76a67e8a 54 * Draw horizontal lines, getting graphic context as arg.
fa2c4dbe 55 * Copy region of the screen into another.
76a67e8a 56 * Modify the boundaries to reflect a scale change. (resize)
847b479d 57 * Refresh the physical screen with the pixmap
189a5d08 58 * A helper function is provided here to convert from time to process
fa2c4dbe 59 * identifier to pixels and the contrary (will be useful for mouse selection).
5f16133f 60 * Insert an empty square in the drawing, moving the bottom part.
61 *
189a5d08 62 * Note: The last point is exactly why it would not be so easy to add the
63 * vertical line functionnality as in the original version of LTT. In order
64 * to do so, we should keep all processes in the list for the duration of
65 * all the trace instead of dynamically adding and removing them when we
66 * scroll. Another possibility is to redraw all the visible area when a new
67 * process is added to the list. The second solution seems more appropriate
68 * to me.
69 *
70 *
5f16133f 71 * The pixmap used has the width of the physical window, but the height
72 * of the shown processes.
