.TH "XmDataField" "library call" .SH NAME \fBXmDataField\fP \(em The DataField widget class .SH SYNOPSIS .nf #include .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)\&. .PP .TS tab() box; c s s s s l| l| l| l| l. \fBXmDataField Resource Set\fP \fBName\fP\fBClass\fP\fBType\fP\fBDefault\fP\fBAccess\fP _____ XmNalignmentXmCAlignmentunsigned charXmALIGNMENT_BEGINNINGCSG _____ XmNautoFillXmCAutoFillBooleanTrueCSG _____ XmNpictureXmCPictureStringNULLCSG _____ XmNpictureErrorCallbackXmCCallbackXtCallbackListNULLC _____ XmNvalidateCallbackXmCCallbackXtCallbackListNULLC _____ .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\&. .PP .TS tab() box; c s s s s l| l| l| l| l. \fBXmTextFieldResource Set\fP \fBName\fP\fBClass\fP\fBType\fP\fBDefault\fP\fBAccess\fP _____ XmNactivateCallbackXmCCallbackXtCallbackListNULLC _____ XmNblinkRateXmCBlinkRateint500CSG _____ XmNcolumnsXmCColumnsshortdynamicCSG _____ XmNcursorPositionXmCCursorPositionXmTextPosition0CSG _____ XmNcursorPositionVisibleXmCCursorPositionVisibleBooleandynamicCSG _____ XmNdestinationCallbackXmCCallbackXtCallbackListNULLC _____ XmNeditableXmCEditableBooleanTrueCSG _____ XmNfocusCallbackXmCCallbackXtCallbackListNULLC _____ XmNfontListXmCFontListXmFontListdynamicCSG _____ XmNgainPrimaryCallbackXmCCallbackXtCallbackListNULLC _____ XmNlosePrimaryCallbackXmCCallbackXtCallbackListNULLC _____ XmNlosingFocusCallbackXmCCallbackXtCallbackListNULLC _____ XmNmarginHeightXmCMarginHeightDimension5CSG _____ XmNmarginWidthXmCMarginWidthDimension5CSG _____ XmNmaxLengthXmCMaxLengthintlargest integerCSG _____ XmNmodifyVerifyCallbackXmCCallbackXtCallbackListNULLC _____ XmNmodifyVerifyCallbackWcsXmCCallbackXtCallbackListNULLC _____ XmNmotionVerifyCallbackXmCCallbackXtCallbackListNULLC _____ XmNpendingDeleteXmCPendingDeleteBooleanTrueCSG _____ XmNrenderTableXmCRenderTableXmRenderTabledynamicCSG _____ XmNresizeWidthXmCResizeWidthBooleanFalseCSG _____ XmNselectionArrayXmCSelectionArrayXtPointerdefault arrayCSG _____ XmNselectionArrayCountXmCSelectionArrayCountint3CSG _____ XmNselectThresholdXmCSelectThresholdint5CSG _____ XmNvalueXmCValueString""CSG _____ XmNvalueChangedCallbackXmCCallbackXtCallbackListNULLC _____ XmNvalueWcsXmCValueWcswchar_t *(wchar_t *)""CSG _____ XmNverifyBellXmCVerifyBellBooleandynamicCSG _____ .TE .PP .TS tab() box; c s s s s l| l| l| l| l. \fBXmPrimitive Resource Set\fP \fBName\fP\fBClass\fP\fBType\fP\fBDefault\fP\fBAccess\fP _____ XmNbottomShadowColorXmCBottomShadowColorPixeldynamicCSG _____ XmNbottomShadowPixmapXmCBottomShadowPixmapPixmapXmUNSPECIFIED_PIXMAPCSG _____ XmNconvertCallbackXmCCallbackXtCallbackListNULLC _____ XmNforegroundXmCForegroundPixeldynamicCSG _____ XmNhelpCallbackXmCCallbackXtCallbackListNULLC _____ XmNhighlightColorXmCHighlightColorPixeldynamicCSG _____ XmNhighlightOnEnterXmCHighlightOnEnterBooleanFalseCSG _____ XmNhighlightPixmapXmCHighlightPixmapPixmapdynamicCSG _____ XmNhighlightThicknessXmCHighlightThicknessDimension2CSG _____ XmNlayoutDirectionXmCLayoutDirectionXmDirectiondynamicCG _____ XmNnavigationTypeXmCNavigationTypeXmNavigationTypeXmTAB_GROUPCSG _____ XmNpopupHandlerCallbackXmCCallbackXtCallbackListNULLC _____ XmNshadowThicknessXmCShadowThicknessDimension2CSG _____ XmNtopShadowColorXmCTopShadowColorPixeldynamicCSG _____ XmNtopShadowPixmapXmCTopShadowPixmapPixmapdynamicCSG _____ XmNtraversalOnXmCTraversalOnBooleanTrueCSG _____ XmNunitTypeXmCUnitTypeunsigned chardynamicCSG _____ XmNuserDataXmCUserDataXtPointerNULLCSG _____ .TE .PP .TS tab() box; c s s s s l| l| l| l| l. \fBCore Resource Set\fP \fBName\fP\fBClass\fP\fBType\fP\fBDefault\fP\fBAccess\fP _____ XmNacceleratorsXmCAcceleratorsXtAcceleratorsdynamicCSG _____ XmNancestorSensitiveXmCSensitiveBooleandynamicG _____ XmNbackgroundXmCBackgroundPixeldynamicCSG _____ XmNbackgroundPixmapXmCPixmapPixmapXmUNSPECIFIED_PIXMAPCSG _____ XmNborderColorXmCBorderColorPixelXtDefaultForegroundCSG _____ XmNborderPixmapXmCPixmapPixmapXmUNSPECIFIED_PIXMAPCSG _____ XmNborderWidthXmCBorderWidthDimension0CSG _____ XmNcolormapXmCColormapColormapdynamicCG _____ XmNdepthXmCDepthintdynamicCG _____ XmNdestroyCallbackXmCCallbackXtCallbackListNULLC _____ XmNheightXmCHeightDimensiondynamicCSG _____ XmNinitialResourcesPersistentXmCInitialResourcesPersistentBooleanTrueC _____ XmNmappedWhenManagedXmCMappedWhenManagedBooleanTrueCSG _____ XmNscreenXmCScreenScreen *dynamicCG _____ XmNsensitiveXmCSensitiveBooleanTrueCSG _____ XmNtranslationsXmCTranslationsXtTranslationsdynamicCSG _____ XmNwidthXmCWidthDimensiondynamicCSG _____ XmNxXmCPositionPosition0CSG _____ XmNyXmCPositionPosition0CSG _____ .TE .SS "Translations" .PP XmDataField inherits translations from XmTextField\&. .PP .SH Callback Routines A pointer to the following structure is passed to the list of routines for the XmNvalidateCallback: .nf typedef struct _XmDataFieldCallbackStruct { Widget w; /* The XmDataField */ String text; /* Proposed string */ Boolean accept; /* Accept return value, for validation */ } XmDataFieldCallbackStruct; .fi .SH "RELATED" .PP \fBCore\fP(3), \fBXmCreateDataField\fP(3), \fBXmPrimitive\fP(3), \fBXmTextFieldSetString\fP(3), \fBXmTextFieldSetStringWcs\fP(3), \fBXmVaCreateDataField\fP(3), and \fBXmVaCreateManagedDataField\fP(3)\&. .SH VERSION This manual page documents the XmDataField widget shipped in Motif version 2.2 .SH AUTHOR .br (c) 2002 by Integrated Computer Solutions, Inc. .LP Edited by Kevin Cook. .PP
