# `tkinter.font` — Tkinter font wrapper

Source code: Lib/tkinter/font.py

The `tkinter.font` module provides the `Font` class for creating and using named fonts.

The different font weights and slants are:

tkinter.font.NORMAL
tkinter.font.BOLD
tkinter.font.ITALIC
tkinter.font.ROMAN

class tkinter.font.Font(root=None, font=None, name=None, exists=False, **options)

  The `Font` class represents a named font. Font instances are given unique names and can be specified by their family, size, and style configuration. Named fonts are Tk’s method of creating and identifying fonts as a single object, rather than specifying a font by its attributes with each occurrence.

  > arguments:

  > > font - font specifier tuple (family, size, options)
  > > name - unique font name
  > > exists - self points to existing named font if true

  > additional keyword options (ignored if font is specified):

  > > family - font family i.e. Courier, Times
  > > size - font size
  > > If size is positive it is interpreted as size in points.
  > > If size is a negative number its absolute value is treated
  > > as size in pixels.
  > > weight - font emphasis (NORMAL, BOLD)
  > > slant - ROMAN, ITALIC
  > > underline - font underlining (0 - none, 1 - underline)
  > > overstrike - font strikeout (0 - none, 1 - strikeout)

  actual(option=None, displayof=None)

  metrics(*options, **kw)

    Return font-specific data. Options include:

    ascent - distance between baseline and highest point that a

      character of the font can occupy

    descent - distance between baseline and lowest point that a

      character of the font can occupy

    linespace - minimum vertical separation necessary between any two

      characters of the font that ensures no vertical overlap between lines.

    fixed - 1 if font is fixed-width else 0

tkinter.font.families(root=None, displayof=None)

  Return the different font families.

tkinter.font.names(root=None)

  Return the names of defined fonts.

tkinter.font.nametofont(name, root=None)
