The libgtkwaveform library contains the GtkWaveView sound sample display widget and its corresponding data source objects. The GtkWaveform framework provides a robust caching display interface using the MVC (or Model-View-Controller) paradigm. See the docs directory for an html reference to the GtkWaveView widget and its associated wave data objects. Note that the naming conventions changed in this version. You may use the convert.sh script to fix your *.[ch] files to the new names. Make sure to back up your application first before running the script on its files (just in case).
