-Introduction</a></h2>
-<p>In the olden days of teletype terminals, terminals were away
-from computers and were connected to them through serial cables.
-The terminals could be configured by sending a series of bytes. All
-the capabilities (such as moving the cursor to a new location,
-erasing part of the screen, scrolling the screen, changing modes
-etc.) of terminals could be accessed through these series of bytes.
-These control seeuqnces are usually called escape sequences,
-because they start with an escape(0x1B) character. Even today, with
-proper emulation, we can send escape sequences to the emulator and
-achieve the same effect on a terminal window.</p>
-<p>Suppose you wanted to print a line in color. Try typing this on
-your console.</p>
-<table border="0" bgcolor="#E0E0E0" width="100%">
-<tr>
-<td>
-<pre class="PROGRAMLISTING">
-<font color="#000000">echo "^[[0;31;40mIn Color"</font>
-</pre></td>
-</tr>
-</table>
-<p>The first character is an escape character, which looks like two
-characters ^ and [. To be able to print it, you have to press
-CTRL+V and then the ESC key. All the others are normal printable
-characters. You should be able to see the string "In Color" in red.
-It stays that way and to revert back to the original mode type
-this.</p>
-<table border="0" bgcolor="#E0E0E0" width="100%">
-<tr>
-<td>
-<pre class="PROGRAMLISTING">
-<font color="#000000">echo "^[[0;37;40m"</font>
-</pre></td>
-</tr>
-</table>
-<p>Now, what do these magic characters mean? Difficult to
-comprehend? They might even be different for different terminals.
-So the designers of UNIX invented a mechanism named <var class=
-"LITERAL">termcap</var>. It is a file that lists all the
-capabilities of a particular terminal, along with the escape
-sequences needed to achieve a particular effect. In the later
-years, this was replaced by <var class="LITERAL">terminfo</var>.
-Without delving too much into details, this mechanism allows
-application programs to query the terminfo database and obtain the
-control characters to be sent to a terminal or terminal
-emulator.</p>
-<div class="SECT2">
-<hr>
-<h3 class="SECT2"><a name="WHATIS" id="WHATIS">1.1. What is
-NCURSES?</a></h3>
-<p>You might be wondering, what the import of all this technical
-gibberish is. In the above scenario, every application program is
-supposed to query the terminfo and perform the necessary stuff
-(sending control characters etc.). It soon became difficult to
-manage this complexity and this gave birth to 'CURSES'. Curses is a
-pun on the name "cursor optimization". The Curses library forms a
-wrapper over working with raw terminal codes, and provides highly
-flexible and efficient API (Application Programming Interface). It
-provides functions to move the cursor, create windows, produce
-colors, play with mouse etc. The application programs need not
-worry about the underlying terminal capabilities.</p>
-<p>So what is NCURSES? NCURSES is a clone of the original System V
-Release 4.0 (SVr4) curses. It is a freely distributable library,
-fully compatible with older version of curses. In short, it is a
-library of functions that manages an application's display on
-character-cell terminals. In the remainder of the document, the
-terms curses and ncurses are used interchangeably.</p>
-<p>A detailed history of NCURSES can be found in the NEWS file from
-the source distribution. The current package is maintained by
-<a href="mailto:dickey@his.com" target="_top">Thomas Dickey</a>.
-You can contact the maintainers at <a href=
-"mailto:bug-ncurses@gnu.org" target=
-"_top">bug-ncurses@gnu.org</a>.</p>
-</div>
-<div class="SECT2">
-<hr>
-<h3 class="SECT2"><a name="WHATCANWEDO" id="WHATCANWEDO">1.2. What
-we can do with NCURSES</a></h3>
-<p>NCURSES not only creates a wrapper over terminal capabilities,
-but also gives a robust framework to create nice looking UI (User
-Interface)s in text mode. It provides functions to create windows
-etc. Its sister libraries panel, menu and form provide an extension
-to the basic curses library. These libraries usually come along
-with curses. One can create applications that contain multiple
-windows, menus, panels and forms. Windows can be managed
-independently, can provide 'scrollability' and even can be
-hidden.</p>
-<p>Menus provide the user with an easy command selection option.
-Forms allow the creation of easy-to-use data entry and display
-windows. Panels extend the capabilities of ncurses to deal with
-overlapping and stacked windows.</p>
-<p>These are just some of the basic things we can do with ncurses.
-As we move along, We will see all the capabilities of these
-libraries.</p>

-<h3 class="SECT2"><a name="WHERETOGETIT" id="WHERETOGETIT">1.3.
-Where to get it</a></h3>
-<p>All right, now that you know what you can do with ncurses, you
-must be rearing to get started. NCURSES is usually shipped with
-your installation. In case you don't have the library or want to
-compile it on your own, read on.</p>
-<p><em>Compiling the package</em></p>
-<p>NCURSES can be obtained from <a href=
-"ftp://ftp.gnu.org/pub/gnu/ncurses/ncurses.tar.gz" target=
-"_top">ftp://ftp.gnu.org/pub/gnu/ncurses/ncurses.tar.gz</a> or any
-of the ftp sites mentioned in <a href=
-"http://www.gnu.org/order/ftp.html" target=
-"_top">http://www.gnu.org/order/ftp.html</a>.</p>
-<p>Read the README and INSTALL files for details on to how to
-install it. It usually involves the following operations.</p>

+><P
+>In the olden days of teletype terminals, terminals were away from computers and
+were connected to them through serial cables. The terminals could be configured
+by sending a series of bytes. All the capabilities (such as 
+moving the cursor to a new location, erasing part of the screen, scrolling the 
+screen, changing modes etc.) of terminals could be accessed through these 
+series of bytes. These control seeuqnces are usually called escape sequences, 
+because they start 
+with an escape(0x1B) character. Even today, with proper emulation, we can send 
+escape sequences to the emulator and achieve the same effect on a terminal 
+window.</P
+><P
+>Suppose you wanted to print a line in color. Try typing this on your console.</P
+><PRE
+CLASS="PROGRAMLISTING"
+>echo "^[[0;31;40mIn Color"</PRE
+><P
+>The first character is an escape character, which looks like two characters ^ 
+and [. To be able to print it, you have to press CTRL+V and then the ESC key. 
+All the others are normal printable characters. You should be able to see the 
+string "In Color" in red. It stays that way and to revert back to the original 
+mode type this.</P
+><PRE
+CLASS="PROGRAMLISTING"
+>echo "^[[0;37;40m"</PRE
+><P
+>Now, what do these magic characters mean? Difficult to comprehend? They might
+even be different for different terminals. So the designers of UNIX invented a 
+mechanism named <TT
+CLASS="LITERAL"
+>termcap</TT
+>. It is a file that
+lists all the capabilities of a particular terminal, along with the escape
+sequences needed to achieve a particular effect. In the later years, this was 
+replaced by <TT
+CLASS="LITERAL"
+>terminfo</TT
+>. Without delving too 
+much into details, this mechanism allows application 
+programs to query the terminfo database and obtain the control characters to be 
+sent to a terminal or terminal emulator.</P

+>1.1. What is NCURSES?</A
+></H3
+><P
+> 
+You might be wondering, what the import of all this technical gibberish is.  In
+the above scenario, every application program is supposed to query the terminfo
+and perform the necessary stuff (sending control characters etc.).  It soon became
+difficult to manage this complexity and this gave birth to 'CURSES'.  Curses is
+a pun on the name "cursor optimization". The Curses library forms a wrapper
+over working with raw terminal codes, and provides highly flexible and
+efficient API (Application Programming Interface). It provides functions to
+move the cursor, create windows, produce colors, play with mouse etc.  The
+application programs need not worry about the underlying terminal capabilities.</P
+><P
+>So what is NCURSES? NCURSES is a clone of the original System V Release 4.0
+(SVr4) curses. It is a freely distributable library, fully compatible with
+older version of curses.  In short, it is a library of functions that manages
+an application's display on character-cell terminals.  In the remainder of the
+document, the terms curses and ncurses are used interchangeably.  </P
+><P
+>A detailed history of NCURSES can be found in the NEWS file from the source
+distribution. The current package is maintained by

+><P
+>NCURSES not only creates a wrapper over terminal capabilities, but also gives a
+robust framework to create nice looking UI (User Interface)s in text mode.  It
+provides functions to create windows etc.  Its sister libraries panel, menu and
+form provide an extension to the basic curses library. These libraries usually
+come along with curses. One can create applications that contain multiple
+windows, menus, panels and forms. Windows can be managed independently, can
+provide 'scrollability' and even can be hidden.</P
+><P
+> 
+Menus provide the user with an easy command selection option.  Forms allow the
+creation of easy-to-use data entry and display windows.  Panels extend the
+capabilities of ncurses to deal with overlapping and stacked windows.</P
+><P
+>These are just some of the basic things we can do with ncurses. As we move
+along, We will see all the capabilities of these libraries. </P

-About initscr()</a></h4>
-<p>The function initscr() initializes the terminal in curses mode.
-In some implementations, it clears the screen and presents a blank
-screen. To do any screen manipulation using curses package this has
-to be called first. This function initializes the curses system and
-allocates memory for our present window (called <var class=
-"LITERAL">stdscr</var>) and some other data-structures. Under
-extreme cases this function might fail due to insufficient memory
-to allocate memory for curses library's data structures.</p>
-<p>After this is done, we can do a variety of initializations to
-customize our curses settings. These details will be explained
-<a href="#INIT">later</a> .</p>

-<div class="SECT3">
-<hr>
-<h4 class="SECT3"><a name="MYST-REFRESH" id="MYST-REFRESH">2.2.2.
-The mysterious refresh()</a></h4>
-<p>The next line printw prints the string "Hello World !!!" on to
-the screen. This function is analogous to normal printf in all
-respects except that it prints the data on a window called stdscr
-at the current (y,x) co-ordinates. Since our present co-ordinates
-are at 0,0 the string is printed at the left hand corner of the
-window.</p>
-<p>This brings us to that mysterious refresh(). Well, when we
-called printw the data is actually written to an imaginary window,
-which is not updated on the screen yet. The job of printw is to
-update a few flags and data structures and write the data to a
-buffer corresponding to stdscr. In order to show it on the screen,
-we need to call refresh() and tell the curses system to dump the
-contents on the screen.</p>
-<p>The philosophy behind all this is to allow the programmer to do
-multiple updates on the imaginary screen or windows and do a
-refresh once all his screen update is done. refresh() checks the
-window and updates only the portion which has been changed. This
-improves performance and offers greater flexibility too. But, it is
-sometimes frustrating to beginners. A common mistake committed by
-beginners is to forget to call refresh() after they did some update
-through printw() class of functions. I still forget to add it
-sometimes :-)</p>

-<h4 class="SECT3"><a name="ABOUT-ENDWIN" id="ABOUT-ENDWIN">2.2.3.
-About endwin()</a></h4>
-<p>And finally don't forget to end the curses mode. Otherwise your
-terminal might behave strangely after the program quits. endwin()
-frees the memory taken by curses sub-system and its data structures
-and puts the terminal in normal mode. This function must be called
-after you are done with the curses mode.</p>

-<p>Now that we have seen how to write a simple curses program let's
-get into the details. There are many functions that help customize
-what you see on screen and many features which can be put to full

-Initialization</a></h2>
-<p>We now know that to initialize curses system the function
-initscr() has to be called. There are functions which can be called
-after this initialization to customize our curses session. We may
-ask the curses system to set the terminal in raw mode or initialize
-color or initialize the mouse etc.. Let's discuss some of the
-functions that are normally called immediately after initscr();</p>
-<div class="SECT2">

-</div>
-<div class="SECT2">
-<hr>
-<h3 class="SECT2"><a name="RAWCBREAK" id="RAWCBREAK">4.2. raw() and
-cbreak()</a></h3>
-<p>Normally the terminal driver buffers the characters a user types
-until a new line or carriage return is encountered. But most
-programs require that the characters be available as soon as the
-user types them. The above two functions are used to disable line
-buffering. The difference between these two functions is in the way
-control characters like suspend (CTRL-Z), interrupt and quit
-(CTRL-C) are passed to the program. In the raw() mode these
-characters are directly passed to the program without generating a
-signal. In the <var class="LITERAL">cbreak()</var> mode these
-control characters are interpreted as any other character by the
-terminal driver. I personally prefer to use raw() as I can exercise
-greater control over what the user does.</p>
-</div>
-<div class="SECT2">
-<hr>
-<h3 class="SECT2"><a name="ECHONOECHO" id="ECHONOECHO">4.3. echo()
-and noecho()</a></h3>
-<p>These functions control the echoing of characters typed by the
-user to the terminal. <var class="LITERAL">noecho()</var> switches
-off echoing. The reason you might want to do this is to gain more
-control over echoing or to suppress unnecessary echoing while
-taking input from the user through the getch() etc. functions. Most
-of the interactive programs call <var class=
-"LITERAL">noecho()</var> at initialization and do the echoing of
-characters in a controlled manner. It gives the programmer the
-flexibility of echoing characters at any place in the window
-without updating current (y,x) co-ordinates.</p>
-</div>
-<div class="SECT2">
-<hr>
-<h3 class="SECT2"><a name="KEYPAD" id="KEYPAD">4.4.
-keypad()</a></h3>
-<p>This is my favorite initialization function. It enables the
-reading of function keys like F1, F2, arrow keys etc. Almost every
-interactive program enables this, as arrow keys are a major part of
-any User Interface. Do <var class="LITERAL">keypad(stdscr,
-TRUE)</var> to enable this feature for the regular screen (stdscr).
-You will learn more about key management in later sections of this
-document.</p>

-<div class="SECT2">
-<hr>
-<h3 class="SECT2"><a name="HALFDELAY" id="HALFDELAY">4.5.
-halfdelay()</a></h3>
-<p>This function, though not used very often, is a useful one at
-times. halfdelay()is called to enable the half-delay mode, which is
-similar to the cbreak() mode in that characters typed are
-immediately available to program. However, it waits for 'X' tenths
-of a second for input and then returns ERR, if no input is
-available. 'X' is the timeout value passed to the function
-halfdelay(). This function is useful when you want to ask the user
-for input, and if he doesn't respond with in certain time, we can
-do some thing else. One possible example is a timeout at the
-password prompt.</p>

-<p>I guess you can't wait any more to see some action. Back to our

-<ol type="1">

-<p>addch() class: Print single character with attributes</p>

-<p>These functions put a single character into the current cursor
-location and advance the position of the cursor. You can give the
-character to be printed but they usually are used to print a
-character with some attributes. Attributes are explained in detail
-in later <a href="#ATTRIB">sections</a> of the document. If a
-character is associated with an attribute(bold, reverse video
-etc.), when curses prints the character, it is printed in that
-attribute.</p>
-<p>In order to combine a character with some attributes, you have
-two options:</p>
-<ul>
-<li>
-<p>By OR'ing a single character with the desired attribute macros.
-These attribute macros could be found in the header file
-<var class="LITERAL">ncurses.h</var>. For example, you want to

-function must used so that characters are immediately available to
-your program. Another widely used function is noecho(). As the name

-<p>Windows form the most important concept in curses. You have seen

-windows is to manipulate parts of the screen separately, for better
-efficiency, by updating only the windows that need to be changed
-and for a better design. I would say the last reason is the most

-just an abstraction of an imaginary window, which can be
-manipulated independent of other parts of screen. The function

-<p>No GUI is complete without a strong user interface and to
-interact with the user, a curses program should be sensitive to key
-presses or the mouse actions done by the user. Let's deal with the
-keys first.</p>
-<p>As you have seen in almost all of the above examples, it's very
-easy to get key input from the user. A simple way of getting key
-presses is to use <var class="LITERAL">getch()</var> function. The
-cbreak mode should be enabled to read keys when you are interested
-in reading individual key hits rather than complete lines of text
-(which usually end with a carriage return). keypad should be
-enabled to get the Functions keys, arrow keys etc. See the
-initialization section for details.</p>
-<p><var class="LITERAL">getch()</var> returns an integer
-corresponding to the key pressed. If it is a normal character, the
-integer value will be equivalent to the character. Otherwise it
-returns a number which can be matched with the constants defined in
-<var class="LITERAL">curses.h</var>. For example if the user

-<p>Panel object is a window that is implicitly treated as part of a
-deck including all other panel objects. The deck is treated as a
-stack with the top panel being completely visible and the other
-panels may or may not be obscured according to their positions. So
-the basic idea is to create a stack of overlapping panels and use
-panels library to display them correctly. There is a function
-similar to refresh() which, when called , displays panels in the
-correct order. Functions are provided to hide or show panels, move
-panels, change its size etc.. The overlapping problem is managed by
-the panels library during all the calls to these functions.</p>
-<p>The general flow of a panel program goes like this:</p>
-<ol type="1">
-<li>
-<p>Create the windows (with newwin()) to be attached to the
-panels.</p>
-</li>
-<li>
-<p>Create panels with the chosen visibility order. Stack them up
-according to the desired visibility. The function new_panel() is
-used to created panels.</p>
-</li>
-<li>
-<p>Call update_panels() to write the panels to the virtual screen
-in correct visibility order. Do a doupdate() to show it on the
-screen.</p>
-</li>
-<li>
-<p>Mainpulate the panels with show_panel(), hide_panel(),
-move_panel() etc. Make use of helper functions like panel_hidden()
-and panel_window(). Make use of user pointer to store custom data
-for a panel. Use the functions set_panel_userptr() and
-panel_userptr() to set and get the user pointer for a panel.</p>
-</li>
-<li>
-<p>When you are done with the panel use del_panel() to delete the
-panel.</p>
-</li>
-</ol>
-<p>Let's make the concepts clear, with some programs. The following
-is a simple program which creates 3 overlapping panels and shows
-them on the screen.</p>

-Using User Pointers</a></h3>
-<p>In the above example I used user pointers to find out the next
-window in the cycle. We can attach custom information to the panel
-by specifying a user pointer, which can point to any information
-you want to store. In this case I stored the pointer to the next
-panel in the cycle. User pointer for a panel can be set with the
-function <var class="LITERAL">set_panel_userptr()</var>. It can be
-accessed using the function <var class=
-"LITERAL">panel_userptr()</var> which will return the user pointer
-for the panel given as argument. After finding the next panel in
-the cycle It's brought to the top by the function top_panel(). This
-function brings the panel given as argument to the top of the panel
-stack.</p>

-<p>The function <var class="LITERAL">move_panel()</var> can be used
-to move a panel to the desired location. It does not change the
-position of the panel in the stack. Make sure that you use
-move_panel() instead mvwin() on the window associated with the
-panel.</p>
-<p>Resizing a panel is slightly complex. There is no straight
-forward function just to resize the window associated with a panel.
-A solution to resize a panel is to create a new window with the
-desired sizes, change the window associated with the panel using
-replace_panel(). Don't forget to delete the old window. The window
-associated with a panel can be found by using the function
-panel_window().</p>
-<p>The following program shows these concepts, in supposedly simple
-program. You can cycle through the window with &lt;TAB&gt; as
-usual. To resize or move the active panel press 'r' for resize 'm'
-for moving. Then use arrow keys to resize or move it to the desired
-way and press enter to end your resizing or moving. This example

+>In the above example I used user pointers to find out the next window in the
+cycle.  We can attach custom information to the panel by specifying a user
+pointer, which can point to any information you want to store. In this case I
+stored the pointer to the next panel in the cycle. User pointer for a panel can
+be set with the function <TT
+CLASS="LITERAL"
+> set_panel_userptr()</TT
+>.
+It can be accessed using the function <TT
+CLASS="LITERAL"
+>panel_userptr()</TT
+> which will return the user pointer for the panel given as
+argument. After finding the next panel in the cycle It's brought to the top by
+the function top_panel().  This function brings the panel given as argument to
+the top of the panel stack.  </P

+><P
+>The function <TT
+CLASS="LITERAL"
+>move_panel()</TT
+> can be used to move a
+panel to the desired location. It does not change the position of the panel in
+the stack. Make sure that you use move_panel() instead mvwin() on the window
+associated with the panel.</P
+><P
+>Resizing a panel is slightly complex.  There is no straight forward function
+just to resize the window associated with a panel. A solution to resize a panel
+is to create a new window with the desired sizes, change the window associated
+with the panel using replace_panel(). Don't forget to delete the old window. The
+window associated with a panel can be found by using the function
+panel_window().</P
+><P
+>The following program shows these concepts, in supposedly simple program. You
+can cycle through the window with &lt;TAB&gt; as usual. To resize or move the
+active panel press 'r' for resize 'm' for moving. Then use arrow keys to resize
+or move it to the desired way and press enter to end your resizing or moving.
+This example makes use of user data to get the required data to do the

-<p>The menus library provides a nice extension to basic curses,
-through which you can create menus. It provides a set of functions
-to create menus. But they have to be customized to give a nicer
-look, with colors etc. Let's get into the details.</p>
-<p>A menu is a screen display that assists the user to choose some
-subset of a given set of items. To put it simple, a menu is a
-collection of items from which one or more items can be chosen.
-Some readers might not be aware of multiple item selection
-capability. Menu library provides functionality to write menus from
-which the user can chose more than one item as the preferred
-choice. This is dealt with in a later section. Now it is time for
-some rudiments.</p>

-<p>As you have seen in the above example, menu_driver plays an

-understand various options it takes and what they do. As explained

-Let's dissect the different navigational requests.</p>
-<ul>
-<li>
-<p><em>REQ_LEFT_ITEM and REQ_RIGHT_ITEM</em></p>
-<p>A Menu can be displayed with multiple columns for more than one
-item. This can be done by using the <var class=
-"LITERAL">menu_format()</var>function. When a multi columnar menu
-is displayed these requests cause the menu driver to move the
-current selection to left or right.</p>
-</li>
-<li>
-<p><em>REQ_UP_ITEM and REQ_DOWN_ITEM</em></p>
-<p>These two options you have seen in the above example. These
-options when given, makes the menu_driver to move the current
-selection to an item up or down.</p>
-</li>
-<li>
-<p><em>REQ_SCR_* options</em></p>
-<p>The four options REQ_SCR_ULINE, REQ_SCR_DLINE, REQ_SCR_DPAGE,
-REQ_SCR_UPAGE are related to scrolling. If all the items in the
-menu cannot be displayed in the menu sub window, then the menu is
-scrollable. These requests can be given to the menu_driver to do
-the scrolling either one line up, down or one page down or up
-respectively.</p>
-</li>
-<li>
-<p><em>REQ_FIRST_ITEM, REQ_LAST_ITEM, REQ_NEXT_ITEM and
-REQ_PREV_ITEM</em></p>
-<p>These requests are self explanatory.</p>
-</li>
-<li>
-<p><em>REQ_TOGGLE_ITEM</em></p>
-<p>This request when given, toggles the present selection. This
-option is to be used only in a multi valued menu. So to use this
-request the option O_ONEVALUE must be off. This option can be made
-off or on with set_menu_opts().</p>
-</li>
-<li>
-<p><em>Pattern Requests</em></p>
-<p>Every menu has an associated pattern buffer, which is used to
-find the nearest match to the ascii characters entered by the user.
-Whenever ascii characters are given to menu_driver, it puts in to
-the pattern buffer. It also tries to find the nearest match to the
-pattern in the items list and moves current selection to that item.
-The request REQ_CLEAR_PATTERN clears the pattern buffer. The
-request REQ_BACK_PATTERN deletes the previous character in the
-pattern buffer. In case the pattern matches more than one item then
-the matched items can be cycled through REQ_NEXT_MATCH and
-REQ_PREV_MATCH which move the current selection to the next and
-previous matches respectively.</p>
-</li>
-<li>
-<p><em>Mouse Requests</em></p>
-<p>In case of KEY_MOUSE requests, according to the mouse position
-an action is taken accordingly. The action to be taken is explained

-<p>Whew, A lot of new functions. Let's take them one after another.
-Firstly, the REQ_TOGGLE_ITEM. In a multi-valued menu, the user
-should be allowed to select or un select more than one item. The
-request REQ_TOGGLE_ITEM toggles the present selection. In this case
-when space is pressed REQ_TOGGLE_ITEM request is sent to
-menu_driver to achieve the result.</p>
-<p>Now when the user presses &lt;ENTER&gt; we show the items he
-presently selected. First we find out the items associated with the
-menu using the function menu_items(). Then we loop through the
-items to find out if the item is selected or not. The function
-item_value() returns TRUE if an item is selected. The function
-item_count() returns the number of items in the menu. The item name
-can be found with item_name(). You can also find the description
-associated with an item using item_description().</p>

-<p>Well, by this time you must be itching for some difference in

-You want to create nice menus similar to those text mode <a href=
-"http://www.jersey.net/~debinjoe/games/" target="_top">dos
-games</a>. The functions set_menu_fore() and set_menu_back() can be
-used to change the attribute of the selected item and unselected
-item. The names are misleading. They don't change menu's foreground
-or background which would have been useless.</p>
-<p>The function set_menu_grey() can be used to set the display
-attribute for the non-selectable items in the menu. This brings us
-to the interesting option for an item the one and only
-O_SELECTABLE. We can turn it off by the function item_opts_off()
-and after that that item is not selectable. It's like a grayed item
-in those fancy windows menus. Let's put these concepts in practice
-with this example</p>

+menus similar to those text mode <A

+>. The functions
+set_menu_fore() and set_menu_back() can be used to change the attribute of the
+selected item and unselected item. The names are misleading. They don't change
+menu's foreground or background which would have been useless. </P
+><P
+>The function set_menu_grey() can be used to set the display attribute for the
+non-selectable items in the menu. This brings us to the interesting option for
+an item the one and only O_SELECTABLE. We can turn it off by the function
+item_opts_off() and after that that item is not selectable. It's like a grayed
+item in those fancy windows menus. Let's put these concepts in practice with
+this example</P

-quite difficult to write those nifty forms in plain ncurses. Forms

-<p>Forms are created in much the same way as menus. First the
-fields related to the form are created with new_field(). You can
-set options for the fields, so that they can be displayed with some
-fancy attributes, validated before the field looses focus etc..
-Then the fields are attached to form. After this, the form can be
-posted to display and is ready to receive inputs. On the similar
-lines to menu_driver(), the form is manipulated with form_driver().
-We can send requests to form_driver to move focus to a certain
-field, move cursor to end of the field etc.. After the user enters
-values in the fields and validation done, form can be unposted and
-memory allocated can be freed.</p>
-<p>The general flow of control of a forms program looks like
-this.</p>
-<ol type="1">
-<li>
-<p>Initialize curses</p>
-</li>
-<li>
-<p>Create fields using new_field(). You can specify the height and

-<dd>
-<p>Controls whether data is displayed during field entry. If this

-field cursor will not move. You can turn off the O_PUBLIC bit to
-define password fields.</p>
-</dd>
-<dt>O_EDIT</dt>
-<dd>
-<p>Controls whether the field's data can be modified. When this
-option is off, all editing requests except <var class=
-"LITERAL">REQ_PREV_CHOICE</var> and <var class=
-"LITERAL">REQ_NEXT_CHOICE</var>will fail. Such read-only fields may
-be useful for help messages.</p>
-</dd>
-<dt>O_WRAP</dt>
-<dd>
-<p>Controls word-wrapping in multi-line fields. Normally, when any
-character of a (blank-separated) word reaches the end of the
-current line, the entire word is wrapped to the next line (assuming
-there is one). When this option is off, the word will be split
-across the line break.</p>

-<dt>O_BLANK</dt>
-<dd>
-<p>Controls field blanking. When this option is on, entering a
-character at the first field position erases the entire field
-(except for the just-entered character).</p>
-</dd>
-<dt>O_AUTOSKIP</dt>
-<dd>
-<p>Controls automatic skip to next field when this one fills.
-Normally, when the forms user tries to type more data into a field
-than will fit, the editing location jumps to next field. When this
-option is off, the user's cursor will hang at the end of the field.
-This option is ignored in dynamic fields that have not reached
-their size limit.</p>
-</dd>
-<dt>O_NULLOK</dt>
-<dd>
-<p>Controls whether validation is applied to blank fields.
-Normally, it is not; the user can leave a field blank without
-invoking the usual validation check on exit. If this option is off
-on a field, exit from it will invoke a validation check.</p>
-</dd>
-<dt>O_PASSOK</dt>
-<dd>
-<p>Controls whether validation occurs on every exit, or only after

-change during forms processing.</p>
-</dd>
-<dt>O_STATIC</dt>

-<p>Recall the library routine new_field; a new field created with

-<p>The above two paragraphs pretty much describe a dynamically
-growable field's behavior. The way other parts of forms library
-behaves is described below:</p>
-<ol type="1">
-<li>
-<p>The field option O_AUTOSKIP will be ignored if the option
-O_STATIC is off and there is no maximum growth specified for the
-field. Currently, O_AUTOSKIP generates an automatic REQ_NEXT_FIELD
-form driver request when the user types in the last character
-position of a field. On a growable field with no maximum growth
-specified, there is no last character position. If a maximum growth
-is specified, the O_AUTOSKIP option will work as normal if the
-field has grown to its maximum size.</p>
-</li>
-<li>
-<p>The field justification will be ignored if the option O_STATIC
-is off. Currently, set_field_just can be used to JUSTIFY_LEFT,
-JUSTIFY_RIGHT, JUSTIFY_CENTER the contents of a one line field. A
-growable one line field will, by definition, grow and scroll
-horizontally and may contain more data than can be justified. The
-return from field_just will be unchanged.</p>
-</li>
-<li>
-<p>The overloaded form driver request REQ_NEW_LINE will operate the
-same way regardless of the O_NL_OVERLOAD form option if the field
-option O_STATIC is off and there is no maximum growth specified for
-the field. Currently, if the form option O_NL_OVERLOAD is on,
-REQ_NEW_LINE implicitly generates a REQ_NEXT_FIELD if called from
-the last line of a field. If a field can grow without bound, there
-is no last line, so REQ_NEW_LINE will never implicitly generate a
-REQ_NEXT_FIELD. If a maximum growth limit is specified and the
-O_NL_OVERLOAD form option is on, REQ_NEW_LINE will only implicitly
-generate REQ_NEXT_FIELD if the field has grown to its maximum size
-and the user is on the last line.</p>
-</li>
-<li>
-<p>The library call dup_field will work as usual; it will duplicate
-the field, including the current buffer size and contents of the
-field being duplicated. Any specified maximum growth will also be
-duplicated.</p>
-</li>
-<li>
-<p>The library call link_field will work as usual; it will
-duplicate all field attributes and share buffers with the field
-being linked. If the O_STATIC field option is subsequently changed
-by a field sharing buffers, how the system reacts to an attempt to
-enter more data into the field than the buffer will currently hold
-will depend on the setting of the option in the current field.</p>
-</li>
-<li>
-<p>The library call field_info will work as usual; the variable
-nrow will contain the value of the original call to new_field. The
-user should use dynamic_field_info, described above, to query the
-current size of the buffer.</p>

-<p>These requests treat the list of fields on a page as cyclic;
-that is, REQ_NEXT_FIELD from the last field goes to the first, and
-REQ_PREV_FIELD from the first field goes to the last. The order of
-the fields for these (and the REQ_FIRST_FIELD and REQ_LAST_FIELD
-requests) is simply the order of the field pointers in the form
-array (as set up by new_form() or set_form_fields()</p>
-<p>It is also possible to traverse the fields as if they had been
-sorted in screen-position order, so the sequence goes left-to-right
-and top-to-bottom. To do this, use the second group of four
-sorted-movement requests.</p>
-<p>Finally, it is possible to move between fields using visual
-directions up, down, right, and left. To accomplish this, use the
-third group of four requests. Note, however, that the position of a
-form for purposes of these requests is its upper-left corner.</p>
-<p>For example, suppose you have a multi-line field B, and two
-single-line fields A and C on the same line with B, with A to the
-left of B and C to the right of B. A REQ_MOVE_RIGHT from A will go
-to B only if A, B, and C all share the same first line; otherwise

-<p>The behavior of the REQ_NEW_LINE and REQ_DEL_PREV requests is
-complicated and partly controlled by a pair of forms options. The
-special cases are triggered when the cursor is at the beginning of
-a field, or on the last line of the field.</p>
-<p>First, we consider REQ_NEW_LINE:</p>
-<p>The normal behavior of REQ_NEW_LINE in insert mode is to break
-the current line at the position of the edit cursor, inserting the
-portion of the current line after the cursor as a new line
-following the current and moving the cursor to the beginning of
-that new line (you may think of this as inserting a newline in the
-field buffer).</p>
-<p>The normal behavior of REQ_NEW_LINE in overlay mode is to clear
-the current line from the position of the edit cursor to end of
-line. The cursor is then moved to the beginning of the next
-line.</p>
-<p>However, REQ_NEW_LINE at the beginning of a field, or on the
-last line of a field, instead does a REQ_NEXT_FIELD. O_NL_OVERLOAD
-option is off, this special action is disabled.</p>
-<p>Now, let us consider REQ_DEL_PREV:</p>
-<p>The normal behavior of REQ_DEL_PREV is to delete the previous
-character. If insert mode is on, and the cursor is at the start of
-a line, and the text on that line will fit on the previous one, it
-instead appends the contents of the current line to the previous
-one and deletes the current line (you may think of this as deleting
-a newline from the field buffer).</p>
-<p>However, REQ_DEL_PREV at the beginning of a field is instead
-treated as a REQ_PREV_FIELD.</p>
-<p>If the O_BS_OVERLOAD option is off, this special action is
-disabled and the forms driver just returns E_REQUEST_DENIED.</p>

-Requests</a></h4>
-<p>If the type of your field is ordered, and has associated
-functions for getting the next and previous values of the type from
-a given value, there are requests that can fetch that value into
-the field buffer:</p>
-<ul>
-<li>
-<p><em>REQ_NEXT_CHOICE</em> Place the successor value of the
-current value in the buffer.</p>
-</li>
-<li>
-<p><em>REQ_PREV_CHOICE</em> Place the predecessor value of the
-current value in the buffer.</p>
-</li>
-</ul>
-<p>Of the built-in field types, only TYPE_ENUM has built-in
-successor and predecessor functions. When you define a field type
-of your own (see Custom Validation Types), you can associate our
-own ordering functions.</p>

-<p>Form requests are represented as integers above the curses value
-greater than KEY_MAX and less than or equal to the constant
-MAX_COMMAND. A value within this range gets ignored by
-form_driver(). So this can be used for any purpose by the
-application. It can be treated as an application specific action

-<p><em>Linux is based on the Unix operating system, but also
-features a number of unique and useful kernel features and
-application programs that often go beyond what is available under
-Unix. One little-known gem is "dialog", a utility for creating
-professional-looking dialog boxes from within shell scripts. This
-article presents a tutorial introduction to the dialog utility, and
-shows examples of how and where it can be used</em></p>
-<p>As he explains, dialog is a real gem in making
-professional-looking dialog boxes with ease. It creates a variety
-of dialog boxes, menus, check lists etc.. It is usually installed
-by default. If not, you can download it from <a href=
-"http://invisible-island.net/dialog/" target="_top">Thomas
-Dickey</a>'s site.</p>
-<p>The above-mentioned article gives a very good overview of its
-uses and capabilites. The man page has more details. It can be used
-in variety of situations. One good example is building of linux
-kernel in text mode. Linux kernel uses a modified version of dialog
-tailored for its needs.</p>
-<p>dialog was initially designed to be used with shell scripts. If
-you want to use its functionality in a c program, then you can use
-libdialog. The documentation regarding this is sparse. Definitive
-reference is the dialog.h header file which comes with the library.
-You may need to hack here and there to get the required output. The
-source is easily customizable. I have used it on a number of
