refactor Canvas so that all Items have children; add Container abstract base class; rename Group as "Layout" and retain only drawing semantics

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.

When rendering a Canvas::Rectangle take its _position into account, even though in general this is always (0,0) within its parent

don't queue redraws when various canvas item properties are "reset" to the same value, plus supporting functions

stupid hack to fix rectangle damage noise

use fill transparency detection to avoid rendering transparent (invisible) rectangle fill area

tweak canvas rect drawing to correctly place bottom edge of rectangle inside the bounds (cairo works in mysterious ways)

since we now expand rectangles to the right always, adjust the bounding box computation

Guard some Debug output so that it only appears when applicable ('Item::name' is only available when CANVAS_DEBUG is defined)

final (?) tweaks to rectangle rendering

mostly fix conceptual error in how canvas rectangle frames are drawn
2014-01-07 20:56:36 -05:00

finally (?) fix up logic for rectangle drawing (fill+stroke) to tackle what is hopefully the last of the expose problems

fix drawing of rectangles larger than 2000 pixels, caused by silly hard-coding of width limit

an awful lot of tweaks to drawing details

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

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

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

add headers to all canvas .cc and .h files

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

change all frame_to_pixel and pixel_to_frame to sample_to_pixel and pixel_to_sample

add (bezier) curves to canvas, use for automation lines; fix issue with rectangles missing their upper line segment; more cairo canvas fixes
