  <h2 id="overview">Overview</h2>

  <h3 id="ov_what">What Is Mentry?</h3>

  <p>Mentry is a library package for Tcl/Tk versions 8.0 or higher, written in
................................................................................
  <p>you can make sure that the three entries will only accept numeric input,
  thus providing a comfortable and safe user interface for editing 10-digit
  phone numbers.</p>

  <h3 id="ov_get">How to Get It?</h3>

  <p>Mentry is available for free download from the same URL as Wcb.&nbsp; The
  distribution file is <code>mentry3.9.tar.gz</code> for UNIX and
  <code>mentry3_9.zip</code> for Windows.&nbsp; These files contain the same
  information, except for the additional carriage return character preceding
  the linefeed at the end of each line in the text files for Windows.</p>

  <p>Mentry is also included in tklib, which has the address</p>

  <blockquote>
    <address>
................................................................................
  the <code>auto_path</code> variable.&nbsp; For example, you can install it as
  a directory at the same level as the Tcl and Tk script libraries.&nbsp; The
  locations of these library directories are given by the
  <code>tcl_library</code> and <code>tk_library</code> variables,
  respectively.</p>

  <p>To install Mentry <i>on UNIX</i>, <code>cd</code> to the desired directory
  and unpack the distribution file <code>mentry3.9.tar.gz</code>:</p>

  <blockquote>
    <pre>
gunzip -c mentry3.9.tar.gz | tar -xf -
</pre>
  </blockquote>

  <p>On most UNIX systems this can be replaced with</p>

  <blockquote>
    <pre>
tar -zxf mentry3.9.tar.gz
</pre>
  </blockquote>

  <p>Both commands will create a directory named <code>mentry3.9</code>, with
  the subdirectories <code>demos</code>, <code>doc</code>, and
  <code>scripts</code>.</p>

  <p><i>On Windows</i>, use WinZip or some other program capable of unpacking
  the distribution file <code>mentry3_9.zip</code> into the directory
  <code>mentry3.9</code>, with the subdirectories <code>demos</code>,
  <code>doc</code>, and <code>scripts</code>.</p>

  <p>The file <code>mentryThemes.tcl</code> in the <code>scripts</code>
  directory is only needed for applications using the package Mentry_tile (see
  next section).</p>

  <p>Notice that in tklib the Mentry <code>demos</code> directory is replaced
................................................................................
  0.4 or higher, and <code>tileqt</code> itself won't work with tile versions
  earlier than 0.7.</p>

  <h3 id="ex_phoneNumber">A mentry Widget for Phone Numbers</h3>

  <p>Let's resume the <a href="#ov_example">example</a> mentioned in the
................................................................................
  Overview in a bit more systematical manner.&nbsp; First, we will write a
  procedure for creating a mentry widget that allows to display and edit
  10-digit phone numbers and accepts any configuration options supported by the
  <code><a href="mentryWidget.html">mentry::mentry</a></code> command:</p>

  <blockquote>
    <pre>
#------------------------------------------------------------------------------
# phoneNumberMentry
#
# Creates a new mentry widget win that allows to display and edit 10-digit
# phone numbers.  Sets the type attribute of the widget to PhoneNumber and
# returns the name of the newly created widget.
#------------------------------------------------------------------------------
proc phoneNumberMentry {win args} {
    #

    # Create a mentry widget consisting of two entries of width 3 and one of
    # width 4, separated by "-" characters, and set its type to PhoneNumber
    #
    eval [list mentry::mentry $win] $args
    $win configure -body {3 - 3 - 4}
    $win attrib type PhoneNumber

    #
    # Allow only decimal digits in all entry children; use
    # wcb::cbappend (or wcb::cbprepend) instead of wcb::callback
    # in order to keep the wcb::checkEntryLen callback,
    # registered by mentry::mentry for all entry children
    #
    for {set n 0} {$n &lt; 3} {incr n} {
        wcb::cbappend [$win entrypath $n] before insert wcb::checkStrForNum
        $win adjustentry $n "0123456789"
    }

    return $win
}
................................................................................
  characters specified by that string.</p>

  <p>Our second procedure outputs a phone number to a mentry widget having a
  <code>type</code> attribute value of <code>"PhoneNumber"</code>:</p>

  <blockquote>
    <pre>
#------------------------------------------------------------------------------
# putPhoneNumber
#
# Outputs the phone number num to the mentry widget win of type PhoneNumber.
# The phone number must be a string of length 10, consisting of decimal digits.
#------------------------------------------------------------------------------
proc putPhoneNumber {num win} {
    #

    # Check the syntax of num
    #
    if {[string length $num] != 10 || ![regexp {^[0-9]*$} $num]} {
        return -code error "expected 10 decimal digits but got \"$num\""
    } 

    #

    # Check the widget and display the properly formatted phone number
    #
    checkIfPhoneNumberMentry $win
    $win put 0 [string range $num 0 2] [string range $num 3 5] \
               [string range $num 6 9]
}
</pre>
  </blockquote>

................................................................................

  <p>Next, we need a procedure that returns the phone number contained in a
  mentry widget having a <code>type</code> attribute value of
  <code>"PhoneNumber"</code>:</p>

  <blockquote>
    <pre>
#------------------------------------------------------------------------------
# getPhoneNumber
#
# Returns the phone number contained in the mentry widget win of type
# PhoneNumber.
#------------------------------------------------------------------------------
proc getPhoneNumber win {
    #

    # Check the widget
    #
    checkIfPhoneNumberMentry $win

    #

    # Generate an error if any entry child is empty or incomplete
    #
    for {set n 0} {$n &lt; 3} {incr n} {
        if {[$win isempty $n]} {
            focus [$win entrypath $n]
            return -code error EMPTY
        }
        if {![$win isfull $n]} {
            focus [$win entrypath $n]
            return -code error INCOMPL
        }
    }

    #

    # Return the phone number built from the
    # values contained in the entry children
    #
    $win getarray strs
    return $strs(0)$strs(1)$strs(2)
}
</pre>
  </blockquote>

  <p>The procedure runs over the indices of the entry children of the given
................................................................................

  <p>The last two procedures presented above contain an invocation of the
  command <code>checkIfPhoneNumberMentry</code>, which is implemented as
  folows:</p>

  <blockquote>
    <pre>
#------------------------------------------------------------------------------
# checkIfPhoneNumberMentry
#
# Generates an error if win is not a mentry widget of type PhoneNumber.
#------------------------------------------------------------------------------
proc checkIfPhoneNumberMentry win {
    if {![winfo exists $win]} {
        return -code error "bad window path name \"$win\""
    }

    if {[string compare [winfo class $win] "Mentry"] != 0 ||
        [string compare [$win attrib type] "PhoneNumber"] != 0} {

  implements the procedures <code>ethernetAddrMentry</code>,
  <code>putEthernetAddr</code>, and <code>getEthernetAddr</code>; the last two

  string of the form <code>"XX:XX:XX:XX:XX:XX"</code>, where each
  <code>"XX"</code> must be a hexadecimal string in the range <code>0</code> -
  <code>255</code>:</p>

  <blockquote>

    <code>datetime1.tcl</code> and <code>datetime2.tcl</code>:

      <blockquote>

  of the <code>-base</code> option when passing the name of the time mentry to
  the same procedure.</p>

  <p>The demo script <code>datetime2.tcl</code> is simpler:</p>

  <p>The Mentry distribution contains also tile-based counterparts of the demo
  scripts discussed above.&nbsp; As described in the <a href="#ov_tile">More on
  Mentry_tile</a> section of this tutorial, it is quite easy to port an
  application using the Mentry package to one based on Mentry_tile.&nbsp; For
  example, let's see how to transform the demo script
  <code>phonenumber.tcl</code> into a tile-based one, called
  <code>phonenumber_tile.tcl</code>.&nbsp; The changes are shown below in
  <span>red</span> color:</p>

  <h2 id="overview">Overview</h2>

  <h3 id="ov_what">What Is Mentry?</h3>

  <p>Mentry is a library package for Tcl/Tk versions 8.0 or higher, written in
................................................................................
  <p>you can make sure that the three entries will only accept numeric input,
  thus providing a comfortable and safe user interface for editing 10-digit
  phone numbers.</p>

  <h3 id="ov_get">How to Get It?</h3>

  <p>Mentry is available for free download from the same URL as Wcb.&nbsp; The
  distribution file is <code>mentry3.10.tar.gz</code> for UNIX and
  <code>mentry3_10.zip</code> for Windows.&nbsp; These files contain the same
  information, except for the additional carriage return character preceding
  the linefeed at the end of each line in the text files for Windows.</p>

  <p>Mentry is also included in tklib, which has the address</p>

  <blockquote>
    <address>
................................................................................
  the <code>auto_path</code> variable.&nbsp; For example, you can install it as
  a directory at the same level as the Tcl and Tk script libraries.&nbsp; The
  locations of these library directories are given by the
  <code>tcl_library</code> and <code>tk_library</code> variables,
  respectively.</p>

  <p>To install Mentry <i>on UNIX</i>, <code>cd</code> to the desired directory
  and unpack the distribution file <code>mentry3.10.tar.gz</code>:</p>

  <blockquote>
    <pre>
gunzip -c mentry3.10.tar.gz | tar -xf -
</pre>
  </blockquote>

  <p>On most UNIX systems this can be replaced with</p>

  <blockquote>
    <pre>
tar -zxf mentry3.10.tar.gz
</pre>
  </blockquote>

  <p>Both commands will create a directory named <code>mentry3.10</code>, with
  the subdirectories <code>demos</code>, <code>doc</code>, and
  <code>scripts</code>.</p>

  <p><i>On Windows</i>, use WinZip or some other program capable of unpacking
  the distribution file <code>mentry3_10.zip</code> into the directory
  <code>mentry3.10</code>, with the subdirectories <code>demos</code>,
  <code>doc</code>, and <code>scripts</code>.</p>

  <p>The file <code>mentryThemes.tcl</code> in the <code>scripts</code>
  directory is only needed for applications using the package Mentry_tile (see
  next section).</p>

  <p>Notice that in tklib the Mentry <code>demos</code> directory is replaced
................................................................................
  0.4 or higher, and <code>tileqt</code> itself won't work with tile versions
  earlier than 0.7.</p>

  <h3 id="ex_phoneNumber">A mentry Widget for Phone Numbers</h3>

  <p>Let's resume the <a href="#ov_example">example</a> mentioned in the
................................................................................
  Overview in a bit more systematical manner.&nbsp; First, we will write a
  procedure for creating a mentry widget that allows to display and edit
  10-digit phone numbers and accepts any configuration options supported by the
  <code><a href="mentryWidget.html">mentry::mentry</a></code> command:</p>

  <blockquote>
    <pre>
<span class="cmt">#------------------------------------------------------------------------------
# phoneNumberMentry
#
# Creates a new mentry widget win that allows to display and edit 10-digit
# phone numbers.  Sets the type attribute of the widget to PhoneNumber and
# returns the name of the newly created widget.
#------------------------------------------------------------------------------</span>
proc phoneNumberMentry {win args} {

    <span class="cmt">#
    # Create a mentry widget consisting of two entries of width 3 and one of
    # width 4, separated by "-" characters, and set its type to PhoneNumber
    #</span>
    eval [list mentry::mentry $win] $args
    $win configure -body {3 - 3 - 4}
    $win attrib type PhoneNumber

    <span class="cmt">#
    # Allow only decimal digits in all entry children; use
    # wcb::cbappend (or wcb::cbprepend) instead of wcb::callback
    # in order to keep the wcb::checkEntryLen callback,
    # registered by mentry::mentry for all entry children
    #</span>
    for {set n 0} {$n &lt; 3} {incr n} {
        wcb::cbappend [$win entrypath $n] before insert wcb::checkStrForNum
        $win adjustentry $n "0123456789"
    }

    return $win
}
................................................................................
  characters specified by that string.</p>

  <p>Our second procedure outputs a phone number to a mentry widget having a
  <code>type</code> attribute value of <code>"PhoneNumber"</code>:</p>

  <blockquote>
    <pre>
<span class="cmt">#------------------------------------------------------------------------------
# putPhoneNumber
#
# Outputs the phone number num to the mentry widget win of type PhoneNumber.
# The phone number must be a string of length 10, consisting of decimal digits.
#------------------------------------------------------------------------------</span>
proc putPhoneNumber {num win} {

    <span class="cmt">#
    # Check the syntax of num
    #</span>
    if {[string length $num] != 10 || ![regexp {^[0-9]*$} $num]} {
        return -code error "expected 10 decimal digits but got \"$num\""
    } 


    <span class="cmt">#
    # Check the widget and display the properly formatted phone number
    #</span>
    checkIfPhoneNumberMentry $win
    $win put 0 [string range $num 0 2] [string range $num 3 5] \
               [string range $num 6 9]
}
</pre>
  </blockquote>

................................................................................

  <p>Next, we need a procedure that returns the phone number contained in a
  mentry widget having a <code>type</code> attribute value of
  <code>"PhoneNumber"</code>:</p>

  <blockquote>
    <pre>
<span class="cmt">#------------------------------------------------------------------------------
# getPhoneNumber
#
# Returns the phone number contained in the mentry widget win of type
# PhoneNumber.
#------------------------------------------------------------------------------</span>
proc getPhoneNumber win {

    <span class="cmt">#
    # Check the widget
    #</span>
    checkIfPhoneNumberMentry $win


    <span class="cmt">#
    # Generate an error if any entry child is empty or incomplete
    #</span>
    for {set n 0} {$n &lt; 3} {incr n} {
        if {[$win isempty $n]} {
            focus [$win entrypath $n]
            return -code error EMPTY
        }
        if {![$win isfull $n]} {
            focus [$win entrypath $n]
            return -code error INCOMPL
        }
    }


    <span class="cmt">#
    # Return the phone number built from the
    # values contained in the entry children
    #</span>
    $win getarray strs
    return $strs(0)$strs(1)$strs(2)
}
</pre>
  </blockquote>

  <p>The procedure runs over the indices of the entry children of the given
................................................................................

  <p>The last two procedures presented above contain an invocation of the
  command <code>checkIfPhoneNumberMentry</code>, which is implemented as
  folows:</p>

  <blockquote>
    <pre>
<span class="cmt">#------------------------------------------------------------------------------
# checkIfPhoneNumberMentry
#
# Generates an error if win is not a mentry widget of type PhoneNumber.

    if {![winfo exists $win]} {
        return -code error "bad window path name \"$win\""
    }

    if {[string compare [winfo class $win] "Mentry"] != 0 ||
        [string compare [$win attrib type] "PhoneNumber"] != 0} {

  <p>The Mentry distribution contains also tile-based counterparts of the demo
  scripts discussed above.&nbsp; As described in the <a href="#ov_tile">More on
  Mentry_tile</a> section of this tutorial, it is quite easy to port an
  application using the Mentry package to one based on Mentry_tile.&nbsp; For
  example, let's see how to transform the demo script
  <code>phonenumber.tcl</code> into a tile-based one, called
  <code>phonenumber_tile.tcl</code>.&nbsp; The changes are shown below in

    <dt id="description"><b>DESCRIPTION</b></dt>

    <dd>The <code><b>mentry::mentry</b></code> command creates a new window
    named <code><i>pathName</i></code> and of the class
    <code><b>Mentry</b></code>, and makes it into a <b>mentry</b> widget.&nbsp;
    Additional options, described above, may be specified on the command line
    or in the option database to configure aspects of the mentry such as its
    colors, font, and children.&nbsp; The <code><b>mentry::mentry</b></code>
    command returns its <code><i>pathName</i></code> argument.&nbsp; At the
    time this command is invoked, there must not exist a window named
    <code><i>pathName</i></code>, but <code><i>pathName</i></code>'s parent
    must exist.</dd>

    <dd class="tm">The word <i>mentry</i> is an abbreviation of
    <i>multi-entry</i>.&nbsp; A mentry is a mega-widget consisting of any
    number of entries separated by labels, all embedded in a frame.&nbsp; Due
    to appropriately chosen configuration options for the entries and labels, a
    mentry widget looks like one single entry containing preinserted text
    pieces that cannot be moved, changed, or deleted by the user.</dd>

    <dd class="tm">As described above, the initial width of each entry child
    (specified by the <code><b><a href="#body">-body</a></b></code>
    configuration option) also determines the maximal number of characters that
    can be inserted into it.&nbsp; This is achieved with the aid of the
    <code><b><a href="wcbRef.html#callback">wcb::callback</a></b></code>
    command, by registering the <code><b><a href=
    "wcbRef.html#entrycb">wcb::checkEntryLen</a></b></code>
    before-<code><b>insert</b></code> callback with the entry child.&nbsp; In
    order to keep this callback, additional before-<code><b>insert</b></code>
    callbacks (if needed) should only be registered with the <code><b><a href=
    "wcbRef.html#cbappend">wcb::cbappend</a></b></code> and <code><b><a href=
    "wcbRef.html#cbprepend">wcb::cbprepend</a></b></code> commands.&nbsp; When
    reaching this limit in an entry having the input focus, the latter is set
    automatically to the next enabled entry child, the contents of that widget
    is selected, and the insertion cursor is set to its end.&nbsp; This is made
    sure by defining an appropriate after-<code><b>insert</b></code> callback,
    which must be kept to be the last such callback for the entry.&nbsp; For
    this reason, additional after-<code><b>insert</b></code> callbacks (if
    needed) should only be registered with the
    <code><b>wcb::cbprepend</b></code> command.&nbsp; The same command should
    be used exclusively to define after-<code><b>motion</b></code> callbacks
    (if needed), because <code><b>mentry::mentry</b></code> registers one that
    must be the last after-<code><b>motion</b></code> callback for each entry
    child.</dd>

    <dd class="tm">Each mentry widget may have any number of <b>attributes</b>,
    which can be used in commands that create or manipulate mentry widgets for
    particular purposes.&nbsp; For example, each date mentry created by the
    <code><b><a href=
    "mentryDateTime.html#dateMentry">mentry::dateMentry</a></b></code> command
    has a <code><b>type</b></code> attribute having the value
    <code>"Date"</code> and a <code><b>format</b></code> attribute specifying
    the meanings of its components.&nbsp; The values of these attributes are
    queried and used in the bodies of the procedures <code><b><a href=
    "mentryDateTime.html#putClockVal">mentry::putClockVal</a></b></code> and
    <code><b><a href=
    "mentryDateTime.html#getClockVal">mentry::getClockVal</a></b></code>.</dd>

    <dt class="tm" id="indices"><b>INDICES</b></dt>

    <dd>Some of the widget commands for mentries take an index as
    argument.&nbsp; An index specifies a particular entry or label child of the
    mentry, in any of the following ways:</dd>

    <dd class="tm">
      <table border="0" cellpadding="6" cellspacing="0">
        <tr valign="top">
          <td><code><i>number&nbsp;&nbsp;</i></code></td>

          <td>Specifies the child as a numerical index, where <code>0</code>
          corresponds to the first entry or label child.</td>
        </tr>

        <tr valign="top">
          <td><code><b>end</b></code></td>

          <td>Indicates the last entry or label child of the mentry.</td>
        </tr>
      </table>
    </dd>

    <dd class="tm">The word <code><b>end</b></code> can be abbreviated as
    <code><b>en</b></code> or <code><b>e</b></code>.&nbsp; Out-of-range indices
