24 * \brief Graphical plugin for showing events.
25 *
26 * This plugin lists all the events contained in the current time interval
27 * in a list.
28 *
29 * This plugin adds a Events Viewer functionnality to Linux TraceToolkit
30 * GUI when this plugin is loaded. The init and destroy functions add the
31 * viewer's insertion menu item and toolbar icon by calling viewer.h's
32 * API functions. Then, when a viewer's object is created, the constructor
33 * creates ans register through API functions what is needed to interact
34 * with the lttvwindow.
35 *
36 * Authors : Mathieu Desnoyers and XangXiu Yang, June to December 2003
37 * Inspired from original LTT, made by Karim Yaghmour
