Gregg was referring to the Drag Manager, originally
provided by the
Macintosh Drag and Drop system extension and later built
into the OS (in 7.5, I think).
The drag and drop stuff was included with System 7.1 but could
either be downloaded from Apple or copied from 7.1 to 7.0.x Same
thing with the clipping extension, thread manager and some other 7.1
features to enable some software that "requires" 7.1 to run on 7.0.x.
Assuming the application asks "Is the Thread Manager installed?"
rather than "Is this System 7.1 or later?". Otherwise it gets
tricky. :-)
IIRC it was Drag Manager that enabled moving windows partially
beyond the screen edges, without it windows are always fully within
the screen bondaries.
Enforcing the placement of windows (like many things in Mac OS) is up
to each application. The DragWindow() Toolbox call (part of the
Window Manager) has a bounds parameter to which screenBits.bounds is
typically passed, but that only constrains the point that was clicked,
not the entire window structure, so you can drag windows as far
offscreen as you can reach (except that the last six pixels or so
toward the edge are a drag-canceling dead zone in more recent versions
of classic Mac OS, but not Mac OS X).
The Drag Manager is an entirely different API, concerned with dragging
things between different applications. If you drag an item from the
Finder into another app, that's the Drag Manager at work.
