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 + * Added backtitle option + * - Version 0.4 released. + * + * 10/10/94 - Patches by Marc Ewing - marc@redhat.com + * Added --separate-output + * Added init val to inputbox + * Added guage widget + */ + + +#define __DIALOG_MAIN__ + + +#include "dialog.h" +#ifdef HAVE_NCURSES +#include "colors.h" +#endif + +static char *backtitle = NULL;
