mlreportgen.dom.Preformatted class

Package: mlreportgen.dom
Superclasses: mlreportgen.dom.Paragraph

Preformatted block of text

Description

Use objects of the mlreportgen.dom.Preformatted class to preserve the white-space formatting of text. White space-formatting uses spaces, line feeds, and monospace fonts to render text on multiple lines and to control indentation. For example, use an mlreportgen.dom.Preformatted object to add program code to a report.

If you do not set the FontFamilyName or Whitespace properties, the DOM API uses the default values for the report type (HTML, Microsoft® Word, or PDF) so that white-space formatting is preserved. You can override the default values by setting the FontFamilyName or Whitespace properties.

The mlreportgen.dom.Preformatted class is a handle class.
