GtkIconFactory *
gtk_style_provider_get_icon_factory (GtkStyleProvider *provider,
                                     GtkWidgetPath *path);

gtk_style_provider_get_icon_factory has been deprecated since version 3.8 and should not be used in newly-written code.

Will always return NULL for all GTK-provided style providers.

Returns the GtkIconFactory defined to be in use for path , or NULL if none is defined.

Parameters

provider

a GtkStyleProvider

path

GtkWidgetPath to query

Returns

The icon factory to use for path , or NULL.

gtk_style_provider_get_style ()

GtkStyleProperties *
gtk_style_provider_get_style (GtkStyleProvider *provider,
                              GtkWidgetPath *path);

gtk_style_provider_get_style has been deprecated since version 3.8 and should not be used in newly-written code.

Will always return NULL for all GTK-provided style providers as the interface cannot correctly work the way CSS is specified.

Returns the style settings affecting a widget defined by path , or NULL if provider doesn’t contemplate styling path .

Parameters

provider

a GtkStyleProvider

                                       GParamSpec *pspec,
                                       GValue *value);

Looks up a widget style property as defined by provider for the widget represented by path .

Types and Values

struct GtkStyleProviderIface

struct GtkStyleProviderIface {
  GtkStyleProperties * (* get_style) (GtkStyleProvider *provider,
                                      GtkWidgetPath    *path);

  gboolean (* get_style_property) (GtkStyleProvider *provider,
                                   GtkWidgetPath    *path,
                                   GtkStateFlags     state,
                                   GParamSpec       *pspec,
                                   GValue           *value);

  GtkIconFactory * (* get_icon_factory) (GtkStyleProvider *provider,
					 GtkWidgetPath    *path);
};

Members

get_style ()

Gets a set of style information that applies to a widget path.

get_style_property ()

Gets the value of a widget style property that applies to a widget path.

get_icon_factory ()

Gets the icon factory that applies to a widget path.

GtkStyleProvider

typedef struct _GtkStyleProvider GtkStyleProvider;

GTK_STYLE_PROVIDER_PRIORITY_FALLBACK

#define GTK_STYLE_PROVIDER_PRIORITY_FALLBACK      1

The priority used for default style information that is used in the absence of themes.

Note that this is not very useful for providing default styling for custom style classes - themes are likely to override styling provided at this priority with catch-all * {...} rules.

GTK_STYLE_PROVIDER_PRIORITY_THEME

#define GTK_STYLE_PROVIDER_PRIORITY_THEME     200

The priority used for style information provided by themes.

GTK_STYLE_PROVIDER_PRIORITY_SETTINGS

#define GTK_STYLE_PROVIDER_PRIORITY_SETTINGS    400

The priority used for style information provided via GtkSettings.

This priority is higher than GTK_STYLE_PROVIDER_PRIORITY_THEME to let settings override themes.

GTK_STYLE_PROVIDER_PRIORITY_APPLICATION

#define GTK_STYLE_PROVIDER_PRIORITY_APPLICATION 600

A priority that can be used when adding a GtkStyleProvider for application-specific style information.

GTK_STYLE_PROVIDER_PRIORITY_USER

#define GTK_STYLE_PROVIDER_PRIORITY_USER        800

The priority used for the style information from XDG_CONFIG_HOME/gtk-3.0/gtk.css.

You should not use priorities higher than this, to give the user the last word.
