#
# Font specifications.
#
# This file, [source]d at initialization time, sets up the following
# symbolic fonts based on the current platform:
#
# TkDefaultFont	-- default for GUI items not otherwise specified
# TkTextFont	-- font for user text (entry, listbox, others)
# TkFixedFont	-- standard fixed width font
# TkHeadingFont	-- headings (column headings, etc)
# TkCaptionFont -- dialog captions (primary text in alert dialogs, etc.)
# TkTooltipFont	-- font to use for tooltip windows
# TkIconFont	-- font to use for icon captions
# TkMenuFont	-- used to use for menu items
#
# In Tk 8.5, some of these fonts may be provided by the TIP#145 implementation
# (On Windows and Mac OS X as of Oct 2007).
#
# +++ Platform notes:
#
# Windows:
#	The default system font changed from "MS Sans Serif" to "Tahoma"
# 	in Windows XP/Windows 2000.
#
#	MS documentation says to use "Tahoma 8" in Windows 2000/XP,
#	although many MS programs still use "MS Sans Serif 8"
#
#	Should use SystemParametersInfo() instead.
#
# Mac OSX / Aqua:
#	Quoth the Apple HIG:
#	The _system font_ (Lucida Grande Regular 13 pt) is used for text
#	in menus, dialogs, and full-size controls.
#	[...] Use the _view font_ (Lucida Grande Regular 12pt) as the default
#	font of text in lists and tables.
#	[...] Use the _emphasized system font_ (Lucida Grande Bold 13 pt)
#	sparingly. It is used for the message text in alerts.
#	[...] The _small system font_ (Lucida Grande Regular 11 pt) [...]
#	is also the default font for column headings in lists, for help tags,
#	and for small controls.
#
#	Note that the font for column headings (TkHeadingFont) is
#	_smaller_ than the default font.
#
#	There does not appear to be any recommendations for fixed-width fonts.
#
# X11:
#	"Classic" look used Helvetica bold for everything except
#	for entry widgets, which use Helvetica medium.
#	Most other toolkits use medium weight for all UI elements,
#	which is what we do now.
