[comp.sys.apple] Switching between screen modes

TMPLee@DOCKMASTER.NCSC.MIL (02/05/90)

What is the right and/or easiest way to switch between screen modes
using the toolbox etc?  I'm writing a little something where I want to
alternate between 640 mode for dialogues and 320 mode for display of
full-screen color graphics.  The only obvious thing I can find where one
tells all the tools what mode you're in is in QD startup -- does that
mean in order to switch modes one has to shut down Quick Draw and then
start it up again in the new mode?  (I know there are SCB bytes buried
in GrafPorts and other places, but fiddling with those didn't seem to
work; neither does the refresh window or some such command.)  As it is,
I ran into a problem in that the toolbox (menu manager I think, sinc eit
only shows up on the lines where the menu was) puts some of the lines in
fill mode when I want them in non-fill so I can use all 16 colors.
(That was easy to fix by resetting all the SCB's to 0).
