230 /*
1f2f0331
VZ
231 In wxFileSelector you can put, instead of a single wild_card,
232 pairs of strings separated by '|'.
233 The first string is a description, and the
234 second is the wild card. You can put any number of pairs.
2bda0e17 235
1f2f0331 236 eg. "description1 (*.ex1)|*.ex1|description2 (*.ex2)|*.ex2"
2bda0e17 237
1f2f0331
VZ
238 If you put a single wild card, it works as before the modification.
