This project shows how to override NSDocument class so that a document is a package : redefine -fileWrapperOfType:error: and -readFromFileWrapper:ofType:error: methods.

The documents by the application defined by this project consists of two texts; the document package contains a firstText directory, that includes the TXT.rtfd file, and the secondText file :

The document user interface uses two text views for handling the two texts.

I had of lot of difficulties in using -setRuleThickness: method of the NSRulerView class (Mac OS 4.X). At last, I discovered the ruler is not displayed correctly if the float argument has not an integer value. Si I built a small application that hilites this feature (bug ?).

This is an window capture.
