This is one step in the right direction. One. At least, insofar as
"we heard a very common request and, in the interests of
consistency and promoting good-looking apps on our platform, we
will address it."
OK, source lists were a fairly weak example. I guess what I meant
was -- in API terms -- source lists are "just" a stylistic variant,
whereas in fact they likely have behavioral differences too, in a
lot of scenarios. But there are no source list APIs, just indirect
sort-of customizations (like outlineView:isGroupItem:).
I like the source list example, having tried to use it with a subclass
of NSTextFieldCell. NSTableView evidently uses SPI to get the proper
bold and shadow attributes on the text; even with the new background
style API, you still can't make it draw text correctly with a subclass
[1].
-- Cells. Using cells to encapsulate drawing and interaction is fine
as an implementation detail, but exposing cells as a technique of
class customization is a real PITA. Cell programming, beyond the
simplest of overrides, is no fun at all (cells are on my short list
of cliff-ready experiments too), and there just isn't a wide enough
range of standard cells to meet the demand for customizations.
Yes! I loathe working with NSCell. If you want variable height rows
and an ImageAndTextCell, you have to subclass NSTextFieldCell to make
it draw vertically centered...and then fix the same problem for
editing. And fix your expansion cell rects. And the focus ring. And
probably a few other things that I'm too lazy to look up right now :).
Unfortunately, trying to figure out which NSCell methods to override
is almost impossible, since so many of them seem redundant (how many
people understand how cellSize, cellSizeForBounds, imageRectForBounds,
titleRectForBounds, and drawingRectForBounds are related? or calcSize
and calcDrawInfo:?). For additional confusion, lots of NSImageCell
and NSTextFieldCell-specific methods are in NSCell...but which ones?
I don't think documentation can even help at this point; I just keep
hoping NSCell will be pushed over the cliff and replaced by something
"very simple and light weight" [2].
