Update canvas/UI lib GPL boilerplate and (C) from git log 2019-08-03 15:53:17 +02:00
4fa4b9a135 remove use of boost::optional to define "undefined" Canvas::Rect, and use Rect::empty instead.
This commit includes Rect::operator bool() which might be a candidate for removal in a future commit, in an attempt
to make the meaning clearer

22b07e0233 NOOP, remove trailing tabs/whitespace. 2015-10-05 16:17:49 +02:00
9266e7524a experimental drawing optimization.
Q: is bounding_box(); etc more complex than queuing draw?

either way, canvas should eventually switch to
use an optimized OptimizingLookupTable.

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
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
88732abd01 change event propagation to be based on parent/child lineage, not z-axis stacking, plus some more alterations to try to get enter/leave working 2013-12-12 10:03:33 -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

08b485db75 send enter events to EVERY newly entered item (ignore the bool return from the event handler); other canvas debugging aids;switch items_at_point() to use canvas coordinates 2013-11-03 10:07:00 -05:00
30263a91d7 fix coordinate system for Canvas items_at_point() methods 2013-10-28 16:35:31 -04:00
1eb680f937 add coordinate space comment 2013-10-28 12:27:03 -04:00
67bb9a732a add casting for MSVC sqrt 2013-09-25 10:36:42 -04:00
37dd7e952b add headers to all canvas .cc and .h files 2013-04-15 22:10:18 -04:00
aaea166135 initial commit of hand merging, plus getting "ancient" waf script to work correctly 2013-04-04 00:32:52 -04:00
