-//
-// a) event table macros declaration changed, it now uses wxEventTableEntry
-// ctor instead of initialisation from an agregate - the macro
-// DECLARE_EVENT_TABLE_ENTRY may be used to write code which can compile

-//
-// b) event types can't be used as switch() cases as they're not really
-// constant any more - there is no magic solution here, you just have to
-// change the switch()es to if()s
-//
-// if these are real problems for you, define WXWIN_COMPATIBILITY_EVENT_TYPES
-// as 1 to get 100% old behaviour, however you won't be able to use the
