I have an IDL application I've been running on The Operating System
Formerly Known As OS X (now macOS) for years that takes a time series of 2048 x
2048 pixel images, scales them logarithmically (lots of dynamic range in the
system), converts that 3-D array to a of byte for 8-bit display (as I said,
it's old) as a movie.
IDL has an XINTERANIMATE routine that uses the backing store to display the
resulting movie in an X11 widget with speed, gamma, and other controls, and the
code has run successfully most recently under IDL 8.4, macOS 10.2, and Xquartz
2.7.9.
I updated to 2.7.10 today, only to find the application crashes with:
Error: attempt to add non-widget child "dsm" to parent "idl" which
supports only widgets
in one of the Harris/ExelisVis-supplied library routines called by
XINTERANIMATE (CW_ANIMATE, which does a bunch of widget-related things).
I don't include the IDL CW_ANIMATE code here, because (1) Harris doesn't
release the internal code for XINTERANIMATE and (2) the library routine is
under their copyright. But has anyone else seen any “dsm” (whatever that
is)-related issues related to the transition from 2.7.9 to 2.7.10?
By the way, I would have submitted this to Bugzilla, but there's no option
in the version menu yet for 2.7.10.
Thanks for any clues,
Joe Gurman
