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 Motif 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.
Keyboard navigation
Typical business applications demand better keyboard traversal than provided by Motif. 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 cor-
rect value before proceeding to another field.
Classes and Inherited Resources
DataField inherits behavior and resources from Core, XmPrimitive, and XmTextField. For a complete description of each resource, refer to
the OSF/Motif Programmers Reference.
Resources
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 format-
ted value.
The following lists and defines the characters you can use in a picture, and how the
DataField widget interprets them.
# Anynumericdigit

@ Caseinsensitivecharacter
! Uppercasecharacter
; Interpretthefollowingcharacterliterally
* Repeatthefollowingcharactersomenumberoftimes
[] Characterswithinbracketsareoptional
{} Characterswithinbracesaregrouped

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.
Callback Routines
typedef struct _XmDataFieldCallbackStruct {
Widget w; /* The XmDataField */
String text; /* Proposed string */
Boolean accept; /* Accept return value, for validation */
} XmDataFieldCallbackStruct;
