My NSDocument-based application is capable of reading and writing most common image formats (GIF, JPG, PNG, etc). I'm currently searching for a way to perform the following: upon saving (or creating) a file with my program, it should default to opening with my application. Not all files of that format, just the specific one I created.
Example: create a document with Word, modify and save it with OpenOffice. In the future, double-clicking the file will open it with OOo. Same goes for images (Preview versus Photoshop, etc). I'm sure it's a simple fix, but I just can't find it. Thanks in advance!
