No, I believe what you're referring to is a template, and though such
a critter would surely be nice, they don't exist for Director (not
yet, not as far as I know).
What I mean by standard components is any regular button, menu or
control that appears in most programs, including the control items
that appear in many of Director's own windows. The closest approach
you can make to those yourself is with the items in the Tool Palette
and, while they surely are useful, they don't have a standard system
look and feel any more. (Back when Director was Mac-only, up to the
early 90s, those were standard looking components; they are not any
more.)
The OSC Xtra will give you those standard looking components again.
Plus they give you things that are otherwise rather difficult to
program via Lingo alone, such as popup menus and sliders.

I use it in everything. Absolutely everything. I use it more often
than I do FileXtra3 or BuddyAPI, which are also spectacularly useful
Xtras.

Yes. Then click the sprite and, in the PI behavior tab, select New
Behavior from the popup. What I sent along before should be OK to
copy and paste into the behavior's window. Then close the window and
click the gear icon in the PI (or set the properties directly through
the PI interface).

No, you'd remove the mouseDown handler from the behavior and put the
above in its place. It would be in the same behavior.

That's the idea, yes.

Yes, in theory anyway. ;)

Well, whichever sprite held the QT movie or sound file, yes. In order
for that to work you would have to do a couple things. First you'd
change the getPropertyDescriptionList exactly as you suggested; but
you'd also change the AdjustVolume() handler a little:
on AdjustVolume me
if pyMyDirection = #down then
sprite(pnMySoundChannel).member.volume = \
sprite(pnMySoundChannel).member.volume - 1
else
sprite(pnMySoundChannel).member.volume = \
sprite(pnMySoundChannel).member.volume + 1
end if
END AdjustVolume
This is because for QuickTime you adjust the volume of the *member*
in the Cast, rather than a sound channel in the score. The above
changes would do so by getting the Cast member associated with the
sprite you had chosen to be affected by the volume button behavior,
and then changing that Cast member's volume. Note this would not be a
permanent change; the next time someone ran your movie the QuickTime
sounds wouold be back to their original levels.
Apart from that it should work more or less as expected. ;)
