          The value is the maximum number of chars the  user  may
80
          type  into  the  field,  regardles of field width.  For
81
          example, if the field width is set to 20 and the  fixed
82
          value  is  10,  the  user  will only be able to type 10
83
          characters into the field which is 20 characters long.

     Name:           <STRONG>validate</STRONG>
116
     Class:          <STRONG>Command</STRONG>
117
     Command-Line Switch:           <STRONG>-validate</STRONG>
118
 
119
          The validate option allows specification of  a  valida-
120
          tion  mechanism.  Standard character validation such as
121
          <STRONG>numeric</STRONG>, <STRONG>alphabetic</STRONG>, <STRONG>integer</STRONG>,  <STRONG>hexidecimal</STRONG>,  <STRONG>real</STRONG>,  and
122
          <STRONG>alphanumeric</STRONG>  can  be  handled  through the use of key-
123
          words.  Should more extensive validation be  necessary,
124
          the  value  may  contain  the name of a command script.
125
          The script should return a  boolean  value.   True  for
126
          valid,  false  for invalid.  If false is returned, then
127
          the procedure associated with the invalid  option  will
128
          be  invoked.   If  the validation script contains any <STRONG>%</STRONG>
129
          characters,  then  the  script  will  not  be  executed
130
          directly.   Instead,  a new script will be generated by
131
          replacing each <STRONG>%</STRONG>, and the character following it,  with
132
          information   from  the  entryfield.   The  replacement
133
          depends on the character following the <STRONG>%</STRONG>, as defined in
134
          the list below.
135
 
136
     <STRONG>%c</STRONG>   Replaced with the current input character.
137
 
138
     <STRONG>%P</STRONG>   Replaced with the contents of the  entryfield  modified
139
          to  include the latest keystoke.  This is equivalent to
140
          peeking at  the  future  contents,  enabling  rejection
141
          prior to the update.
142
 
143
     <STRONG>%S</STRONG>   Replaced with the current contents  of  the  entryfield
144
          prior to the latest keystroke being added.
145
 
146
     <STRONG>%W</STRONG>   Replaced with the entryfield widget pathname.

<H2>DESCRIPTION</H2><PRE>
156
     The <STRONG>entryfield</STRONG> command creates an enhanced text entry widget
157
     with  an  optional associated label.  Addtional options sup-
158
     port validation and establishing a upper limit on the number
159
     of characters which may be entered in the field.

<H2>METHODS</H2><PRE>
166
     The <STRONG>entryfield</STRONG> command creates a new Tcl command whose  name
167
     is  <EM>pathName</EM>.   This  command  may be used to invoke various
168
     operations on the widget.   It  has  the  following  general
169
     form:
170
 
171
          <EM>pathName</EM> <EM>option</EM> ?<EM>arg</EM> <EM>arg</EM> ...?
172
 
173
     <EM>Option</EM> and the <EM>arg</EM>s determine the exact behavior of the com-
174
     mand.   The  following  commands are possible for entryfield
175
     widgets:

<H2>WIDGET-SPECIFIC METHODS</H2><PRE>
189
     <EM>pathName</EM> <STRONG>cget</STRONG> <EM>option</EM>
190
          Returns the current value of the  configuration  option
191
          given  by  <EM>option</EM>.   <EM>Option</EM>  may have any of the values
192
          accepted by the <STRONG>entryfield</STRONG> command.
193
 
194
     <EM>pathName</EM> <STRONG>childsite</STRONG>
195
          Returns the path name of the child site.
196
 
197
     <EM>pathName</EM> <STRONG>clear</STRONG>
198
          Clear entry widget
199
 
200
     <EM>pathName</EM> <STRONG>configure</STRONG> ?<EM>option</EM>? ?<EM>value</EM> <EM>option</EM> <EM>value</EM> ...?
201
          Query  or  modify  the  configuration  options  of  the
202
          widget.   If  no  <EM>option</EM>  is  specified, returns a list
203
          describing all of the available  options  for  <EM>pathName</EM>
204
          (see  <STRONG>Tk_ConfigureInfo</STRONG> for information on the format of
205
          this list).  If <EM>option</EM> is specified with no <EM>value</EM>, then
206
          the  command  returns  a  list describing the one named
207
          option (this list will be identical to the  correspond-
208
          ing  sublist  of  the  value  returned  if no <EM>option</EM> is
209
          specified).  If one or more  <EM>option</EM> - <EM>value</EM>  pairs  are
210
          specified,  then  the command modifies the given widget
211
          option(s) to have the given value(s);  in this case the
212
          command  returns  an empty string.  <EM>Option</EM> may have any
213
          of the values accepted by the <STRONG>entryfield</STRONG> command.
