§Implementors

FontButton, FontChooserDialog, FontChooserWidget, FontChooser

Provided Methods§

source

fn font(&self) -> Option<GString>

👎Deprecated: Since 4.10

Gets the currently-selected font name.

Note that this can be a different string than what you set with set_font(), as the font chooser widget may normalize font names and thus return a string with a different structure. For example, “Helvetica Italic Bold 12” could be normalized to “Helvetica Bold Italic 12”.

Use Pango::FontDescription::equal() if you want to compare two font descriptions.

§Deprecated since 4.10

Use FontDialog and FontDialogButton instead

§Returns

A string with the name of the current font

source

fn font_desc(&self) -> Option<FontDescription>

👎Deprecated: Since 4.10

Gets the currently-selected font.

Note that this can be a different string than what you set with set_font(), as the font chooser widget may normalize font names and thus return a string with a different structure. For example, “Helvetica Italic Bold 12” could be normalized to “Helvetica Bold Italic 12”.

Use Pango::FontDescription::equal() if you want to compare two font descriptions.

§Deprecated since 4.10

Use FontDialog and FontDialogButton instead

§Returns

A pango::FontDescription for the current font

source

fn font_face(&self) -> Option<FontFace>

👎Deprecated: Since 4.10

Gets the pango::FontFace representing the selected font group details (i.e. family, slant, weight, width, etc).

If the selected font is not installed, returns None.

§Deprecated since 4.10

Use FontDialog and FontDialogButton instead

§Returns

A pango::FontFace representing the selected font group details

source

fn font_family(&self) -> Option<FontFamily>

👎Deprecated: Since 4.10

Gets the pango::FontFamily representing the selected font family.

Font families are a collection of font faces.

If the selected font is not installed, returns None.

§Deprecated since 4.10

Use FontDialog and FontDialogButton instead

§Returns

A pango::FontFamily representing the selected font family

source

fn font_features(&self) -> GString

👎Deprecated: Since 4.10

Gets the currently-selected font features.

The format of the returned string is compatible with the CSS font-feature-settings property. It can be passed to Pango::AttrFontFeatures::new().

§Deprecated since 4.10

Use FontDialog and FontDialogButton instead

§Returns

the currently selected font features

source

fn font_map(&self) -> Option<FontMap>

👎Deprecated: Since 4.10

Gets the custom font map of this font chooser widget, or None if it does not have one.

§Deprecated since 4.10

Use FontDialog and FontDialogButton instead

§Returns

a pango::FontMap

source

fn font_size(&self) -> i32

👎Deprecated: Since 4.10

The selected font size.

§Deprecated since 4.10

Use FontDialog and FontDialogButton instead

§Returns

A n integer representing the selected font size, or -1 if no font size is selected.

source

fn language(&self) -> GString

👎Deprecated: Since 4.10

Gets the language that is used for font features.

§Deprecated since 4.10

Use FontDialog and FontDialogButton instead

§Returns

the currently selected language

source

fn level(&self) -> FontChooserLevel

👎Deprecated: Since 4.10

Returns the current level of granularity for selecting fonts.

§Deprecated since 4.10

Use FontDialog and FontDialogButton instead

§Returns

the current granularity level

source

fn preview_text(&self) -> GString

👎Deprecated: Since 4.10

Gets the text displayed in the preview area.

§Deprecated since 4.10

Use FontDialog and FontDialogButton instead

§Returns

the text displayed in the preview area

source

fn shows_preview_entry(&self) -> bool

👎Deprecated: Since 4.10

Returns whether the preview entry is shown or not.

§Deprecated since 4.10

Use FontDialog and FontDialogButton instead

§Returns

true if the preview entry is shown or false if it is hidden.

source

fn set_filter_func<P: Fn(&FontFamily, &FontFace) -> bool + 'static>( &self, filter: P )

👎Deprecated: Since 4.10

Adds a filter function that decides which fonts to display in the font chooser.

§Deprecated since 4.10

Use FontDialog and FontDialogButton instead

§filter

a GtkFontFilterFunc

source

fn set_font(&self, fontname: &str)

👎Deprecated: Since 4.10

Sets the currently-selected font.

§Deprecated since 4.10

Use FontDialog and FontDialogButton instead

§fontname

a font name like “Helvetica 12” or “Times Bold 18”

source

fn set_font_desc(&self, font_desc: &FontDescription)

👎Deprecated: Since 4.10

Sets the currently-selected font from @font_desc.

§Deprecated since 4.10

Use FontDialog and FontDialogButton instead

§font_desc

a pango::FontDescription

source

fn set_font_map(&self, fontmap: Option<&impl IsA<FontMap>>)

👎Deprecated: Since 4.10

Sets a custom font map to use for this font chooser widget.

A custom font map can be used to present application-specific fonts instead of or in addition to the normal system fonts.

⚠️ The following code is in c ⚠️

FcConfig *config;
PangoFontMap *fontmap;

config = FcInitLoadConfigAndFonts ();
FcConfigAppFontAddFile (config, my_app_font_file);

fontmap = pango_cairo_font_map_new_for_font_type (CAIRO_FONT_TYPE_FT);
pango_fc_font_map_set_config (PANGO_FC_FONT_MAP (fontmap), config);

gtk_font_chooser_set_font_map (font_chooser, fontmap);

Note that other GTK widgets will only be able to use the application-specific font if it is present in the font map they use:

⚠️ The following code is in c ⚠️

context = gtk_widget_get_pango_context (label);
pango_context_set_font_map (context, fontmap);
§Deprecated since 4.10

Use FontDialog and FontDialogButton instead

§fontmap
