Paul Davis	a8bd6ecc4f	refactor Canvas so that all Items have children; add Container abstract base class; rename Group as "Layout" and retain only drawing semantics	2014-06-21 11:43:42 -04:00
Paul Davis	590882f3c8	change Canvas heirarchy and constructors ... Items no longer need a parent group (they require a Canvas pointer instead), so all constructors have been rationalized and have two variants, one with a parent and one with a canvas. All Items now inherit from Fill and Outline, to banish diagonal inheritance and virtual base classes and all that. There were zero changes to the Ardour GUI arising from these changes.	2014-06-12 14:53:44 -04:00
Paul Davis	073df89c4d	use window-based coordinates when picking current item so that we get per-item (per-scroll-group,really) computation of position and coverage.	2014-06-03 16:12:00 -04:00
Paul Davis	6473cc7cb4	drop use of bounding box to determine whether an item covers a point; add Item::covers(Duple const&) ... Default implementation for Item still uses bounding box, but specializations for Arc (Circle), Polygon, Line and PolyLine have been added	2013-11-04 11:56:10 -05:00
Paul Davis	77f5f4c4bf	basically operational switch to canvas drawing coordinates, although text and waves don't work, and redraw areas are too small	2013-06-18 08:23:06 -04:00
Paul Davis	8482ce14ce	add Canvas::Arc and derive Canvas::Circle from it	2013-04-18 21:28:11 -04:00
