## Member Function Documentation

TextDirection Gtk::IconSource::get_direction | ( |  | ) | const

| Obtains the text direction this icon source applies to. The return value is only useful/meaningful if the text direction is not wildcarded. Returns: Text direction this source matches.

bool Gtk::IconSource::get_direction_wildcarded | ( |  | ) | const

| Gets the value set by gtk_icon_source_set_direction_wildcarded(). Returns: `true` if this icon source is a base for any text direction variant.

Glib::ustring Gtk::IconSource::get_filename | ( |  | ) | const

| Retrieves the source filename, or `0` if none is set. The filename is not a copy, and should not be modified or expected to persist beyond the lifetime of the icon source. Returns: Image filename. This string must not be modified or freed.

Glib::ustring Gtk::IconSource::get_icon_name | ( |  | ) | const

| Retrieves the source icon name, or `0` if none is set. The icon_name is not a copy, and should not be modified or expected to persist beyond the lifetime of the icon source. Returns: Icon name. This string must not be modified or freed.

Glib::RefPtr<const Gdk::Pixbuf> Gtk::IconSource::get_pixbuf | ( |  | ) | const

| Retrieves the source pixbuf, or `0` if none is set. In addition, if a filename source is in use, this function in some cases will return the pixbuf from loaded from the filename. This is, for example, true for the GtkIconSource passed to the GtkStyle::render_icon() virtual function. The reference count on the pixbuf is not incremented. Returns: Source pixbuf.

Glib::RefPtr<Gdk::Pixbuf> Gtk::IconSource::get_pixbuf | ( |  | ) |

| Retrieves the source pixbuf, or `0` if none is set. In addition, if a filename source is in use, this function in some cases will return the pixbuf from loaded from the filename. This is, for example, true for the GtkIconSource passed to the GtkStyle::render_icon() virtual function. The reference count on the pixbuf is not incremented. Returns: Source pixbuf.

IconSize Gtk::IconSource::get_size | ( |  | ) | const

| Obtains the icon size this source applies to. The return value is only useful/meaningful if the icon size is not wildcarded. Returns: Icon size this source matches.

bool Gtk::IconSource::get_size_wildcarded | ( |  | ) | const

| Gets the value set by gtk_icon_source_set_size_wildcarded(). Returns: `true` if this icon source is a base for any icon size variant.

Gtk::StateType Gtk::IconSource::get_state | ( |  | ) | const

| Obtains the widget state this icon source applies to. The return value is only useful/meaningful if the widget state is not wildcarded. Returns: Widget state this source matches.

bool Gtk::IconSource::get_state_wildcarded | ( |  | ) | const

| Gets the value set by gtk_icon_source_set_state_wildcarded(). Returns: `true` if this icon source is a base for any widget state variant.

const GtkIconSource* Gtk::IconSource::gobj | ( |  | ) | const`[inline]`

| Provides access to the underlying C instance.

GtkIconSource* Gtk::IconSource::gobj | ( |  | ) | `[inline]`

| Provides access to the underlying C instance.

GtkIconSource* Gtk::IconSource::gobj_copy | ( |  | ) | const

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

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

void Gtk::IconSource::set_direction | ( | TextDirection | direction | ) |

  | Sets the text direction this icon source is intended to be used with. Setting the text direction on an icon source makes no difference if the text direction is wildcarded. Therefore, you should usually call gtk_icon_source_set_direction_wildcarded() to un-wildcard it in addition to calling this function. Parameters:
  | direction | Text direction this source applies to.

void Gtk::IconSource::set_direction_wildcarded | ( | bool | setting = `true` | ) |

  | If the text direction is wildcarded, this source can be used as the base image for an icon in any Gtk::TextDirection. If the text direction is not wildcarded, then the text direction the icon source applies to should be set with gtk_icon_source_set_direction(), and the icon source will only be used with that text direction. Gtk::IconSet prefers non-wildcarded sources (exact matches) over wildcarded sources, and will use an exact match when possible. Parameters:
  | setting | `true` to wildcard the text direction.

void Gtk::IconSource::set_filename | ( | const Glib::ustring& | filename | ) |

  | Sets the name of an image file to use as a base image when creating icon variants for Gtk::IconSet. The filename must be absolute. Parameters:
  | filename | Image file to use.

void Gtk::IconSource::set_icon_name | ( | const Glib::ustring& | icon_name | ) |

  | Sets the name of an icon to look up in the current icon theme to use as a base image when creating icon variants for Gtk::IconSet. Parameters:
  | icon_name | Name of icon to use.

void Gtk::IconSource::set_pixbuf | ( | const Glib::RefPtr<Gdk::Pixbuf>& | pixbuf | ) |

  | Sets a pixbuf to use as a base image when creating icon variants for Gtk::IconSet. Parameters:
  | pixbuf | Pixbuf to use as a source.

void Gtk::IconSource::set_size | ( | IconSize | size | ) |

  | Sets the icon size this icon source is intended to be used with. Setting the icon size on an icon source makes no difference if the size is wildcarded. Therefore, you should usually call gtk_icon_source_set_size_wildcarded() to un-wildcard it in addition to calling this function. Parameters:
  | size | Icon size this source applies to.

void Gtk::IconSource::set_size_wildcarded | ( | bool | setting = `true` | ) |

  | If the icon size is wildcarded, this source can be used as the base image for an icon of any size. If the size is not wildcarded, then the size the source applies to should be set with gtk_icon_source_set_size() and the icon source will only be used with that specific size. Gtk::IconSet prefers non-wildcarded sources (exact matches) over wildcarded sources, and will use an exact match when possible. Gtk::IconSet will normally scale wildcarded source images to produce an appropriate icon at a given size, but will not change the size of source images that match exactly. Parameters:
  | setting | `true` to wildcard the widget state.

void Gtk::IconSource::set_state | ( | Gtk::StateType | state | ) |

  | Sets the widget state this icon source is intended to be used with. Setting the widget state on an icon source makes no difference if the state is wildcarded. Therefore, you should usually call gtk_icon_source_set_state_wildcarded() to un-wildcard it in addition to calling this function. Parameters:
  | state | Widget state this source applies to.

void Gtk::IconSource::set_state_wildcarded | ( | bool | setting = `true` | ) |

  | If the widget state is wildcarded, this source can be used as the base image for an icon in any Gtk::StateType. If the widget state is not wildcarded, then the state the source applies to should be set with gtk_icon_source_set_state() and the icon source will only be used with that specific state. Gtk::IconSet prefers non-wildcarded sources (exact matches) over wildcarded sources, and will use an exact match when possible. Gtk::IconSet will normally transform wildcarded source images to produce an appropriate icon for a given state, for example lightening an image on prelight, but will not modify source images that match exactly. Parameters:
  | setting | `true` to wildcard the widget state.

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

## Friends And Related Function Documentation

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

  | Parameters:
  | lhs | The left-hand side
  | rhs | The right-hand side

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

  | 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.
