| 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. |
