Retrieves the name of the currently selected font. This name includes style and size information as well. If you want to render something with the font, use this string with fontDescriptionFromString . If you’re interested in peeking certain values (family name, style, size, weight) just query these properties from the FontDescription object.

The name of the currently selected font.

Since: 2.4

clearFontButtonFontName :: (MonadIO m, IsFontButton o) => o -> m () Source #

clear #fontName

constructFontButtonFontName :: (IsFontButton o, MonadIO m) => Text -> m (GValueConstruct o) Source #

Construct a GValueConstruct with valid value for the “font-name” property. This is rarely needed directly, but it is used by new.

getFontButtonFontName :: (MonadIO m, IsFontButton o) => o -> m Text Source #

Get the value of the “font-name” property. When overloading is enabled, this is equivalent to

get fontButton #fontName

setFontButtonFontName :: (MonadIO m, IsFontButton o) => o -> Text -> m () Source #

Set the value of the “font-name” property. When overloading is enabled, this is equivalent to

set fontButton [ #fontName := value ]

showSize

If this property is set to True, the selected font size will be shown in the label. For a more WYSIWYG way to show the selected size, see the useSize property.

Since: 2.4

Since: 2.4

constructFontButtonUseFont :: (IsFontButton o, MonadIO m) => Bool -> m (GValueConstruct o) Source #

Construct a GValueConstruct with valid value for the “use-font” property. This is rarely needed directly, but it is used by new.

Signals

fontSet

type C_FontButtonFontSetCallback = Ptr () -> Ptr () -> IO () Source #

Type for the callback on the (unwrapped) C side.

type FontButtonFontSetCallback = IO () Source #

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

Note that this signal is only emitted when the user changes the font. If you need to react to programmatic font changes as well, use the notify[font](#g:signal:font) signal.

Since: 2.4

afterFontButtonFontSet :: (IsFontButton a, MonadIO m) => a -> FontButtonFontSetCallback -> m SignalHandlerId Source #

Connect a signal handler for the fontSet signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after fontButton #fontSet callback

onFontButtonFontSet :: (IsFontButton a, MonadIO m) => a -> FontButtonFontSetCallback -> m SignalHandlerId Source #

Connect a signal handler for the fontSet signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on fontButton #fontSet callback
