Split screen output for Presentations

[Sivakatirswami]

Tom, Dan:

Yes, of course one can set this all up manually. Keynote just seems to 
use apple internal ability to know all this stuff, which Revolution may 
not be able to access.

I work all day with my 17" G4 powerbook plugged into a 21" cinema 
display, with the external Cinema display monitor set to be the main 
monitor.

So, presumably if the presentor knows his variables ahead of time you 
can just write the scripts to drive the windows into the correct rects.

e.g. right now on my cinema display an open stack can be set to the 
screenloc and obviously, centers itself... If I open another stack at:

-1430,63,-443,604

it will appear on the on-board monitor of the powerbook itself, which 
is set to be the second monitor and arranged in the display panel of 
sys prefs to be on the left of external monitor.

Of course, this is all very doable by hand, but, as we say in Hawaii 
very "hokey!" i.e. a fiddle-dee-dee work around.  What one wants 
(obviously) is for Rev to be able to read all this these system 
parameters-variables, screen positions-rects in advance of the stack 
opening.


the screenrect gets you monitor 1... so a bit of math could get you the 
center of the project screen which should default to monitor two on the 
right... .. e.g. the horizontal center of monitor 2 for the projector  
800X600 would should be (item 3 of the screenrect+400)...

So, yes, doable, but "hokey"
