Need Help creating Icon overlays for my SVN Client
Hi I am currently writing an cross platform SVN client. I have icon overlay working in windows and linux. This is a small image that sits on top of the normal icon in finder and represents the current state of the file, e.i out of sync, up to date, un-versioned. But am really struggling trying to get it to work in OSX. At this point I only want it to work in snow leopard. This is where I have got to so far.
I managed to create a QL plugin that worked. The only issue with QL plugins is that you have to specify what file types your plugin works for, (my sample worked for gifs). Unfortunately I don't know that as it needs to work for every file and folder on the system that contains a subfolder called .svn. So with a week of reading I have come to the decision that the only real way around this is to override the QLThumbnailImageCreate function that finder calls and replace it with my own if I find a .svn or call the original if not. However if this is the only route I have not been able to get any code to work that will replace the function with my own.
If any one can show me an example of switching that function, or has an alternative solution. Or knows the LSItemContentTypes type that means my plugin will fire for every single file, then I would be very happy. I've spent no more than 2 days getting this to work on windows and linux, but I've spent soooo many hours on OSX. Any help would be great.
