|
* HISTORY:
|
|
*
|
|
* 17/12/93 - Version 0.1 released.
|
|
*
|
|
* 19/12/93 - menu will now scroll if there are more items than can fit
|
|
* on the screen.
|
|
* - added 'checklist', a dialog box with a list of options that
|
|
* can be turned on or off. A list of options that are on is
|
|
* returned on exit.
|
|
*
|
|
* 20/12/93 - Version 0.15 released.
|
|
*
|
|
* 29/12/93 - Incorporated patch from Patrick J. Volkerding
|
|
* (volkerdi@mhd1.moorhead.msus.edu) that made these changes:
|
|
* - increased MAX_LEN to 2048
|
|
* - added 'infobox', equivalent to a message box without pausing
|
|
* - added option '--clear' that will clear the screen
|
|
* - Explicit line breaking when printing prompt text can be
|
|
* invoked by real newline '\n' besides the string "\n"
|
|
* - an optional parameter '--title <string>' can be used to
|
|
* specify a title string for the dialog box
|
|
*
|
|
* 03/01/94 - added 'textbox', a dialog box for displaying text from a file.
|
|
* - Version 0.2 released.
|
|
*
|
|
* 04/01/94 - some fixes and improvements for 'textbox':
|
|
* - fixed a bug that will cause a segmentation violation when a
|
|
* line is longer than MAX_LEN characters. Lines will now be
|
|
* truncated if they are longer than MAX_LEN characters.
|
|
* - removed wrefresh() from print_line(). This will increase
|
|
* efficiency of print_page() which calls print_line().
|
|
* - display current position in the form of percentage into file.
|
|
* - Version 0.21 released.
|
|
*
|
|
* 05/01/94 - some changes for faster screen update.
|
|
*
|
|
* 07/01/94 - much more flexible color settings. Can use all 16 colors
|
|
* (8 normal, 8 highlight) of the Linux console.
|
|
*
|
|
* 08/01/94 - added run-time configuration using configuration file.
|
|
*
|
|
* 09/01/94 - some minor bug fixes and cleanups for menubox, checklist and
|
|
* textbox.
|
|
*
|
|
* 11/01/94 - added a man page.
|
|
*
|
|
* 13/01/94 - some changes for easier porting to other Unix systems (tested
|
|
* on Ultrix, SunOS and HPUX)
|
|
* - Version 0.3 released.
|
|
*
|
|
* 08/06/94 - Patches by Stuart Herbert - S.Herbert@shef.ac.uk
|
|
* Fixed attr_clear and the textbox stuff to work with ncurses 1.8.5
|
|
* Fixed the wordwrap routine - it'll actually wrap properly now
|
|
* Added a more 3D look to everything - having your own rc file could
|
|
* prove 'interesting' to say the least :-)
|
|
* Added radiolist option
|
|
* - Version 0.4 released.
