## Includes

    #include <gtk/gtk.h>

## 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()`.

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.

context | a GtkStyleContext |

#### Returns

a new GIcon.

### gtk_numerable_icon_get_background_gicon ()

    GIcon *
    gtk_numerable_icon_get_background_gicon
                                   (GtkNumerableIcon *self);

`gtk_numerable_icon_get_background_gicon` has been deprecated since version 3.14 and should not be used in newly-written code.

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.

#### Parameters

self | a GtkNumerableIcon |

#### Returns

a GIcon, or `NULL`.

[nullable][transfer none]

Since: 3.0

### gtk_numerable_icon_set_background_gicon ()

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

`gtk_numerable_icon_set_background_gicon` has been deprecated since version 3.14 and should not be used in newly-written code.

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.

#### Parameters

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);

`gtk_numerable_icon_get_background_icon_name` has been deprecated since version 3.14 and should not be used in newly-written code.

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

#### Parameters

self | a GtkNumerableIcon |

#### Returns

an icon name, or `NULL`.

[nullable]

Since: 3.0

### gtk_numerable_icon_set_background_icon_name ()

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

`gtk_numerable_icon_set_background_icon_name` has been deprecated since version 3.14 and should not be used in newly-written code.

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.

#### Parameters

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);

`gtk_numerable_icon_get_count` has been deprecated since version 3.14 and should not be used in newly-written code.

Returns the value currently displayed by `self` .

#### Parameters

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);

`gtk_numerable_icon_set_count` has been deprecated since version 3.14 and should not be used in newly-written code.

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.

#### Parameters

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);

`gtk_numerable_icon_get_label` has been deprecated since version 3.14 and should not be used in newly-written code.

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

#### Parameters

self | a GtkNumerableIcon |

#### Returns

the currently displayed label.

[nullable]

Since: 3.0

### gtk_numerable_icon_set_label ()

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

`gtk_numerable_icon_set_label` has been deprecated since version 3.14 and should not be used in newly-written code.

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.

#### Parameters

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);

`gtk_numerable_icon_get_style_context` has been deprecated since version 3.14 and should not be used in newly-written code.

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

#### Parameters

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.

[nullable][transfer none]

Since: 3.0

### gtk_numerable_icon_set_style_context ()

    void
    gtk_numerable_icon_set_style_context (GtkNumerableIcon *self,

`gtk_numerable_icon_set_style_context` has been deprecated since version 3.14 and should not be used in newly-written code.

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

#### Parameters

self | a GtkNumerableIcon |
style | a GtkStyleContext |
