102 | * Modify the boundaries to reflect a scale change. (resize) | |
103 | * Refresh the physical screen with the pixmap | |
104 | * A helper function is provided here to convert from time to process | |
105 | * identifier to pixels and the contrary (will be useful for mouse selection). | |
106 | * Insert an empty square in the drawing, moving the bottom part. | |
107 | * | |
108 | * Note: The last point is exactly why it would not be so easy to add the | |
109 | * vertical line functionnality as in the original version of LTT. In order | |
110 | * to do so, we should keep all processes in the list for the duration of | |
111 | * all the trace instead of dynamically adding and removing them when we | |
112 | * scroll. Another possibility is to redraw all the visible area when a new | |
113 | * process is added to the list. The second solution seems more appropriate | |
114 | * to me. | |
115 | * | |
116 | * | |
117 | * The pixmap used has the width of the physical window, but the height | |
118 | * of the shown processes. | |
