Hi all -
I'm working on an app that has the concept of allowing the user to create
templates of things which are then instanced into a document. Central to this
is the idea that the user can create a template, then select it as part of
another template or an instance. The relationship between t

How do I use cocoas garbage collector in c++? It seems to be implemented in c++
with libauto:

But I cant seem to find that much documentation on it.

Use LSCopyAllRoleHandlersForContentType to get a list of bundle identifiers.
The bundle identifiers you can convert into full paths using NSWorkspace, which
also has a method to retrieve an icon that for a file at a full path (which in
the case of an app, will return an app icon).
Cheers,

The API:s to use for things like this would be NSWorkspace, and Launch
Services. In that order of preference.

How can I get a list of bundle identifiers (or paths to an app) for all the
apps that can open a file of a given type (eg pdf, mp3 etc)
Then, How can I get an icon for these apps?

Hi Ken,
Thanks, that works, problem solved. FSGetCatalogInfo (&ref,
kFSCatInfoCreateDate.. is a better option to obtain creation date when you need
