[Rosegarden-devel] Staff, NotationStaff, MatrixStaff

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

I'm planning to introduce a new base-class for NotationStaff
(in gui, so to sit between Staff and NotationStaff).  It will
contain the code to draw staff and bar lines, manage the
relationship between canvas and layout coordinates (relevant
to the notation staff in page mode) and handle those of the
StaffLayout methods that are best handled there.  Does this
sound helpful to your matrix stuff as well?  I assume the
matrix is intended to have staff lines (even if a different
number at different heights) and suchlike too.

Also I will probably trash StaffLayout again; most of the
methods gain nothing from being implemented in the view rather
than a specific staff, and we just need an ad-hoc way to get
hold of the correct staff.
