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.

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
97109672c7 initial redesign of canvas scrolling to facilitate independent x- and y-axis scrolling of specific groups within the canvas.
This commit should cause no change in behaviour, but contains all the code and changes necessary
for the next step

e2f18ea658 allow per-line configurability of the threshold used to determine if a PolyLine covers a given coordination 2014-02-20 12:53:08 -05:00
14b2d0b549 fix error in canvas PolyLine::covers(), so that the mouse can actually enter/leave such items 2014-02-19 23:42:01 -05:00
c4f0063a68 make PolyLine use distance_to_segment_squared(), and add separate (null, for now) method Curve::covers(Duple) because the math there needs to be different, maybe 2013-12-09 17:24:34 -05:00
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

37dd7e952b add headers to all canvas .cc and .h files 2013-04-15 22:10:18 -04:00
64d3763652 remove all xml++.h inclusion by canvas implementations 2013-04-15 22:00:13 -04:00
84fb0a8dce remove all XML related API from canvas. it may have been useful during development, but it is just a distraction - we will NEVER be saving or restoring canvas state via XML or any kind of serialized state 2013-04-15 21:57:08 -04:00
aaea166135 initial commit of hand merging, plus getting "ancient" waf script to work correctly 2013-04-04 00:32:52 -04:00
