259 /*
1f2f0331
VZ
260 In wxFileSelector you can put, instead of a single wild_card,
261 pairs of strings separated by '|'.
262 The first string is a description, and the
263 second is the wild card. You can put any number of pairs.
2bda0e17 264
1f2f0331 265 eg. "description1 (*.ex1)|*.ex1|description2 (*.ex2)|*.ex2"
2bda0e17 266
1f2f0331

267 If you put a single wild card, it works as before the modification.
