64 // in previous versions of wxWidgets the event types used to be constants
65 // which created difficulties with custom/user event types definition
66 //
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 // as 1 to get 100% old behaviour, however you won't be able to use the
82 // libraries using the new dynamic event type allocation in such case, so avoid
83 // it if possible.
