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. | ||
