1. wrap_TreeViewMappingFunc :: Maybe (Ptr (FunPtr C_TreeViewMappingFunc)) -> TreeViewMappingFunc_WithClosures -> C_TreeViewMappingFunc

   gi-gtk3	GI.Gtk.Callbacks

   Wrap a TreeViewMappingFunc into a C_TreeViewMappingFunc.

2. wrap_WidgetClassMapEventFieldCallback :: Maybe (Ptr (FunPtr C_WidgetClassMapEventFieldCallback)) -> WidgetClassMapEventFieldCallback -> C_WidgetClassMapEventFieldCallback

   gi-gtk3	GI.Gtk.Callbacks

   Wrap a WidgetClassMapEventFieldCallback into a C_WidgetClassMapEventFieldCallback.

3. wrap_WidgetClassMapFieldCallback :: Maybe (Ptr (FunPtr C_WidgetClassMapFieldCallback)) -> WidgetClassMapFieldCallback -> C_WidgetClassMapFieldCallback

   gi-gtk3	GI.Gtk.Callbacks

   Wrap a WidgetClassMapFieldCallback into a C_WidgetClassMapFieldCallback.

4. wrap_WidgetClassUnmapEventFieldCallback :: Maybe (Ptr (FunPtr C_WidgetClassUnmapEventFieldCallback)) -> WidgetClassUnmapEventFieldCallback -> C_WidgetClassUnmapEventFieldCallback

   gi-gtk3	GI.Gtk.Callbacks

   Wrap a WidgetClassUnmapEventFieldCallback into a C_WidgetClassUnmapEventFieldCallback.

5. wrap_WidgetClassUnmapFieldCallback :: Maybe (Ptr (FunPtr C_WidgetClassUnmapFieldCallback)) -> WidgetClassUnmapFieldCallback -> C_WidgetClassUnmapFieldCallback

6. RcTokenTypeBgPixmap :: RcTokenType

   gi-gtk3	GI.Gtk.Enums

   Deprecated

7. RcTokenTypePixmapPath :: RcTokenType

   gi-gtk3	GI.Gtk.Enums

   Deprecated

8. rcFindPixmapInPath :: (HasCallStack, MonadIO m, IsSettings a) => a -> Scanner -> Text -> m [Char]

   gi-gtk3	GI.Gtk.Functions

   Deprecated: (Since version 3.0)Use CssProvider instead.

9. fontChooserGetFontMap :: (HasCallStack, MonadIO m, IsFontChooser a) => a -> m (Maybe FontMap)

   gi-gtk3	GI.Gtk.Interfaces.FontChooser

   Gets the custom font map of this font chooser widget, or Nothing if it does not have one. Since: 3.18

10. fontChooserSetFontMap :: (HasCallStack, MonadIO m, IsFontChooser a, IsFontMap b) => a -> Maybe b -> m ()

    gi-gtk3	GI.Gtk.Interfaces.FontChooser

    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.

    C code

    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:

    context = gtk_widget_get_pango_context (label);
    pango_context_set_font_map (context, fontmap);
    

    Since: 3.18
