Paul Davis cd99fed7cd canvas: add PolyItem::clear() 2023-09-30 11:09:58 -06:00
Paul Davis de67226c90 provide PolyItem::pop_back() 2023-07-09 20:41:36 -06:00
Paul Davis 91500795d8 canvas: extend PolyItem API with ::add_point() 2023-06-26 14:18:18 -06:00
Paul Davis f913373351 canvas: change Item::bb_clean() to better named Item::set_bbox_clean() 2022-04-26 22:04:08 -06:00
Paul Davis c75ceb31ab canvas: when an item has its bbox marked dirty, this should propagate to all parents 2022-04-26 22:04:08 -06:00
Paul Davis ad6afbe68a canvas: use Item::bb_clean() to mark _bounding_box_dirty false 2021-08-13 12:51:36 -06:00

Remove hardcoded 2^15 cairo-boundary, prefer window-area 2020-04-10 18:28:26 +02:00

NO-OP: whitespace 2020-04-10 18:06:42 +02:00

Remove unused function 
Cairo::curve_to renders cubic Bézier splines, those are not
generally useful in a DAW context.

Canvas::Curve implements centripetal catmull-rom spline drawing
which can be used for fades and automation interpolation.

Update canvas/UI lib GPL boilerplate and (C) from git log 2019-08-03 15:53:17 +02:00
Paul Davis 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

Robin Gareus 22b07e0233 NOOP, remove trailing tabs/whitespace. 2015-10-05 16:17:49 +02:00
Paul Davis 4dc63966f0 globally remove all trailing whitespace from ardour code base. 
Paul Davis was responsible for introducing almost all of this.

Paul Davis c2dcd7eacd slightly increase size of a Canvas::PolyItem, to avoid left-over pixels when dragging (as well as other general incorrectness 2014-06-27 10:30:09 -04:00
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 c2946ee00f don't queue redraws when various canvas item properties are "reset" to the same value, plus supporting functions 2014-03-11 07:36:09 -04:00
Paul Davis 032f394b2a tiny red dots, be gone (expand poly_item bounding box by correct (?) amount) 2014-03-10 11:10:38 -04:00
Paul Davis ec0be1310f missing iterator advance 2014-03-10 11:10:38 -04:00
Paul Davis 621887cfaa slightly optimize bounding box computation for ArdourCanvas::PolyItem by avoiding inner conditional 2014-03-07 11:24:51 -05:00
Paul Davis fbe94f4470 pixel-align canvas PolyItems with single-pixel outlines, for crispness 2014-01-13 09:39:50 -05:00
Paul Davis 7914d45f27 add missing iterator increment to poly item renders. 2014-01-06 20:45:40 -05:00
Paul Davis 4b71d7fde5 small optimization to curve rendering 2014-01-06 20:45:40 -05:00
Paul Davis a585816f3e slight optimization of PolyItem::render_path() 2013-12-28 13:52:08 -05:00
Paul Davis 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
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 a079118981 fix incorrect coordinate space when drawing first poly-curve line 2013-06-21 13:56:01 -04:00
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 37dd7e952b add headers to all canvas .cc and .h files 2013-04-15 22:10:18 -04:00
Paul Davis 64d3763652 remove all xml++.h inclusion by canvas implementations 2013-04-15 22:00:13 -04:00
Paul Davis 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
Paul Davis 7caf517b27 add (bezier) curves to canvas, use for automation lines; fix issue with rectangles missing their upper line segment; more cairo canvas fixes 2013-04-11 22:54:12 -04:00
Paul Davis 1267b1d61c mo' better debugging of canvas "structure" via Item::dump and derivatives 2013-04-08 19:48:09 -04:00
Paul Davis 07a505b1b2 lots of tweaking and adding debug output including operator<</dump(ostream&) methods to help visualize canvas structure 2013-04-05 11:27:26 -04:00
Paul Davis aaea166135 initial commit of hand merging, plus getting "ancient" waf script to work correctly 2013-04-04 00:32:52 -04:00
