  67 // starting from wxWidgets 2.4 the event types are now dynamically assigned
  68 // using wxNewEventType() which solves this problem, however at price of
  69 // several incompatibilities:
  70 //
  71 //  a) event table macros declaration changed, it now uses wxEventTableEntry
  72 //     ctor instead of initialisation from an agregate - the macro
  73 //     DECLARE_EVENT_TABLE_ENTRY may be used to write code which can compile
  74 //     with all versions of wxWidgets
  75 //
  76 //  b) event types can't be used as switch() cases as they're not really
  77 //     constant any more - there is no magic solution here, you just have to
  78 //     change the switch()es to if()s
  79 //
  80 // if these are real problems for you, define WXWIN_COMPATIBILITY_EVENT_TYPES
  81 // to get 100% old behaviour, however you won't be able to use the libraries
  82 // using the new dynamic event type allocation in such case, so avoid it if
