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.
