# Attributes

fontButtonTitle :: FontButtonClass self => Attr self String

The title of the font selection dialog.

Default value: "Pick a Font"

fontButtonFontName :: FontButtonClass self => Attr self String

The name of the currently selected font.

Default value: "Sans 12"

fontButtonUseFont :: FontButtonClass self => Attr self Bool

If this property is set to `True`, the label will be drawn in the selected font.

Default value: `False`

fontButtonUseSize :: FontButtonClass self => Attr self Bool

# Signals

onFontSet :: FontButtonClass self => self -> IO () -> IO (ConnectId self)

The `fontSet` signal is emitted when the user selects a font. When handling this signal, use `fontButtonGetFontName` to find out which font was just selected.

afterFontSet :: FontButtonClass self => self -> IO () -> IO (ConnectId self)

The `fontSet` signal is emitted when the user selects a font. When handling this signal, use `fontButtonGetFontName` to find out which font was just selected.
