.SH NAME
\fBXmDataField\fP \(em The DataField widget class
.SH SYNOPSIS 
.nf
#include <Xm/DataF\&.h>
.fi
.SH DESCRIPTION
The DataField widget is a Data Presentation widget that handles display and entry of data as text.
The DataField widget is a subclass of the XmTextField widget intended for data entry 
applications. In addition to all of the normal XmTextField functionality, it supports regular 
expression-based parsing and acceptance/rejection of its input through the XmNpicture resource, 
and right justification through the XmNalignment resource. 
.PP
The DataField widget provides added capability by supporting several types of validation: a 
DataField widget containing an invalid value will not give-up focus; the user must enter a
correct value before proceeding to another field.
.SS "Classes"
.PP
DataField inherits behavior, resources, and traits from \fBCore\fP,
\fBXmPrimitive\fP, and \fBXmTextField\fP\&.
.PP
The class pointer is \fBxmDataFieldWidgetClass\fP\&.
.PP
The class name is \fBXmDataField\fP\&.
.SS "New Resources"
.PP
The following table defines a set of widget resources used by the
programmer to specify data\&. The programmer can also set the resource
values for the inherited classes to set attributes for this widget\&.
To reference a resource by name or by class in a \fB\&.Xdefaults\fP file,
remove the \fBXmN\fP or \fBXmC\fP prefix and use the remaining letters\&.
To specify one of the defined values for a resource in a \fB\&.Xdefaults\fP
file, remove the \fBXm\fP prefix and use the remaining letters (in
either lowercase or uppercase, but include any underscores between
words)\&. The codes in the access column indicate if the given resource
can be set at creation time (C), set by using \fBXtSetValues\fP
(S), retrieved by using \fBXtGetValues\fP (G), or is not
applicable (N/A)\&.

.TE
.IP "\fBXmNalignment\fP" 10
When set to XmALIGNMENT_END, the widget aligns all its text with the right hand side of the 
input area.
.IP "\fBXmNautoFill\fP" 10
When set to True, the widget "auto-fills" its contents when it can determine that the next 
character in the string must be a particular literal\&. For instance, the picture "###-####" 
automatically inserts a '-' character after receiving three numeric digits as input\&.
.IP "\fBXmNpicture\fP" 10
Specifies a picture for data entry in the widget. A picture acts as a template that formats
the value you enter in a field. An example would be the US Phone Number picture: (###)###-####.
The picture is used to convert characters entered into the field to a formatted value\&.
.RS
.IP "\fBCharacter interpretations\fP" 10
.PP
The following lists and defines the characters you can use in a picture, and how the
DataField widget interprets them.
.IP \fI#\fP
Any numeric digit
.IP \fI?\fP
Case insensitive letter
.IP \fI&\fP
Uppercase letter (forces lowercase to uppercase)
.IP \fI@\fP
Case insensitive character
.IP \fI!\fP
Uppercase character
.IP \fI;\fP
Interpret the following character literally
.IP \fI*\fP
Repeat the following character some number of times
.IP \fI[]\fP
Characters within brackets are optional
.IP \fI{}\fP
Characters within braces are grouped
.IP \fI,\fP
Alternative values
.IP ""
Other characters are interpreted literally.
.IP ""
Set XmNpicture to NULL to disable regular expression processing. The DataField widget is 
cleared whenever the XmNpicture resource is changed.
.RE
.IP "\fBXmNpictureErrorCallback\fP" 10
Specifies a list of callbacks to be called when the XmDataField widget determines that data is 
being entered that does not match the format specified by the XmNpicture resource.
.IP "\fBXmNvalidateCallback\fP" 10
Specifies a list of callbacks to be called when data has been entered in the XmDataField widget 
and the user has moved out of the XmDataField widget (usually by pressing the Tab key). The 
callbacks can reject the movement of focus. 
.PP
.SS "Inherited Resources"
.PP
DataField inherits behavior and resources from the
superclasses described in the following tables\&.
For a complete description of each resource, refer to the
reference page for that superclass\&.
