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.

b54a2713a1 When rendering a Canvas::Rectangle take its _position into account, even though in general this is always (0,0) within its parent 2014-06-06 08:33:13 -04:00
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
52c8b6d66a stupid hack to fix rectangle damage noise 2014-03-09 11:39:57 -04:00
6d3bd4e53c use fill transparency detection to avoid rendering transparent (invisible) rectangle fill area 2014-03-07 12:29:26 -05:00
737aae908a tweak canvas rect drawing to correctly place bottom edge of rectangle inside the bounds (cairo works in mysterious ways) 2014-02-25 12:02:50 -05:00
1df483d3db since we now expand rectangles to the right always, adjust the bounding box computation 2014-02-14 09:49:16 -05:00
1a9076c0ba remove debug message 2014-02-13 18:18:53 -05:00
08b86fda5c fix up some issues with precise placement of ArdourCanvas::Rectangle frame/outline 2014-02-13 18:18:19 -05:00
f889f391a1 Guard some Debug output so that it only appears when applicable ('Item::name' is only available when CANVAS_DEBUG is defined) 2014-02-13 14:12:36 +00:00
22c303d8f6 final (?) tweaks to rectangle rendering 2014-01-10 14:36:05 -05:00
cf293d0593 tweak rectangle bounding box computation 2014-01-08 10:42:14 -05:00
c235d3da99 mostly fix conceptual error in how canvas rectangle frames are drawn 2014-01-07 20:56:36 -05:00
b46244d527 finally (?) fix up logic for rectangle drawing (fill+stroke) to tackle what is hopefully the last of the expose problems 2013-10-31 11:49:36 -04:00
9d2e4fbec6 fix computation of rectangle bounding box 2013-10-24 17:13:03 -04:00
144fdfbbd0 fix drawing of rectangles larger than 2000 pixels, caused by silly hard-coding of width limit 2013-06-27 17:27:58 -04:00
0e656f0a13 workaround/hack/fix for cairo pattern gradient space exceeding 2^16 size limit 2013-06-27 10:41:00 -04:00
a1f858d3b2 an awful lot of tweaks to drawing details 2013-06-24 16:28:53 -04:00
691be68ac2 fix rect redraw problems caused by intersection requiring the usual 0.5 expansion (though consider a more general fix for this at teh group level) 2013-06-18 13:46:24 -04:00
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
c358e77e1e move setup_outline_context() to a more sensible shared location 2013-05-02 18:21:35 -04:00
d1a05240ef fix clamping of line and rect coordinates to avoid issues with cairo when drawing way outside a surface's dimensions; move various coordinate methods down to Canvas, because they don't require GTK information; make visible_area() a Canvas virtual method so that we don't have to cast to call it 2013-04-17 10:53:17 -04:00
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
4258a34912 change all frame_to_pixel and pixel_to_frame to sample_to_pixel and pixel_to_sample 2013-04-12 11:15:45 -04:00
fcb423f3f6 slightly optimize drawing of rectangles with all 4 sides outlined to avoid multiple paths etc 2013-04-12 11:08:24 -04:00
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
aaea166135 initial commit of hand merging, plus getting "ancient" waf script to work correctly 2013-04-04 00:32:52 -04:00
