I have a collection of objects which describe an image-name, its size and it's X/Y location. The collection is sorted by "layers", so I can composite the images in a sort of painter's algorithm. From this, I can determine the rectangle necessary to hold all of the images, so now what I want to do is: Create some sort of buffer to hol...
I have an NSTableView that has a very small fixed number of rows. When I create an NSTableView in Interface Builder, the NSTableView is contained within an NSScrollView. I have not found a way to make the table exist outside the context of a scroll view. Since the table only has a small number of rows, I don't want it to scroll. I wa...
I have a NSWindow that hosts a WebView that Ive hooked up to a script handler. Now, when the user clicks a button on a control on the WebView it calls a Objective C method on my object.

I suspect that the number of dividers in an NSSplitView is equal to [[MySplitViewObject subviews] count] -1 and that the index of any given divider in an NSSplitView is equal to the index of the subview to the left of or above the divider (depending on the NSSplitView's orientation). Is it, or is there some undocumented and exposed prop...

In Chapter 12 he wants me to create an about window using [BOOL] successful = [NSBundle loadNibNamed:@"About" owner:self]; which, by itself, works perfectly well. However, I am using the garbage collector and since I do not retain a pointer to t...
