189a5d08 | 64 | * Note: The last point is exactly why it would not be so easy to add the |
65 | * vertical line functionnality as in the original version of LTT. In order | |
66 | * to do so, we should keep all processes in the list for the duration of | |
67 | * all the trace instead of dynamically adding and removing them when we | |
68 | * scroll. Another possibility is to redraw all the visible area when a new | |
69 | * process is added to the list. The second solution seems more appropriate | |
70 | * to me. | |

72 | * | |
5f16133f | 73 | * The pixmap used has the width of the physical window, but the height |
74 | * of the shown processes. | |
