This is topic that I have grown to be very interested in in recent times.

How do most developers go about tracking their currentDocument in multidoc apps.

I am currently using draw's approach using mainWindow. (Note to scott, Im interested in seeing what people have to say about this)  This assumes that you
have a window.  I have the following problem with an app Im writing using this
approach.

I have a subview of my document window's contentView  which condionally does an
NXHightlight rect in its drawSelf. The drawSelf is executed first when I send
my window makeKeyAndOrderFront.  The thing it highlights is the currentDocument's currently highLightedroom.

Code follows.

- drawSelf:(NXRect *)rects :(int)count
{

    Room *highlightedRoom;
        
  /* erase update rect since the nximage might be smaller than our bounds */

    PSsetgray(NX_WHITE);
    NXRectFill(&rects[0]);
            
    [image composite:NX_COPY
              fromRect:&rects[0]
              toPoint:&rects[0].origin];
                
    highlightedRoom = [[NXApp currentDocument] currentHighlightedRoom];
    if (highlightedRoom) {
        NXRect intersectRect;
        NXRect *intersects;
                                
        [highlightedRoom scaledRoomRect:&intersectRect];
        intersects = NXIntersectionRect(&rects[0],&intersectRect);
        if (intersects) {
            NXHighlightRect(&intersectRect);
        }
    }
       
    return self;
}

OK, this is here so I can preserve the highlighting when I scroll the view aroun
d otherwise it would get completely redrawn and overwrite my highlighting.  I as
sume you follow this.

Now, the problem occurs when I create a new document using new: since when its t
ime to send the window makeKeyAndOrderFront it will send my view a display the p
roblem is that the currentDocument at this time is still the old one.  Thus I will get the same highlighted area from my previous document highlighted in my new one.

Hope this is clear.  You see I need my window to appear in NXApps windowList bef
ore it sends a drawSelf. ???

What are the common uses of windowDidResignKey and windowDidResignMain when applied to apps that have global inspectors.
