Having fixed my main-level XManager issues (thankfully fairly
trivial), I now find myself with another problem. Typically, I
recommend setting something like:
device,DECOMPOSED=0,TRUE=16,RETAIN=2
in your IDL startup file, where RETAIN=2 is good for most Linux
machines (whose window managers don't provide decent backing store),
DECOMPOSED=0 is immortalized on David's site, and TRUE=16 is just for
good measure, for those X servers which *claim* to offer DirectColor
but don't really (sadly, not few in the Linux world). However, I
leave it up to the end user to find some combination of device
incantations which work for them.
That's fine for interactive usage, but with a runtime/VM application,
the startup file is never consulted, so you need to perform these
device incantations yourself in the code. Has anyone solved this
problem in a platform-independent way? Would something like:
device,DECOMPOSED=0,RETAIN=2
always be safe, even for older 8-bit PSEUDOCOLOR machines? Or is
there some method of interrogating DEVICE for info before making a
final decision on RETAIN and color-model settings? What guidance from
the IDL color gurus?
Thanks,
JD
