I have a NSView subclass that displays a graphical representation of
my model.
The model is described by some numerical values, which are entered
into text fields.
As each text field is edited, the graphical representation should be
redrawn to reflect the new value.
What's the most recommended way to trigger a redraw -- in other
words, to cause setNeedsDisplay to be called -- whenever one of
these values changes?
In MVC style, you would have a controller that observes for value
changes and then calls the appropriate methods on the view. You could
add bindings support in your view, but you would still need a
controller and this approach might be more work than it is worth
(unless you want broader re-use).
