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 |
5ac76b22 |
29 | * viewer's insertion menu item and toolbar icon by calling viewer.h's |
f0d936c0 |
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. |
