23 * Changes by Clifford Wolf (god@clifford.at)
24 *
25 * [ 1998-06-13 ]
26 *
27 * *) A bugfix for the Page-Down problem
28 *
29 * *) Formerly when I used Page Down and Page Up, the cursor would be set
30 * to the first position in the menu box. Now lxdialog is a bit
31 * smarter and works more like other menu systems (just have a look at
32 * it).
33 *
34 * *) Formerly if I selected something my scrolling would be broken because
35 * lxdialog is re-invoked by the Menuconfig shell script, can't
36 * remember the last scrolling position, and just sets it so that the
37 * cursor is at the bottom of the box. Now it writes the temporary file
38 * lxdialog.scrltmp which contains this information. The file is
39 * deleted by lxdialog if the user leaves a submenu or enters a new
40 * one, but it would be nice if Menuconfig could make another "rm -f"
41 * just to be sure. Just try it out - you will recognise a difference!
42 *
43 * [ 1998-06-14 ]
44 *
45 * *) Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
46 * and menus change their size on the fly.
47 *
48 * *) If for some reason the last scrolling position is not saved by
49 * lxdialog, it sets the scrolling so that the selected item is in the
50 * middle of the menu box, not at the bottom.
51 *
52 * 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
53 * Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
54 * This fixes a bug in Menuconfig where using ' ' to descend into menus
55 * would leave mis-synchronized lxdialog.scrltmp files lying around,
56 * fscanf would read in 'scroll', and eventually that value would get used.
