/********************************************************************** Audacity: A Digital Audio Editor Tags.cpp Dominic Mazzoni *******************************************************************//** \class Tags \brief ID3 Tags (for MP3) This class started as an ID3 tag This class holds a few informational tags, such as Title, Author, etc. that can be associated with a project or other audio file. It is modeled after the ID3 format for MP3 files, and it can both import and export ID3 tags from/to MP2, MP3, and AIFF files. It can present the user with a dialog for editing this information. Use of this functionality requires that libid3tag be compiled in with Audacity. *//****************************************************************//** \class TagsEditor \brief Derived from ExpandingToolBar, this dialog allows editing of Tags. *//*******************************************************************/ // For compilers that support precompilation, includes "wx/wx.h". #include #ifndef WX_PRECOMP // Include your minimal set of headers here, or wx.h #include #endif #include "Tags.h" #include "Audacity.h" #include "FileDialog.h" #include "FileNames.h" #include "Internat.h" #include "Prefs.h" #include "ShuttleGui.h" #include "widgets/Grid.h" #include "xml/XMLFileReader.h" #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #ifdef _DEBUG #ifdef _MSC_VER #undef THIS_FILE static char*THIS_FILE= __FILE__; #define new new(_NORMAL_BLOCK, THIS_FILE, __LINE__) #endif #endif static const wxChar *DefaultGenres[] = { wxT("Blues"), wxT("Classic Rock"), wxT("Country"), wxT("Dance"), wxT("Disco"), wxT("Funk"), wxT("Grunge"), wxT("Hip-Hop"), wxT("Jazz"), wxT("Metal"), wxT("New Age"), wxT("Oldies"), wxT("Other"), wxT("Pop"), wxT("R&B"), wxT("Rap"), wxT("Reggae"), wxT("Rock"), wxT("Techno"), wxT("Industrial"), wxT("Alternative"), wxT("Ska"), wxT("Death Metal"), wxT("Pranks"), wxT("Soundtrack"), wxT("Euro-Techno"), wxT("Ambient"), wxT("Trip-Hop"), wxT("Vocal"), wxT("Jazz+Funk"), wxT("Fusion"), wxT("Trance"), wxT("Classical"), wxT("Instrumental"), wxT("Acid"), wxT("House"), wxT("Game"), wxT("Sound Clip"), wxT("Gospel"), wxT("Noise"), wxT("Alt.
