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().

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.
