76a67e8a | 37 | * Draw horizontal lines, getting graphic context as arg. |
fa2c4dbe | 38 | * Copy region of the screen into another. |
76a67e8a | 39 | * Modify the boundaries to reflect a scale change. (resize) |
847b479d | 40 | * Refresh the physical screen with the pixmap |
189a5d08 | 41 | * A helper function is provided here to convert from time to process |
fa2c4dbe | 42 | * identifier to pixels and the contrary (will be useful for mouse selection). |
5f16133f | 43 | * Insert an empty square in the drawing, moving the bottom part. |
44 | * | |
189a5d08 | 45 | * Note: The last point is exactly why it would not be so easy to add the |
46 | * vertical line functionnality as in the original version of LTT. In order | |
47 | * to do so, we should keep all processes in the list for the duration of | |
48 | * all the trace instead of dynamically adding and removing them when we | |
49 | * scroll. Another possibility is to redraw all the visible area when a new | |
50 | * process is added to the list. The second solution seems more appropriate | |
51 | * to me. | |
52 | * | |
53 | * | |
5f16133f | 54 | * The pixmap used has the width of the physical window, but the height |
55 | * of the shown processes. | |
