5 | * \brief Graphical plugin for showing control flow of a trace. |
6 | * |
7 | * This plugin adds a Control Flow Viewer functionnality to Linux TraceToolkit |
8 | * GUI when this plugin is loaded. The init and destroy functions add the |
9 | * viewer's insertion menu item and toolbar icon by calling gtkTraceSet's |
10 | * API functions. Then, when a viewer's object is created, the constructor |
11 | * creates ans register through API functions what is needed to interact |
12 | * with the TraceSet window. |
13 | * |
14 | * This plugin uses the gdk library to draw the events and gtk to interact |
15 | * with the user. |
