|

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