# `tkinter.fontchooser` — Font selection dialog

Added in version 3.16.0a0 (unreleased).

Source code: Lib/tkinter/fontchooser.py

The `tkinter.fontchooser` module provides the `FontChooser` class as an interface to the native font selection dialog.

The font dialog is application-global: there is a single font dialog per Tcl interpreter, and all `FontChooser` instances configure the same dialog.

Depending on the platform, the dialog may be modal or modeless, so `show()` may return immediately. The selected font is not returned: it is passed as a `Font` object to the callback specified with the command option.

The dialog also generates two virtual events on the parent window (see the parent option):

`<<TkFontchooserVisibility>>`

  Generated when the dialog is shown or hidden. Query the visible option to tell which.

`<<TkFontchooserFontChanged>>`

  Generated when the selected font changes.

Nota

The command callback is the only reliable way to obtain the selected font. On some platforms the font option is not updated to the user’s choice.

class tkinter.fontchooser.FontChooser(master=None, **options)

  The class implementing the font selection dialog.

  master is the widget whose Tcl interpreter owns the dialog. If omitted, it defaults to parent if that is given, or to the default root window otherwise.

  The supported configuration options are:

  - parent — the window to which the dialog and its virtual events are related. It defaults to the main window; on macOS the dialog is shown as a sheet attached to it, rather than as a free-standing panel.

  - title — the title of the dialog.

  - font — the font that is currently selected in the dialog.

  - command — a callback that is called with a `Font` object wrapping the selected font when the user selects a font.

  - visible — whether the dialog is currently displayed (read-only).

  The font option accepts the forms supported by `tkinter.font.Font`.

  configure(**options)
  config(**options)

    Query or modify the options of the font dialog. With no arguments, return a dict of all option values. With a string argument, return the value of that option. Otherwise, set the given options.

  cget(option)

    Return the value of the given option of the font dialog.

  show()

    Display the font dialog. Depending on the platform, this method may return immediately or only once the dialog has been withdrawn.

  hide()

    Hide the font dialog if it is displayed.
