## Member Function Documentation

void Gtk::IconSet::add_source | ( | const IconSource& | source | ) |

Icon sets have a list of Gtk::IconSource, which they use as base icons for rendering icons in different states and sizes.

Icons are scaled, made to look insensitive, etc. in gtk_icon_set_render_icon(), but Gtk::IconSet needs base images to work with. The base images and when to use them are described by a Gtk::IconSource.

This function copies source , so you can reuse the same source immediately without affecting the icon set.

An example of when you'd use this function: a web browser's "Back to Previous Page" icon might point in a different direction in Hebrew and in English; it might look different when insensitive; and it might change size depending on toolbar mode (small/large icons). So a single icon set would contain all those variants of the icon, and you might add a separate source for each one.

You should nearly always add a "default" icon source with all fields wildcarded, which will be used as a fallback if no more specific source matches. Gtk::IconSet always prefers more specific icon sources to more generic icon sources. The order in which you add the sources to the icon set does not matter.

gtk_icon_set_new_from_pixbuf() creates a new icon set with a default icon source based on the given pixbuf.

Parameters:

  | source | A Gtk::IconSource.

IconSet Gtk::IconSet::copy | ( |  | ) | const

Copies icon_set by value.

Returns:
  A new Gtk::IconSet identical to the first.

Glib::ArrayHandle<IconSize> Gtk::IconSet::get_sizes | ( |  | ) | const

const GtkIconSet* Gtk::IconSet::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C instance.

GtkIconSet* Gtk::IconSet::gobj | ( |  | ) | `[inline]`

Provides access to the underlying C instance.

GtkIconSet* Gtk::IconSet::gobj_copy | ( |  | ) | const

Provides access to the underlying C instance. The caller is responsible for freeing it. Use when directly setting fields in structs.

static IconSet Gtk::IconSet::lookup_default | ( | const Gtk::StockID& | stock_id | ) | `[static]`

IconSet& Gtk::IconSet::operator= | ( | const IconSet& | other | ) |

Glib::RefPtr<Gdk::Pixbuf> Gtk::IconSet::render_icon | ( | const Glib::RefPtr<Style>& | style,
|  | TextDirection | direction,
|  | Gtk::StateType | state,
|  | IconSize | size,
|  | Widget& | widget,
|  | const Glib::ustring & | detail |
| ) |  |  |

Renders an icon using Gtk::Style::render_icon().

In most cases, Gtk::Widget::render_icon() is better, since it automatically provides most of the arguments from the current widget settings. This function never returns `0`; if the icon can't be rendered (perhaps because an image file fails to load), a default "missing image" icon will be returned instead.

Parameters:

  | style | A Gtk::Style associated with widget , or `0`.
  | direction | Text direction.
  | state | Widget state.
  | size | Icon size. A size of (GtkIconSize)-1 means render at the size of the source and don't scale.
  | widget | Widget that will display the icon, or `0`. The only use that is typically made of this is to determine the appropriate Gdk::Screen.
  | detail | Detail to pass to the theme engine, or `0`. Note that passing a detail of anything but `0` will disable caching.

Returns:
  A Gdk::Pixbuf to be displayed.

void Gtk::IconSet::swap | ( | IconSet& | other | ) |

## Friends And Related Function Documentation

void swap | ( | IconSet& | lhs,
|  | IconSet& | rhs |
| ) |  |  | `[related]`

Parameters:

  | lhs | The left-hand side

Parameters:

  | rhs | The right-hand side

Gtk::IconSet wrap | ( | GtkIconSet * | object,
|  | bool | take_copy = `false` |
| ) |  |  | `[related]`

A Glib::wrap() method for this object.

Parameters:

  | object | The C instance.
  | take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:
  A C++ instance that wraps this C instance.
