b9a010a2 25/* Event hooks are the drawing hooks called during traceset read. They draw the
26 * icons, text, lines and background color corresponding to the events read.
27 *
e92eabaf 28 * Two hooks are used for drawing : before_schedchange and after_schedchange hooks. The
29 * before_schedchange is called before the state update that occurs with an event and
30 * the after_schedchange hook is called after this state update.
b9a010a2 31 *
e92eabaf 32 * The before_schedchange hooks fulfill the task of drawing the visible objects that
33 * corresponds to the data accumulated by the after_schedchange hook.
b9a010a2 34 *
e92eabaf 35 * The after_schedchange hook accumulates the data that need to be shown on the screen
36 * (items) into a queue. Then, the next before_schedchange hook will draw what that
b9a010a2 37 * queue contains. That's the Right Way (TM) of drawing items on the screen,
38 * because we need to draw the background first (and then add icons, text, ...
39 * over it), but we only know the length of a background region once the state
e92eabaf 40 * corresponding to it is over, which happens to be at the next before_schedchange
b9a010a2 41 * hook.
42 *
43 * We also have a hook called at the end of a chunk to draw the information left
44 * undrawn in each process queue. We use the current time as end of
45 * line/background.
