Stem-export defaults to use selected tracks. This retains
the selection, so focus remains. Repeat stem export will use
previously exported tracks if the selection is empty, or the
current selection (again).
This splits apart the actual signal handler from the work that needs to be done
to update the GUI in response to a tempo map change. This allows us to do the
visual update when we are manipulating the thread-local write copy of the map
during e.g. a drag operation.
This commit leaves two issues outstanding:
1. unclear/ugly semantics for drag operations that reset the GUI thread's tempo map to the writable copy
2. undo/redo for the tempo map
These will be addressed in future commits
This allows it to be used in an idle callback. If we use
::redisplay_track_views() directly, we do not disconnect the idle
connection. This will happen automatically since the callback will return
false, but it seems better to explicit about this. Even better would be to use
::connect_once() but this may not be available in the version of glibmm that we
are using at present.
The track-height change needs to be applied so that
vertical_adjustment max range is set correctly.
Otherwise vertical_adjustment.set_value() may fail
or scroll to the wrong position.
In 5b3eacd421 `redisplay_track_views()` was moved from
EditorRoutes to Editor. The call was delegated to the idle
thread, potentially collecting multiple calls before performing
the update.
This resulted in "Fit selection" to set the y-offset before the
height-change was applied.
Major changes: do not delete and recreate markers and curves for every tempo map
change, attach tempo curves directly to their (preceding) tempo marker, notable
cleanup of TempoCurve class to remove unnecessary members.
More tweaks expected since algorithm for matching markers and tempo map
points is not correct yet.
After beginning an edit operation with TempoMap::write_copy(), the tempoPoint and meterPoint objects
referenced by markers are incorrect, since they refer to the original map, not the copy we are working
on. Fix this with Editor::reassociate_metric_markers()
Some instances requiring this fix may still remain
