An example of one of these template classes is NSWindowTemplate.
Are you sure about this? I thought that NSWindowTemplate was only
used within IB, and that it actually instantiated an NSWindow and
wrote *that* into the .nib. IIRC, NSWindowTemplate provides the
IB-specific window behavior like accepting dragged objects from the
palettes and drawing the blue, dashed layout lines.
It's easy to check for yourself. Just load a Cocoa app into gdb,
set breakpoints at NSWindowTemplate's initWithCoder: and NSWindow's
initWithCoder: and initWithContentRect:styleMask:backing:defer:, and
run it. When the main window is loaded, execution should break first
at NSWindowTemplate's initWithCoder:, then at NSWindow's
initWithContentRect:styleMask:backing:defer:, but never at NSWindow's
initWithCoder:.
Let's see then... Doesn't that make [NSWindow initWithCoder:] a noOp?
If it's not called when taking a window out of a nib, then when would it
ever get used?
I guess somebody might do something pathological like pass a window
bycopy over a DO connection, but I've never seen it done..
