I figured out how to get the NSPathControl to "resize" after changing an NSPathComponentCell URL.
I realize that the description I gave is vague, so here is a better explanation..
I am changing the URL of a NSPathComponent in the middle of NSPathControl's overall URL.
By making the change, I was hoping that the imagery would adjust itself after I made the change.
This turned out to not be the case.
Here is what I discovered:
NSPathComponentCell contains its "fragment" of the path. If you have a path like:
/Users/myhome/Movies/Summer/MyMovie.mov
and you want to change "Summer" to "Winter", you would find the NSComponentCell and make the URL change.
(ie: /Users/myhome/Movies/Summer becomes /Users/myhome/Movies/Winter)
The problem is that NSPathControl still sees the original path with "Summer".
I found that I had to iterate through the rest of the NSPathComponentCells in NSPathControl, and update each of the subsequent NSComponentCell objects with the new URL fragments.
I then took the last URL fragment, and then updated NSPathControl with the newly changed URL.
That no only re-drew the artwork, but also correctly updated the URL path in NSPathControl.
A lot of work, but thats what it took.
