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.

f28fb76bd9 fix computation of Text bounding box to respect _clamped_width 2013-10-28 12:27:33 -04:00
097b781209 fix computation of canvas text item bounding box 2013-10-24 17:12:28 -04:00
0e656f0a13 workaround/hack/fix for cairo pattern gradient space exceeding 2^16 size limit 2013-06-27 10:41:00 -04:00
f9936d7d3c move text origin back down, since it was a mistake to move it; alter computation of text bounding box to more accurate and efficient (not done yet) 2013-06-26 17:55:42 -04:00
2c3d570582 tweak position of pango-rendered text image on canvas by 2 pixels upward
this is an arbitrary tweak but seems to work well thus far
2013-06-26 12:29:44 -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
a0044e5f71 add back various functionality to waveviews such as zero line, amplitude scaling 2013-04-16 10:07:52 -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
393ba98422 tweak time axis view item text positioning; allow ArdourCanvas::Text to have its width clamped, and use this as TAVI's get narrow so that text doesn't overflow 2013-04-15 14:45:22 -04:00
7e19053b88 Fix dragging objects on the canvas and remove redundant canvas groups
Delivery of fake motion events to the editor needed the event coordinates to be
in canvas space, as they are with "real" events. Editor and other objects had
many redundant groups from timbyr's work on gnomecanvas to scroll by moving
groups. We don't need this anymore with cairo-canvas (though possibly a
stationay background group for the canvas might be useful again one day as in
the SAE logo. Its implementation would be fairly different though, since we
would have to explicitly move the group on every scroll, since nothing else
ever moves on scroll).

Also tweaks to text item placement, and switch TimeAxisViewItem from
name_pixbuf to name_text, since ArdourCanvas::Text is already "pixbuf optimized".

053eaf77fd a variety of fixes for the cairocanvas, but it still buggy as hell handling events and lots of other stuff 2013-04-09 14:22:58 -04:00
1267b1d61c mo' better debugging of canvas "structure" via Item::dump and derivatives 2013-04-08 19:48:09 -04:00
f2f92aaf8c lazy redraw of Canvas::Text image 2013-04-06 19:04:34 -04:00
