25 * \brief Graphical plugin for showing control flow of a trace.
27 * This plugin adds a Control Flow Viewer functionnality to Linux TraceToolkit
28 * GUI when this plugin is loaded. The init and destroy functions add the
29 * viewer's insertion menu item and toolbar icon by calling viewer.h's
30 * API functions. Then, when a viewer's object is created, the constructor
31 * creates ans register through API functions what is needed to interact
32 * with the TraceSet window.
34 * This plugin uses the gdk library to draw the events and gtk to interact
