This is the latest version of manpage.sty. It is basically the same as the one I put on the net last week, but the code is much cleaner and I added the parameter auto indentation feature (see the comments bellow). The \dq macro is removed (use \" instead). I hope I won't update manpage.sty as frequent again. Enjoy. A copy of this file and cprog.sty will be at clarkson archives soon. -Rong Chen --------------------------- manpage.sty ------------------------------ % MANPAGE DOCUMENT STYLE -- Created 25 May 1990, Updated 25 November 1990 % manpage.sty % Rong Chen (rchen@cs.uiuc.edu) % Department of Computer Science % University of Illinois at Urbana-Champaign % Urbana, IL 61801 % Copyright (c) 1990 by Rong Chen % Permission to copy all or part of this work is granted, provided % that the copies are not made or distributed for resale, and that % the copyright notice and this notice are retained. % % THIS WORK IS PROVIDED ON AN "AS IS" BASIS.

The powerful features of object-oriented programming support the concepts that make computer problem solving a more human-like activity and that increase the re-usability of software code. As object-oriented languages are steadily available, object-oriented programming becomes more and more popular among both system developers and application programmers. C++ is a hybrid language that fuses object-oriented functionality with the features of a traditional and efficient structured language, C. C++ provides programmers and problem solvers object-oriented capability without loss of run-time or memory efficiency. In addition, C++ is available in almost every computer systems from PC to mainframe. \newpage \raggedbottom \pagenumbering{arabic} \pagestyle{headings} \chapter*{Class Descriptions} \begin{manpage}{OIM C++ Library}{Choice}{Version 1.0} \subtitle{Name} Choice --- a set of boxes representing the choices available. \subtitle{Declaration} \#include \<choice.h\> \function{Choice(Point origin, Point corner, int foreground_color, int background_color, int frame_style, int space_in_between, int number_of_choices, const~char\* first_label, $...$ )} Constructs a choice object. Each choice object is a set of boxes representing the choices available. "Origin" and "corner" define the rectangular area inside which the boxes are displayed. The "space_in_between" (in pixels) defines the distance between two adjacent boxes. Depending on whether there is enough room to put all the choices horizontally or vertically in the designated area, the choices will be laid out accordingly. The attributes "foreground_color", "background_color" and "frame_style" define the colors for each box that represents each choice. The number of labels starting with "first_label" must match the number given by "number_of_choices". Each label is displayed within its corresponding box. The choices are displayed as soon as they are created. \function{Choice(int number_of_choices, Boolean is_horizontal = VERTICAL)} Constructs an array of choices or a choice object with boxes of different sizes. The attributes of the actual choices will be defined later using the addItem() operation. Note: It is forbidden to have arguments in the constructors of array objects in C++. \function{\~Choice()} Choice class has an empty destructor. \subtitle{Description} A Choice object is a set of related boxes. It is used to display multiple choices on the screen. A choice may either be selected by pressing a hot key (when mouse is not enabled) or by pressing a mouse button when the mouse cursor is within the intended choice box. The first highlighted character in the text label will be the hot key if the mouse is not enabled, otherwise, the highlighted character will have no effect. For example, label "@N@ext" designates "N" as the hot key for the button if the mouse is not enabled. By default, if the mouse driver is loaded before program execution, the mouse is enabled. When using the mouse to select a choice, the selection is immediate; a hot key must be confirmed by pressing ENTER (carriage return key). Arrow keys can also be used to move the current selection in the direction indicated by the arrows, this also requires an ENTER to confirm. \subtitle{Global \\ Variables} \variable{char host_name[20] = \"rose.cs.uiuc.edu\"} The "host_name" buffer is initialized to the current machine name before the main() function is executed. The machine name is usually declared in a DOS shell variable "OIMUSER". \variable{Boolean mouse_installed} By default, the "mouse_installed" variable is assigned to TRUE if the mouse driver has been installed before program execution; otherwise it is assigned to FALSE. The value may also be changed through enableMouse() and disableMouse() functions. \subtitle{Macros} \function{MAX({\it x}, {\it y})} Returns the maximum of the two comparable objects "x", and "y". This macro is often used to compare integers or real numbers. \function{MIN({\it x}, {\it y})} Returns the minimum of the two comparable objects "x", and "y". This macro is often used to compare integers or real numbers. \subtitle{Public \\ Operations} \function{void addItem(Point origin, Point corner, int foreground_color, int background_color, int frame_style, const~char\* label, int text_color = WHITE, int text_highlight_color = LIGHT_WHITE)} Defines the attributes of a choice box in the array declared by the Choice(int "number_of_choices", Boolean "is_horizontal" = VERTICAL) constructor. It must be called exactly "number_of_choices" times. The first call specifies the first choice, second call specifies the second choice, and so on. The attributes "origin" and "corner" define a box area where the choice item is located on the screen. Other attributes are self-explanatory. This call is particularly useful on program setup pages. \function{Boolean hasValue()} Returns TRUE if the designated choice object has been selected at least once. Graphically, it means one of the choices is rendered in reverse colors. It is sometimes necessary to check if all choice objects on a screen have been selected, so that a program can go on to the next page of screen. If a previous select() call is returned abnormally by pressing an ESC key, this function will return FALSE. Should this occur, the previous value, if any, will also be lost. \subtitle{Virtual \\ Operations} \function{void action(int status)} Defines the behaviors of the choice object when a choice handler has been bonded to the object. This function is called by the event handler when it detects that the choice object has been selected. The default action is to do nothing if no choice handler presents, otherwise, it invokes the choice handler and passes it along with the current status (whatever has been returned from a status() call). Do not modify this function unless it is absolutely necessary because it redefines the semantics of all choice objects. \function{void bind(void \hbox{\rm (\*{\it handler})(int)})} Associates a choice handler function with the choice object. Every time this choice object is invoked, the choice handler is called immediately. The handler is passed along with the current "status" (return value of status() call) as its argument. The default action taken by the event handler can be modified by changing the next function action(). \function{Boolean isSelected(Point cursor)} Returns TRUE if a legal hot key is pressed for the the indicated choice object. It also returns TRUE if a mouse button is pressed within the range of the choice object area. This call is used by the event handler to check if this choice object has been selected. It is hardly needed in regular applications. The "cursor" is for mouse cursor in mouse mode or faked with the current keyboard input as the cursor's x coordinate. \subtitle{See Also} Event, Button, Box \subtitle{Author} Ron Chen at the Office for Information Management, UIUC. 9-1-89. \end{manpage} \newpage \begin{verbatim} /* EXAMPLE 2 */ #include <stdlib.h> #include "choice.h" void handler1(int pick) { Box box(500, 30, 600, 60, LIGHT_CYAN, LIGHT_MAGENTA); box << pick + 1; } void handler2(int pick) { Box box(500, 30, 600, 60, LIGHT_CYAN, LIGHT_MAGENTA); box << (pick==0 ?
