2691209050 When removing an item which is event-insensitive, there is no need to repick the current item, since it can never have been used as the current item.
This fixes crashes associated with ghost notes in midi regions.

2d283c17e1 remove unused code 2014-01-08 10:28:46 -05:00
2d50adaf3a ignore invisible items when picking the current item
Also left behind some commented debug out that probably deserves a new PBD::Debug bit.

84f55440a3 fix redrawing of canvas with an optimized build
Best guess right now is that optimization does something bad when ceil() is called twice on a very large dbl-precision number,
which results in a zero (empty) redraw area. Without the removal of the redundant ceil & floor functions, no expose events
would be delivered to the canvas in an optimized build during drags (and maybe more).

4780c84252 debug trace tweaks 2013-12-09 13:38:22 -05:00
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

08b485db75 send enter events to EVERY newly entered item (ignore the bool return from the event handler); other canvas debugging aids;switch items_at_point() to use canvas coordinates 2013-11-03 10:07:00 -05:00
85daa31ab5 all events propagate out of the canvas in canvas coordinates now, so revert changes in editor_drags.cc that worked around this not being the case 2013-10-31 16:43:35 -04:00
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

c3f1369cfd expand bounding box of all objects by 0.5 before computing intersection for render cycle; alter debug output 2013-10-24 17:14:12 -04:00
18850253e9 only generate some current canvas debug output when CANVAS_DEBUG is defined, to quieten things down 2013-09-25 10:38:04 -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

6f664c1f67 many pervasive changes primarily related to waveform drawing, particular content-dragging, colors, and more 2013-04-24 15:42:14 -04:00
9a3bc39970 tweak event/leave event delivery so that it applies to items being deleted as well as motion events (hmm, needed for item addition too ...) 2013-04-20 16:11:40 -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

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
af4539f857 a few changes to fix region dragging, all related to coordinate system handling, which is now much simpler with the new canvas; more debugging output when asked for 2013-04-15 10:38:12 -04:00
ee1f0520a8 many changes to get the cairo-canvas version much, much more functional. still problems with a lot of subtle and not-so-subtle issues 2013-04-11 20:19:22 -04:00
