
| EVT_SCROLLWIN_BOTTOM(func) | Process wxEVT_SCROLLWIN_TOP scroll-to-bottom events. |
| EVT_SCROLLWIN_LINEUP(func) | Process wxEVT_SCROLLWIN_LINEUP line up events. |
| EVT_SCROLLWIN_LINEDOWN(func) | Process wxEVT_SCROLLWIN_LINEDOWN line down events. |
| EVT_SCROLLWIN_PAGEUP(func) | Process wxEVT_SCROLLWIN_PAGEUP page up events. |
| EVT_SCROLLWIN_PAGEDOWN(func) | Process wxEVT_SCROLLWIN_PAGEDOWN page down events. |
| EVT_SCROLLWIN_THUMBTRACK(func) | Process wxEVT_SCROLLWIN_THUMBTRACK thumbtrack events (frequent events sent as the user drags the thumbtrack). |
| EVT_SCROLLWIN_THUMBRELEASE(func) | Process wxEVT_SCROLLWIN_THUMBRELEASE thumb release events. |

wxScrollWinEvent(WXTYPE commandType = 0, int id = 0, int pos = 0, int orientation = 0)
Constructor.
int GetOrientation() const
Returns wxHORIZONTAL or wxVERTICAL, depending on the orientation of the scrollbar.
int GetPosition() const
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.
