Update of /project/gsharp/cvsroot/gsharp In directory cl-net:/tmp/cvs-serv25231 Modified Files: buffer.lisp cursor.lisp drawing.lisp gui.lisp melody.lisp packages.lisp score-pane.lisp Log Message: Basic time signature support. Only some sigs supported and spacing is basic. Key and time signatures now share a staffwise-elements slot in the stave. --- /project/gsharp/cvsroot/gsharp/buffer.lisp 2008/02/09 16:58:35 1.59 +++ /project/gsharp/cvsroot/gsharp/buffer.lisp 2009/04/20 15:04:47 1.60 @@ -208,8 +208,8 @@ ;; there might be more than one key signature in the bar, ;; and they might have changed their relative order as a ;; result of the edit. - (setf (key-signatures staff) - (sort (key-signatures staff) + (setf (staffwise-elements staff) + (sort (staffwise-elements staff) (lambda (x y) (gsharp::starts-before-p x (bar y) y)))))))))) (defmethod add-element :after ((element element) (bar bar) position) --- /project/gsharp/cvsroot/gsharp/cursor.lisp 2008/11/19 16:05:13 1.8 +++ /project/gsharp/cvsroot/gsharp/cursor.lisp 2009/04/20 15:04:47 1.9 @@ -166,10 +166,10 @@ (when (> (pos cursor) position) (incf (pos cursor))))) -(defmethod add-element :after ((keysig key-signature) bar position) - (let ((staff (staff keysig))) - (setf (key-signatures staff) - (merge 'list (list keysig) (key-signatures staff) +(defmethod add-element :after ((element staffwise-element) bar position) + (let ((staff (staff element))) + (setf (staffwise-elements staff) + (merge 'list (list element) (staffwise-elements staff) (lambda (x y) (gsharp::starts-before-p x (bar y) y)))))) (defmethod remove-element :before ((element element) (bar cbar)) --- /project/gsharp/cvsroot/gsharp/drawing.lisp 2008/11/19 16:05:13 1.87 +++ /project/gsharp/cvsroot/gsharp/drawing.lisp 2009/04/20 15:04:47 1.88 @@ -162,6 +162,13 @@ (score-pane:staff-step 5) (score-pane:staff-step 2))) +(defmethod right-bulge ((timesig time-signature) pane) + ;; FIXME: this is probably wrong; it should either compute the bulge + ;; properly, or else approximate using (length - 0.5) * + ;; typical-width-of-component + (* (length (time-signature-components timesig)) + (score-pane:staff-step 5))) + (defmethod right-bulge ((keysig key-signature) pane) ;; FIXME: shares much code with DRAW-ELEMENT (KEY-SIGNATURE).
