Hi,
you could let your DocumentController decide if an "empty" Document
already exists and then send the document the message to open the
double-clicked file.
At the moment I am not sure if "simple" subclasses of NSDocument and
NSDocumentController can already do this without much subclassing
code. You will need at least a method that returns YES/NO in your
NSDocument subclass dependend on the contents of your actual instance
of your open document.
I recommend reading through the Documentation of both classes in the
Cocoa library. If oyu need further pointers please call back either
offlist or onlist.

How do I get a document to open in a specified window?
Apple's TextEdit.app does exactly this.
When you open TextEdit, there is an empty window.
If you open a .txt document from the finder, that window gets used
as the file editor!
So TextEdit was able to use an existing specified window, instead
of opening a new one.
I'd like to be able to do the same. Any ideas anyone?
