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. |

916 | * This function basically draw lines and icons. Two types of lines are drawn : |
917 | * one small (3 pixels?) representing the state of the process and the second |
918 | * type is thicker (10 pixels?) representing on which CPU a process is running |
919 | * (and this only in running state). |
920 | * |
921 | * Extremums of the lines : |
922 | * x_min : time of the last event context for this process kept in memory. |
923 | * x_max : time of the current event. |
924 | * y : middle of the process in the process list. The process is found in the |
925 | * list, therefore is it's position in pixels. |
926 | * |
927 | * The choice of lines'color is defined by the context of the last event for this |
928 | * process. |
