# Gramps - a GTK+/GNOME based genealogy program
#
# Copyright (C) 2000-2003 Donald N. Allingham
#
# Modified September 2002 by Gary Shao
#
# Added line_break() method to TextDoc class to allow breaking a line
# in a paragraph (in those document generators that support it).
#
# Added start_listing() and end_listing() methods to TextDoc class to
# allow displaying text blocks without automatic filling and justification.
# Creating a new listing element seems called for because many document
# generator implementation have to use a different mechanism for text
# that is not going to be automatically filled and justified than that
# used for normal paragraphs. Examples are <pre> tags in HTML, using
# the Verbatim environment in LaTeX, and using the Preformatted class
# in reportlab for generating PDF.
#
# Added another option, FONT_MONOSPACE, for use as a font face. This
# calls for a fixed-width font (e.g. Courier). It is intended primarily
# for supporting the display of text where alignment by character position
# may be important, such as in code source or column-aligned data.
# Especially useful in styles for the new listing element discussed above.
#
# Added start_italic() and end_italic() methods to TextDoc class to
# complement the emphasis of text in a paragraph by bolding with the
# ability to italicize segments of text in a paragraph.
#
# Added the show_link() method to TextDoc to enable the creation of
# hyperlinks in HTML output. Only produces active links in HTML, while
# link will be represented as text in other generator output. (active
# links are technically possible in PDF documents, but the reportlab
# modules the PDF generator is based on does not support them at this
# time)
