In compat code of InstrumentTrack::loadTrackSpecificSettings() also
check for nodeName being equal to ControllerConnection::classNodeName().
This avoids trying to load the non-existing instrument "connection".
In master branch this has been fixed ugly in commit 22c877d4 before,
however implement a cleaner solution which is also suitable for
backporting.
Closes#3021259.
(cherry picked from commit 65311ef2b4)
Most files and most of the core classes and their methods have been
renamed to match new coding style conventions:
391 files changed, 25400 insertions(+), 25598 deletions(-)
Furthermore splitted some files where model and view classes were
declared or implemented together in the same file.
Should be tested thoroughly as I might have missed renaming some virtual
methods or SIGNAL/SLOT parameters.
