\wxheading{Event table macros}

To process a scroll event, use these event handler macros to direct input to member
functions that take a wxScrollEvent argument. You can use EVT\_COMMAND\_SCROLLWIN... macros
with window IDs for when intercepting scroll events from controls, or EVT\_SCROLLWIN... macros
without window IDs for intercepting scroll events from the receiving window.
