cf6cb7e0 | 23 | * |
24 | * This file contains methods responsible for drawing a generic type of data | |
25 | * in a drawable. Doing this generically will permit user defined drawing | |
26 | * behavior in a later time. | |
27 | * | |
b782dd11 | 28 | * This file provides an API which is meant to be reusable for all viewers that |
29 | * need to show information in line, icon, text, background or point form in | |
30 | * a drawable area having time for x axis. The y axis, in the control flow | |
31 | * viewer case, is corresponding to the different processes, but it can be | |
32 | * reused integrally for cpu, and eventually locks, buffers, network | |
33 | * interfaces... What will differ between the viewers is the precise | |
34 | * information which interests us. We may think that the most useful | |
35 | * information for control flow are some specific events, like schedule | |
36 | * change, and processes'states. It may differ for a cpu viewer : the | |
37 | * interesting information could be more the execution mode of each cpu. | |
38 | * This API in meant to make viewer's writers life easier : it will become | |
39 | * a simple choice of icons and line types for the precise information | |
40 | * the viewer has to provide (agremented with keeping supplementary records | |
41 | * and modifying slightly the DrawContext to suit the needs.) | |
42 | * | |
f0728492 | 43 | * We keep each data type in attributes, keys to specific information |
44 | * being formed from the GQuark corresponding to the information received. | |
45 | * (facilities / facility_name / events / eventname.) | |
46 | * (cpus/cpu_name, process_states/ps_name, | |
47 | * execution_modes/em_name, execution_submodes/es_name). | |
cf6cb7e0 | 48 | * The goal is then to provide a generic way to print information on the |
49 | * screen for all this different information. | |
50 | * | |
51 | * Information can be printed as | |
52 | * | |
53 | * - text (text + color + size + position (over or under line) | |
54 | * - icon (icon filename, corresponding to a loaded icon, accessible through | |
55 | * a GQuark. Icons are loaded statically at the guiControlFlow level during | |
56 | * module initialization and can be added on the fly if not present in the | |
57 | * GQuark.) The habitual place for xpm icons is in | |
58 | * ${prefix}/share/LinuxTraceToolkit.) + position (over or under line) | |
59 | * - line (color, width, style) | |
189a5d08 | 60 | * - Arc (big points) (color, size) |
cf6cb7e0 | 61 | * - background color (color) |
62 | * | |
189a5d08 | 63 | * An item is a leaf of the attributes tree. It is, in that case, including |
64 | * all kind of events categories we can have. It then associates each category | |
65 | * with one or more actions (drawing something) or nothing. | |
66 | * | |
7d5ffafa | 67 | * Each item has an array of hooks (hook list). Each hook represents an |
68 | * operation to perform. We seek the array each time we want to | |
a2e850ff | 69 | * draw an item. We execute each operation in order. An operation type |
70 | * is associated with each hook to permit user listing and modification | |
71 | * of these operations. The operation type is also used to find the | |
72 | * corresponding priority for the sorting. Operation type and priorities | |
73 | * are enum and a static int table. | |
cf6cb7e0 | 74 | * |
75 | * The array has to be sorted by priority each time we add a task in it. | |
a2e850ff | 76 | * A priority is associated with each operation type. It permits |
cf6cb7e0 | 77 | * to perform background color selection before line or text drawing. We also |
78 | * draw lines before text, so the text appears over the lines. | |
79 | * | |
80 | * Executing all the arrays of operations for a specific event (which | |
81 | * implies information for state, event, cpu, execution mode and submode) | |
82 | * has to be done in a same DrawContext. The goal there is to keep the offset | |
83 | * of the text and icons over and under the middle line, so a specific | |
84 | * event could be printed as ( R Si 0 for running, scheduled in, cpu 0 ), | |
7d5ffafa | 85 | * text being easy to replace with icons. The DrawContext is passed as |
86 | * call_data for the operation hooks. | |
cf6cb7e0 | 87 | * |
b782dd11 | 88 | * We use the lttv global attributes to keep track of the loaded icons. |
89 | * If we need an icon, we look for it in the icons / icon name pathname. | |
90 | * If found, we use the pointer to it. If not, we load the pixmap in | |
1a31868c | 91 | * memory and set the pointer to the GdkPixmap in the attributes. The |
92 | * structure pointed to contains the pixmap and the mask bitmap. | |
