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. |
