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

0c170b0897 no create cached waveview images that span from render-start to cache-start, but always clamp the end to render-end, to avoid creating over-sized images 2013-04-19 10:53:52 -04:00

8f2a2877b5 ArdourCanvas::Image allow to set custom data instead of class pre-allocated memory. 2013-04-17 20:26:09 +02:00
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
96eee9e7a1 change UIConfig to use accessor/setter methods like RCConfig so that ParameterChanged methods can actually be emitted; add variable (over a small range) background shading for all TimeAxisViewItems 2013-04-16 23:46:22 -04:00
381d4debf4 make waveform gradient depth continuously variable. color probably needs adjusting as do color stops to get a pleasing effect at most settings 2013-04-16 21:23:50 -04:00
c1df3295c1 virtual Fill:: and Outline:: methods so that Canvas::Items that cache image renderings of themselves can invalidate those caches when colors etc. change; add Item::{begin,end}_visual_change() so that we can notify the canvas more efficiently when *only* visual properties have changed and not the bounding box (probably needs to be used more widely) 2013-04-16 20:38:10 -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
fe34485907 add new canvas Image item, with somewhat optimized API for asynchronous, threaded rendering directly into an image buffer suitable for use by cairo as a source surface (currently untested) 2013-04-15 21:40:15 -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".

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
4e84bc3a39 changes to get cairocanvas branch to build on OS X, with its stupid nil and Rect macros, plus some const_cast<> and unused variable fixes that should really be in master but will have to wait till we rebase master 2013-04-12 21:46:44 -04:00
e5a3747686 switch from frames_per_pixel to samples_per_pixel in the one canvas object that uses this 2013-04-12 11:31:17 -04:00
