| 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. |
