  53 // in previous versions of wxWidgets the event types used to be constants
  54 // which created difficulties with custom/user event types definition
  55 //
  56 // starting from wxWidgets 2.4 the event types are now dynamically assigned
  57 // using wxNewEventType() which solves this problem, however at price of
  58 // several incompatibilities:
  59 //
  60 //  a) event table macros declaration changed, it now uses wxEventTableEntry
  61 //     ctor instead of initialisation from an agregate - the macro
  62 //     DECLARE_EVENT_TABLE_ENTRY may be used to write code which can compile
  63 //     with all versions of wxWidgets
  64 //
  65 //  b) event types can't be used as switch() cases as they're not really
  66 //     constant any more - there is no magic solution here, you just have to
  67 //     change the switch()es to if()s
  68 //
  69 // if these are real problems for you, define WXWIN_COMPATIBILITY_EVENT_TYPES
  70 // as 1 to get 100% old behaviour, however you won't be able to use the
  71 // libraries using the new dynamic event type allocation in such case, so avoid
  72 // it if possible.
