Paul Davis f913373351 canvas: change Item::bb_clean() to better named Item::set_bbox_clean() 2022-04-26 22:04:08 -06:00

gtkmm: use size_request() function instead of deprecated Gtk::Widget::size_request(&) 2022-04-08 21:11:07 +02:00
Paul Davis 63a74d0911 Canvas: improve behavior of Widget::compute_bounding_box() 
Firstly, ::compute_bounding_box() cannot allocate space, so do not try to do that here.
Secondly, if there is no allocation yet, use the CairoWidget's own size_request()

Remove unused #include<> (2/2) 
PBD::stacktrace() is not used nor needed by default.
It should be used sparingly.

Robin Gareus d06de26a4f Towards a consistent render() API. 
This fixes an -Woverloaded-virtual ambiguity introduced in b5e613d45

  void render (cairo_t*, cairo_rectagle*)
  void render (Cairo::RefPtr<Cairo::Context> const&, cairo_rectangle_t*)

ArdourCanvas prefers cairomm and CairoWidget itself uses Cairo::Context,
this improves overall API consistency.

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

David Robillard bd577a0663 Avoid possible use of uninitialized values. 
This could only happen with a broken widget, but it shuts up clang and doesn't
hurt.

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.
