// in previous versions of wxWidgets the event types used to be constants
// which created difficulties with custom/user event types definition
//
// starting from wxWidgets 2.4 the event types are now dynamically assigned
// using wxNewEventType() which solves this problem, however at price of
// several incompatibilities:
//
//  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
//     with all versions of wxWidgets
//
//  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
// to get 100% old behaviour, however you won't be able to use the libraries
// using the new dynamic event type allocation in such case, so avoid it if
// possible.
