Detailed Description

A Gio::Icon that allows numbered emblems.

Gtk::NumerableIcon is a subclass of Gio::EmblemedIcon 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 StyleContext. See set_style_context().

Since gtkmm 3.0:

Deprecated:: No replacement available.

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy< Glib::RefPtr<StyleContext> > Gtk::NumerableIcon::property_style_context ( )

The style context to theme the icon appearance.

Returns: A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< Glib::RefPtr<StyleContext> > Gtk::NumerableIcon::property_style_context ( ) const

The style context to theme the icon appearance.

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

void Gtk::NumerableIcon::set_background_gicon ( const Glib::RefPtr< Gio::Icon > & icon )

Updates the icon to use icon as the base background image.

If icon is nullptr, 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 set_background_gicon() and set_background_icon_name() has always priority.

Since gtkmm 3.0:

Deprecated: 3.14

Parameters

icon	A Icon, or `nullptr`.

void Gtk::NumerableIcon::set_background_icon_name ( const Glib::ustring & 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 nullptr, self will go back using style information or default theming for its background image.

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

Since gtkmm 3.0:

Deprecated: 3.14

Parameters

icon_name An icon name, or nullptr.

void Gtk::NumerableIcon::set_count ( int 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 nullptr before rendering the number, i.e. the last method called between set_count() and set_label() has always priority.

Since gtkmm 3.0:

Deprecated: 3.14

Parameters

count A number between -99 and 99.

void Gtk::NumerableIcon::set_label ( const Glib::ustring & 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 set_label() and set_count() has always priority.

Since gtkmm 3.0:

Deprecated: 3.14

Parameters

label A short label, or nullptr.

void Gtk::NumerableIcon::set_style_context ( const Glib::RefPtr< StyleContext >& style )

Updates the icon to fetch theme information from the given Gtk::StyleContext.

Since gtkmm 3.0:

Deprecated: 3.14

Parameters

style A Gtk::StyleContext.
