Barcode

The Barcode widget generates a barcode image representing a given text string.

XML Fields

  • XPath identifies the value to encode. Barcode reads this value and does not modify it.
  • Format selects the barcode symbology. Choose a format that is valid for the expected value and the target scanner.
  • Width sets the width of one bar in pixels, and Height sets the image height in pixels.
  • ShowValue displays the encoded text beneath the image when set to true.
  • Hints provides help text and Rules contains conditional form behavior.

Read-Only Nature

The Barcode widget is read-only. The string value to be encoded into the barcode is set during process definition and cannot be changed by the user.

Customization

  • Width: Specifies the width of a single bar in pixels. Defaults to 4 pixels.
  • Height: Specifies the height of the barcode image in pixels. Defaults to 50 pixels.
