[Rosegarden-devel] LoopRulers and EditViews

[Chris C. <ca...@al...>]

First some terminology: it seems "pointer" was generally being
used for the playback pointer, so I've stuck with that, and the
insertion pointer was sometimes referred to as a cursor, so I'm
using the term "insert cursor".  Hence "setPointerPosition" etc
for the playback thing, and "setInsertCursorPosition" etc for
the insertion thing.  Most classes should now use these terms,
except currently for RosegardenGUIColours.

Anyway: I've moved the playback pointer code from NotationView
into LinedStaff, removed the StaffRuler, and made the bottom
LoopRuler in the NotationView control the insert cursor instead
of the pointer.  The insert cursor is now a simple line owned
by the LinedStaff, instead of an ActiveItem owned by the
StaffRuler.  (That's just because I coded it by cut-&-paste
from the playback pointer code: obviously it could become an
ActiveItem again, but I thought that might wait because you were
talking about making it a widget or something.)

It should be trivial to make the pointers work in the matrix:
just connect up the signals as in the NotationView, and do as
in NotationView::slotSetPointerPosition and
slotSetInsertCursorPosition (although much simpler because
there's only one staff in the matrix).

There's a bit more work to be done but I don't think I'll have
time today -- shouldn't overlap too much with anything you might
be doing.  There are some disgustingly bright colours involved
now, but I'll change those later...
