5c7463ed 25 * \brief Graphical plugin for showing events.
26 *
17abcce3 27 * This plugin lists all the events contained in the current time interval
28 * in a list.
29 *
5c7463ed 30 * This plugin adds a Events Viewer functionnality to Linux TraceToolkit
31 * GUI when this plugin is loaded. The init and destroy functions add the
5ac76b22 32 * viewer's insertion menu item and toolbar icon by calling viewer.h's
5c7463ed 33 * API functions. Then, when a viewer's object is created, the constructor
34 * creates ans register through API functions what is needed to interact
b72d54c9 35 * with the lttvwindow.
5c7463ed 36 *
8a949012 37 * Authors : Mathieu Desnoyers and XangXiu Yang, June to December 2003
38 * Inspired from original LTT, made by Karim Yaghmour
1193dd68 39 *
40 * Mostly rewritten by Mathieu Desnoyers, August 2005.
