Name:	childSitePos
Class:	Position
Command-Line Switch:	-childsitepos



  

  
Specifies the position of the child site in the entry field: n,
      s, e, or w. The default is e.






Name:	command
Class:	Command
Command-Line Switch:	-command



  

  
Specifies a Tcl command to be executed upon detection of a Return key
      press event.






Name:	fixed
Class:	Fixed
Command-Line Switch:	-fixed



  

  
Restrict entry to the specified number of chars. A value of 0, which is
      the default, denotes no limit. The value is the maximum number of chars
      the user may type into the field, regardles of field width. For example,
      if the field width is set to 20 and the fixed value is 10, the user will
      only be able to type 10 characters into the field which is 20 characters
      long.






Name:	focusCommand
Class:	Command
Command-Line Switch:	-focuscommand



  

  
Specifies a Tcl command to be executed upon reception of focus.






Name:	invalid
Class:	Command
Command-Line Switch:	-invalid



  

  
Specifies a Tcl command to be executed upon determination of invalid
      input. The default is bell.






Name:	textBackground
Class:	Background
Command-Line Switch:	-textbackground



  

  
Background color for inside textual portion of the entry field. The value
      may be given in any of the forms acceptable to Tk_GetColor.






Name:	textFont
Class:	Font
Command-Line Switch:	-textfont



  

  
Name of font to use for display of text in entryfield. The value may be
      given in any of the forms acceptable to Tk_GetFont.






Name:	pasting
Class:	Behavior
Command-Line Switch:	-pasting



  

  
Option to enable/disable pasting into the entry component of the
      entryfield. Valid values are 0 (disabled) or 1 (enabled). Defaults to
    1.






Name:	validate
Class:	Command
Command-Line Switch:	-validate



  

  
The validate option allows specification of a validation mechanism.
      Standard character validation such as numeric, alphabetic,
      integer, hexidecimal, real, and alphanumeric
      can be handled through the use of keywords. Should more extensive
      validation be necessary, the value may contain the name of a command
      script. The script should return a boolean value. True for valid, false
      for invalid. If false is returned, then the procedure associated with the
      invalid option will be invoked. If the validation script contains any
      % characters, then the script will not be executed directly.
      Instead, a new script will be generated by replacing each %, and
      the character following it, with information from the entryfield. The
      replacement depends on the character following the %, as defined in
      the list below.





  
%c

  
Replaced with the current input character.

  
%P

  
Replaced with the contents of the entryfield modified to include the
      latest keystoke. This is equivalent to peeking at the future contents,
      enabling rejection prior to the update.

  
%S

  
Replaced with the current contents of the entryfield prior to the latest
      keystroke being added.

  
%W

  
Replaced with the entryfield widget pathname.
















The iwidgets::entryfield command creates an enhanced text
    entry widget with an optional associated label. Addtional options support
    validation and establishing a upper limit on the number of characters which
    may be entered in the field.
  














The iwidgets::entryfield command creates a new Tcl command
    whose name is pathName. This command may be used to invoke various
    operations on the widget. It has the following general form:




pathName option ?arg arg ...?




Option and the args determine the exact behavior of
    the command. The following commands are possible for entryfield widgets:








delete	get	icursor	index	
insert	scan	selection	xview	


See the "entry" manual entry for details on the
    associated methods.









  

  
Returns the current value of the configuration option given by
      option. Option may have any of the values accepted by the
      iwidgets::entryfield command.

  

  
Returns the path name of the child site.

  

  
Clear entry widget

  

  
Query or modify the configuration options of the widget. If no
      option is specified, returns a list describing all of the available
      options for pathName (see Tk_ConfigureInfo for information
      on the format of this list). If option is specified with no
      value, then the command returns a list describing the one named
      option (this list will be identical to the corresponding sublist of the
      value returned if no option is specified). If one or more
      option-value pairs are specified, then the command modifies the
      given widget option(s) to have the given value(s); in this case the
      command returns an empty string. Option may have any of the values
      accepted by the iwidgets::entryfield command.

      component item.
