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 | * | |
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. | |
31 | * | |
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. | |
34 | * | |
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 | |
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 | |
40 | * corresponding to it is over, which happens to be at the next before_schedchange | |
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. | |
