69 | * Refresh the physical screen with the pixmap |
70 | * A helper function is provided here to convert from time to process |
71 | * identifier to pixels and the contrary (will be useful for mouse selection). |
72 | * Insert an empty square in the drawing, moving the bottom part. |
73 | * |
74 | * Note: The last point is exactly why it would not be so easy to add the |
75 | * vertical line functionnality as in the original version of LTT. In order |
76 | * to do so, we should keep all processes in the list for the duration of |
77 | * all the trace instead of dynamically adding and removing them when we |
78 | * scroll. Another possibility is to redraw all the visible area when a new |
79 | * process is added to the list. The second solution seems more appropriate |
80 | * to me. |
81 | * |
82 | * |
83 | * The pixmap used has the width of the physical window, but the height |
84 | * of the shown processes. |
