Display Value value Text Text to display in the field. Save Input To saveInto List of Save One or more variables that are updated with the text when the user changes it. Use a!save() to save a modified or alternative value to a variable. Refresh After refreshAfter Text Determines when the interface is refreshed with the saved value from the barcode field. Valid values are "KEYPRESS" to refresh after every character typed into the field and "UNFOCUS" (the default value) to refresh when the user deselects the field after changing its value. Required required Boolean Determines if a value is required to submit the form. Default: false. Required Message requiredMessage Text Custom message to display when the field's value is required and not provided. Read-only readOnly Boolean Determines if the field should display as not editable. Default: false. Disabled disabled Boolean Determines if the field should display as potentially editable but grayed out. Default: false. Validations validations List of Text String Validation errors to display below the field when the value is not null. Validation Group validationGroup Text When present, the requiredness of the field is only evaluated when a button in the same validation group is pressed. The value for this parameter cannot contain spaces. For example, “validation group” is not a valid value. You need to add an underscore between words: “validation_group”. See the following recipes for more information: Configure Buttons with Conditional Requiredness Validation Groups for Buttons with Multiple Validation Rules' Alignment align Text Determines alignment of the text value. Valid values: "LEFT" (default), "CENTER", "RIGHT". Placeholder placeholder Text Text to display in the field when it is empty. Does not show if the field is read only. Help Tooltip helpTooltip Text Displays a help icon with the specified text as a tooltip. The tooltip displays a maximum of 500 characters. The help icon does not show when the label position is "COLLAPSED". Masked masked Boolean Determines if the value is obscured from view. Default: false. Accessibility Text accessibilityText Text Additional text to be announced by screen readers. Used only for accessibility; produces no visible change. Visibility showWhen Boolean Determines whether the component is displayed on the interface. When set to false, the component is hidden and is not evaluated. Default: true. Usage considerations Scanning on different devices The native device's camera is used on mobile devices to scan barcodes. The masked parameter is ignored on offline interfaces on Android devices. All barcode components are shown un-masked in this case. The barcode component does not support barcode scanning on Appian's web user interfaces. Instead, users can manually enter barcode values. Using the acceptedTypes parameter Use the acceptedTypes parameter to specify one or more type(s) of barcode.
