This class is used for determining the pixel_width and pixel_height of strings when the width and/or height is not supplied with the object. This class also loads and defines a default font when an object does not directly specify a font. This module requires that each GUI Binding implement the following methods:

• Lfont.supported_font_names()
• Lfont.get_text_width(ltext, lfont) - needed to determine the size requirements for each font
• Lfont.get_text_height(ltext, lfont) - needed to determine the size requirements for each font

This returns the name of the default font. This is called by Lfont.default_font(). If a default_font is specified in a theme, it will take precedence over this method. The default font name is Locana_gui::default_font_name() to let the GUI Binding determine the default font.

This returns the size of the default font. This is called by Lfont.default_font(). If a default_font is specified in a theme, it will take precedence over this method. The default font size is Locana_gui::default_font_size() to let the GUI Binding determine the default font size.

Returns the default font when a font is not specified with an object. It calls Lfont.default_font_name and Lfont.default_font_size to determine the default font. If a default_font can is specified in a theme, it will take precedence over this method.

Returns an array of supported font names.

This always returns an Lfont object. If a Lfont object already exists for lfont, it re-uses it. If not, it creates and returns a new Lfont object.

• lfont - an array of [font_name, font_size, font_style], an Lfont object, or the symbol of an already created Lfont object.

Creates a new font. Where font is an array of {name, size, style]:

• lfont - an array of [font_name, font_size, font_style] where
  • font_name can be symbol or string
  • font_size is a number or nil/0 for the default size
  • font_style is a symbol (:bold, :italic, :underline) or an array of these symbols
