nope.

qtractor does the lv2 external-ui extension only. this is the only lv2 ui
extension that is framework/toolkit agnostic.

it is my stance that all lv2 plugin authors should make their plugins
independent of the host implementation gui toolkit. the lv2 external-ui
extension delivers this independence. you can either do in-process or
out-of-process (like dssi), and most importantly you can do it on whatever
toolkit you believe sucks less.

nb. lv2ui:gtk plugins will only show on gtk hosts. lv2ui:qt plugins will
only show on qt hosts, if there will ever be one that supports it
specifically. qtractor won't be one of them, sorry.

fwiw, use the lv2 external-ui extension.

stay away from all gtk (qt) lock-in (lock-out) epidemics ;)

cheers
