2005-02-05 15:42 Gregory John Casamento <greg_casamento@yahoo.com>
* Headers/AppKit/NSDataLinkManager.h: Moved NSDataLinkManager delegate
methods to an informal protocol NSDataLinkManagerDelegate.
* Source/Functions.m: Implemented NSFrameLinkRect() to draw the frames
around source and destination links.
* Source/NSBundleAdditions.m: Modified -description method in
NSNibConnector to display the source, destination and label for the
connection. This makes it easier to debug.
* Source/NSDataLink.m: Implemented a few private methods.
* Source/NSDataLinkManager.m: Implemented -breakAllLinks.
