Update of /project/gsharp/cvsroot/gsharp In directory clnet:/tmp/cvs-serv8543 Modified Files: buffer.lisp cursor.lisp drawing.lisp gui.lisp measure.lisp Log Message: Alright, let's try this: more correct key signatures, I hope. The major change to the protocol is that REMOVE-ELEMENT takes as a required argument the bar as well as the element; this allows more symmetric methods to be written for the various stealth mixin bits of functionality. Key signatures are elements, as before, within a layer. However, they are also kept on a list sorted by sequence in a slot of the staff, and KEYSIG is responsible for checking the relevant staff for other key signature elements. Editing actions or commands are also responsible for maintaining this list sorted in the right order. New almost-correct function for testing the temporal-and-logical ordering of elements. Drawing code now computes the correct key signature for the each staff; linebreaking is done with a conservative assumption for how wide the key signature will be. Please test. --- /project/gsharp/cvsroot/gsharp/buffer.lisp 2007/06/28 13:56:53 1.48 +++ /project/gsharp/cvsroot/gsharp/buffer.lisp 2007/07/05 21:13:03 1.49 @@ -725,7 +725,7 @@ (defgeneric add-element (element bar position)) ;;; Delete an element from the bar to which it belongs. -(defgeneric remove-element (element)) +(defgeneric remove-element (element bar)) (defclass bar (gsharp-object) ((slice :initform nil :initarg :slice :accessor slice) @@ -768,20 +768,44 @@ (with-slots (elements) b (setf elements (ninsert-element element elements position))) (setf bar b))) -
