FontDialog#

Added in version 4.10.

class FontDialog(**properties: Any)#

Superclasses: Object

A GtkFontDialog object collects the arguments that are needed to present a font chooser dialog to the user, such as a title for the dialog and whether it should be modal.

The dialog is shown with the choose_font function or its variants.

See FontDialogButton for a convenient control that uses GtkFontDialog and presents the results.

Constructors#

class FontDialog
classmethod new() → FontDialog#

Creates a new GtkFontDialog object.

Added in version 4.10.

Methods#

class FontDialog
choose_face(parent: Window | None = None, initial_value: FontFace | None = None, cancellable: Cancellable | None = None, callback: Callable[[...], None] | None = None, *user_data: Any) → None#

This function initiates a font selection operation by presenting a dialog to the user for selecting a font face (i.e. a font family and style, but not a specific font size).

Added in version 4.10.

Parameters:

  • parent – the parent GtkWindow

  • initial_value – the initial value

  • cancellable – a GCancellable to cancel the operation

  • callback – a callback to call when the operation is complete

  • user_data – data to pass to callback

choose_face_finish(result: AsyncResult) → FontFace | None#

Finishes the choose_face call and returns the resulting font face.

Added in version 4.10.

Parameters:

result – a GAsyncResult

choose_family(parent: Window | None = None, initial_value: FontFamily | None = None, cancellable: Cancellable | None = None, callback: Callable[[...], None] | None = None, *user_data: Any) → None#

This function initiates a font selection operation by presenting a dialog to the user for selecting a font family.

Added in version 4.10.

Parameters:

  • parent – the parent GtkWindow

  • initial_value – the initial value

  • cancellable – a GCancellable to cancel the operation

  • callback – a callback to call when the operation is complete

  • user_data – data to pass to callback

choose_family_finish(result: AsyncResult) → FontFamily | None#

Finishes the choose_family call and returns the resulting family.

This function never returns an error. If the operation is not finished successfully, the value passed as initial_value to choose_family is returned.

Added in version 4.10.

Parameters:

result – a GAsyncResult

choose_font(parent: Window | None = None, initial_value: FontDescription | None = None, cancellable: Cancellable | None = None, callback: Callable[[...], None] | None = None, *user_data: Any) → None#

This function initiates a font selection operation by presenting a dialog to the user for selecting a font.

If you want to let the user select font features as well, use choose_font_and_features instead.

Added in version 4.10.

Parameters:

  • parent – the parent GtkWindow

  • initial_value – the font to select initially

  • cancellable – a GCancellable to cancel the operation

  • callback – a callback to call when the operation is complete

  • user_data – data to pass to callback

choose_font_and_features(parent: Window | None = None, initial_value: FontDescription | None = None, cancellable: Cancellable | None = None, callback: Callable[[...], None] | None = None, *user_data: Any) → None#

This function initiates a font selection operation by presenting a dialog to the user for selecting a font and font features.

Font features affect how the font is rendered, for example enabling glyph variants or ligatures.

Added in version 4.10.

Parameters:

  • parent – the parent GtkWindow

  • initial_value – the font to select initially

  • cancellable – a GCancellable to cancel the operation

  • callback – a callback to call when the operation is complete

  • user_data – data to pass to callback

choose_font_and_features_finish(result: AsyncResult) → tuple[bool, FontDescription, str, Language]#

Finishes the choose_font_and_features call and returns the resulting font description and font features.

result – a GAsyncResult

choose_font_finish(result: AsyncResult) → FontDescription | None#

Finishes the choose_font call and returns the resulting font description.

Added in version 4.10.
