5c7463ed 5 * \brief Graphical plugin for showing events.
6 *
17abcce3 7 * This plugin lists all the events contained in the current time interval
8 * in a list.
9 *
5c7463ed 10 * This plugin adds a Events Viewer functionnality to Linux TraceToolkit
11 * GUI when this plugin is loaded. The init and destroy functions add the
12 * viewer's insertion menu item and toolbar icon by calling gtkTraceSet's
13 * API functions. Then, when a viewer's object is created, the constructor
14 * creates ans register through API functions what is needed to interact
15 * with the TraceSet window.
16 *
fbbb2697 17 * Coding standard :
18 * pm : parameter
19 * l : local
20 * g : global
21 * s : static
22 * h : hook
23 *
fcdf0ec2 24 * Author : Karim Yaghmour
