| 25 | * \brief Graphical plugin for showing control flow of a trace. |
| 26 | * |
| 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. |
| 33 | * |
| 34 | * This plugin uses the gdk library to draw the events and gtk to interact |
| 35 | * with the user. |
