From 77f16522e0b396262bc272c1637753faa9da0ba7 Mon Sep 17 00:00:00 2001 From: Carl Hetherington Date: Fri, 19 Oct 2007 13:30:07 +0000 Subject: Various work on bundles. We now have a Bundle Manager dialogue, and hopefully things are a bit cleaner internally. This commit changes the session file format with respect to bundles (or Connections as they used to be called). git-svn-id: svn://localhost/ardour2/trunk@2561 d708f5d6-7413-0410-9779-e7cbd77b26cf --- gtk2_ardour/io_selector.cc | 747 +++++---------------------------------------- 1 file changed, 68 insertions(+), 679 deletions(-) (limited to 'gtk2_ardour/io_selector.cc') diff --git a/gtk2_ardour/io_selector.cc b/gtk2_ardour/io_selector.cc index d0f236f84a..b8598659d7 100644 --- a/gtk2_ardour/io_selector.cc +++ b/gtk2_ardour/io_selector.cc @@ -17,15 +17,6 @@ */ -#include -#include -#include -#include -#include -#include -#include -#include -#include #include #include #include @@ -41,575 +32,116 @@ #include "gui_thread.h" #include "i18n.h" -/** Add a port to a group. - * @param p Port name, with or without prefix. - */ - -void -PortGroup::add (std::string const & p) -{ - if (prefix.empty() == false && p.substr (0, prefix.length()) == prefix) { - ports.push_back (p.substr (prefix.length()));
