From 337fae8183800ecd4967206507e16f285b34e88d Mon Sep 17 00:00:00 2001 From: Nick Mainsbridge Date: Tue, 19 May 2009 14:38:37 +0000 Subject: [PATCH] Fix record crash, use pixfufs instead of canvas text in markers, use leftmost_frame instead of querying canvas coords when scrolling (speeds up canvas scrolling somewhat). git-svn-id: svn://localhost/ardour2/branches/2.0-ongoing@5101 d708f5d6-7413-0410-9779-e7cbd77b26cf --- gtk2_ardour/editor.cc | 7 +-- gtk2_ardour/editor.h | 4 -- gtk2_ardour/editor_canvas.cc | 36 ++++----------- gtk2_ardour/marker.cc | 74 ++++++++++++++++++++---------- gtk2_ardour/marker.h | 11 +++-- gtk2_ardour/time_axis_view_item.cc | 37 ++------------- gtk2_ardour/utils.cc | 31 +++++++++++++ gtk2_ardour/utils.h | 6 +++ 8 files changed, 110 insertions(+), 96 deletions(-) diff --git a/gtk2_ardour/editor.cc b/gtk2_ardour/editor.cc index d8902f8ece..6bb2526750 100644 --- a/gtk2_ardour/editor.cc +++ b/gtk2_ardour/editor.cc @@ -294,7 +294,6 @@ Editor::Editor () _show_measures = true;
