NSOpenPanel does not support filtering by UTI, but Navigation Services
does, and you can use it from a Cocoa app. See
NavDialogSetFilterTypeIdentifiers().
Thanks Sean - this appears to be exactly what I need. Unfortunately I have
two followup questions:
1) I can't seem to find NavDialogSetFilterTypeIdentifiers anywhere in the
Developer Documentation that got installed along with Xcode. Should I be
able to find it, or do I need to install extra documentation? (and yes, I
realize that the docs are available online, I just wondered why I can't seem
to find it locally).
2) I am a new to Apple development in general so I am not sure how I go
about calling, what appears to be a Carbon API from a Cocoa app. Do I need
to write the code that uses Nav Services in C or C++, instead of Obj-C?
Thanks,
BT
