WIDGET-SPECIFIC OPTIONS
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.

DESCRIPTION
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.
METHODS
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:
ASSOCIATED METHODS
delete get icursor index
insert scan selection xview
See the "entry" manual entry for details on the associated methods.
WIDGET-SPECIFIC METHODS
pathName cget option
Returns the current value of the configuration option given by option. Option may have any of the
values accepted by the iwidgets::entryfield command.
pathName childsite
Returns the path name of the child site.
pathName clear
Clear entry widget
pathName configure ?option? ?value option value ...?
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.
COMPONENTS
Name: efchildsite
Class: frame
The efchildsite component is the user child site for the entry field. See the "frame" widget
manual entry for details on the efchildsite component item.
Name: entry
Class: entry
The entry component provides the entry field for user text input and display. See the "entry"
widget manual entry for details on the entry component item.
