You need to declare the types of extensions your app will look for in the
open panel -- like this:

    static const char *openTypes[] = {"ext1", "ext2", NULL};
        // do not include the ".", ie "wn", not ".wn"
    id openPanel = [OpenPanel new];
    static char dir[MAXPATHLEN+1];
    static char file[MAXPATHLEN+1]

    // decide what directory and file you want to default the open panel to
    if ([openPanel runModalForDirectory:dir file:file types:openTypes]) {
        //do your thing 
    } else {
        // can't do your thing because openPanel failed or was canceled
    }

Hope this helps.
