NAME
XmDataField -- The DataField widget class
SYNOPSIS
#include <Xm/DataF.h>
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 XmNalign-
ment resource.
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 pro-
ceeding to another field.
Classes
DataField inherits behavior, resources, and traits from Core, XmPrimi-
tive, and XmTextField.
The class pointer is xmDataFieldWidgetClass.
The class name is XmDataField.
New Resources
The following table defines a set of widget resources used by the pro-
grammer to specify data. The programmer can also set the resource val-
ues for the inherited classes to set attributes for this widget. To
reference a resource by name or by class in a .Xdefaults file, remove
the XmN or XmC prefix and use the remaining letters. To specify one of
the defined values for a resource in a .Xdefaults file, remove the Xm
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 XtSetValues (S), retrieved by using XtGetValues (G), or is
not applicable (N/A).

XmNalignment
When set to XmALIGNMENT_END, the widget aligns all its text
with the right hand side of the input area.
XmNautoFill
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.
XmNpicture
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.
Character interpretations
The following lists and defines the characters you can use in
a picture, and how the DataField widget interprets them.
# Any numeric digit
? Case insensitive letter
& Uppercase letter (forces lowercase to uppercase)
@ Case insensitive character
! Uppercase character
; Interpret the following character literally
* Repeat the following character some number of times
[] Characters within brackets are optional
{} Characters within braces are grouped
, Alternative values
Other characters are interpreted literally.
Set XmNpicture to NULL to disable regular expression
processing. The DataField widget is cleared whenever
the XmNpicture resource is changed.
XmNpictureErrorCallback
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.
XmNvalidateCallback
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.
Inherited Resources
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.
