Right.
I've been looking at this but can't decide which is the better way of
doing it.
BasicCommand only takes a single Segment and I want the method to
present a single colour change to a number of selected segments as one
undo Item (which is logical). There is BasicSelectionCommand but that's
for EventSelections not SegmentSelections (yes, I'm aware at present
SegmentSelections is little more than a glorified typedef).
The basic functionality is easy - I simply do the same thing as
SegmentLabelCommand and derive from KNamedCommand but this doesn't
provide the UpdateRefreshStatuses for free.
Now, should I:
1) Implement the updateRefreshStatuses within the SegmentColourCommand
or
2) Take the time to create a class similar to BasicCommand and
BasicSelectionCommand (maybe BasicSegmentCommand) which can deal with
a Rosegarden::SegmentSelection so that if we need to do something like
this in future, the framework is already there.
