## Description

GtkNumerableIcon is a subclass of GEmblemedIcon that can show a number or short string as an emblem. The number can be overlayed on top of another emblem, if desired.

It supports theming by taking font and color information from a provided GtkStyleContext; see `gtk_numerable_icon_set_style_context()`.

### struct GtkNumerableIcon

    struct GtkNumerableIcon;

### gtk_numerable_icon_new ()

    GIcon *             gtk_numerable_icon_new              (GIcon *base_icon);

Creates a new unthemed GtkNumerableIcon.

`base_icon` : | a GIcon to overlay on
Returns : | a new GIcon. [transfer full]

Since 3.0

### gtk_numerable_icon_new_with_style_context ()

    GIcon *             gtk_numerable_icon_new_with_style_context
                                                            (GIcon *base_icon,
                                                             GtkStyleContext *context);

Creates a new GtkNumerableIcon which will themed according to the passed GtkStyleContext. This is a convenience constructor that calls `gtk_numerable_icon_set_style_context()` internally.

`base_icon` : | a GIcon to overlay on
`context` : | a GtkStyleContext
Returns : | a new GIcon. [transfer full]

Since 3.0

### gtk_numerable_icon_get_background_gicon ()

    GIcon *             gtk_numerable_icon_get_background_gicon
                                                            (GtkNumerableIcon *self);

Returns the GIcon that was set as the base background image, or `NULL` if there's none. The caller of this function does not own a reference to the returned GIcon.

`self` : | a GtkNumerableIcon
Returns : | a GIcon, or `NULL`. [transfer none]

Since 3.0

### gtk_numerable_icon_set_background_gicon ()

    void                gtk_numerable_icon_set_background_gicon
                                                            (GtkNumerableIcon *self,
                                                             GIcon *icon);

Updates the icon to use `icon` as the base background image. If `icon` is `NULL`, `self` will go back using style information or default theming for its background image.

If this method is called and an icon name was already set as background for the icon, `icon` will be used, i.e. the last method called between `gtk_numerable_icon_set_background_gicon()` and `gtk_numerable_icon_set_background_icon_name()` has always priority.

`self` : | a GtkNumerableIcon
`icon` : | a GIcon, or `NULL`. [allow-none]

Since 3.0

### gtk_numerable_icon_get_background_icon_name ()

    const gchar *       gtk_numerable_icon_get_background_icon_name
                                                            (GtkNumerableIcon *self);

Returns the icon name used as the base background image, or `NULL` if there's none.

`self` : | a GtkNumerableIcon
Returns : | an icon name, or `NULL`

Since 3.0

### gtk_numerable_icon_set_background_icon_name ()

    void                gtk_numerable_icon_set_background_icon_name
                                                            (GtkNumerableIcon *self,
                                                             const gchar *icon_name);

Updates the icon to use the icon named `icon_name` from the current icon theme as the base background image. If `icon_name` is `NULL`, `self` will go back using style information or default theming for its background image.

If this method is called and a GIcon was already set as background for the icon, `icon_name` will be used, i.e. the last method called between `gtk_numerable_icon_set_background_icon_name()` and `gtk_numerable_icon_set_background_gicon()` has always priority.

`self` : | a GtkNumerableIcon
`icon_name` : | an icon name, or `NULL`. [allow-none]

Since 3.0

### gtk_numerable_icon_get_count ()

    gint                gtk_numerable_icon_get_count        (GtkNumerableIcon *self);

Returns the value currently displayed by `self`.

`self` : | a GtkNumerableIcon
Returns : | the currently displayed value

Since 3.0

### gtk_numerable_icon_set_count ()

    void                gtk_numerable_icon_set_count        (GtkNumerableIcon *self,
                                                             gint count);

Sets the currently displayed value of `self` to `count`.

The numeric value is always clamped to make it two digits, i.e. between -99 and 99. Setting a count of zero removes the emblem. If this method is called, and a label was already set on the icon, it will automatically be reset to `NULL` before rendering the number, i.e. the last method called between `gtk_numerable_icon_set_count()` and `gtk_numerable_icon_set_label()` has always priority.

`self` : | a GtkNumerableIcon
`count` : | a number between -99 and 99

Since 3.0

### gtk_numerable_icon_get_label ()

    const gchar *       gtk_numerable_icon_get_label        (GtkNumerableIcon *self);

Returns the currently displayed label of the icon, or `NULL`.

`self` : | a GtkNumerableIcon
Returns : | the currently displayed label

Since 3.0

### gtk_numerable_icon_set_label ()

    void                gtk_numerable_icon_set_label        (GtkNumerableIcon *self,
                                                             const gchar *label);

Sets the currently displayed value of `self` to the string in `label`. Setting an empty label removes the emblem.

Note that this is meant for displaying short labels, such as roman numbers, or single letters. For roman numbers, consider using the Unicode characters U+2160 - U+217F. Strings longer than two characters will likely not be rendered very well.

If this method is called, and a number was already set on the icon, it will automatically be reset to zero before rendering the label, i.e. the last method called between `gtk_numerable_icon_set_label()` and `gtk_numerable_icon_set_count()` has always priority.

`self` : | a GtkNumerableIcon
`label` : | a short label, or `NULL`. [allow-none]

Since 3.0

### gtk_numerable_icon_get_style_context ()

    GtkStyleContext *   gtk_numerable_icon_get_style_context
                                                            (GtkNumerableIcon *self);

Returns the GtkStyleContext used by the icon for theming, or `NULL` if there's none.

`self` : | a GtkNumerableIcon
Returns : | a GtkStyleContext, or `NULL`. This object is internal to GTK+ and should not be unreffed. Use `g_object_ref()` if you want to keep it around. [transfer none]

Since 3.0

### gtk_numerable_icon_set_style_context ()

    void                gtk_numerable_icon_set_style_context
                                                            (GtkNumerableIcon *self,
                                                             GtkStyleContext *style);

Updates the icon to fetch theme information from the given GtkStyleContext.

`self` : | a GtkNumerableIcon
`style` : | a GtkStyleContext

Since 3.0
