Thanks for the link Ted but I'm afraid I didn't glean anything useful
there...
RG 21.12 runs ok on this system (lying around in /usr/local/bin)
Rosegarden version: 21.12 ("Cloud Nine")
Build key: ac38e2622f (21.06-24-gb9da2db9d)
Built against Qt version: 5.15.2
Current version info is:
Rosegarden version: 24.12 ("Incredible")
Build key: 442818511e (24.06-1-gf91b7e227)
Built against Qt version: 5.15.13
How would I be "requesting the gtk widgets"? I am not aware of having,
or how I would have, done so...
I assume that my RG preferences would be applied the same to both of the
above versions?
TIA
Chuck.

Just some limited searching seems to indicate that the "gtk" widget
style was dropped around Qt 5.7 or so. Maybe you're running a newer
version of Qt and you are requesting the gtk widgets?

See post #36.
All the trails are from 2016/2017, though. Not sure they are
relevant today.

Rosegarden won't run at the moment.
The problem seems to be something to do with "GtkWidget" (see below).
24.06 built fine from git source.
I have recently upgraded to fedora 39 and this is probably the first
time I have tried to
run RG since. Same result on a similar/identical system.
gtk3-3.24.41-1.fc39.x86_64
gtk4-4.12.5-1.fc39.x86_64
