A widget displaying an image.
The Gtk::Image widget displays an image. Various kinds of object can be displayed as an image; most typically, you would load a Gdk::Texture (which implements Gdk::Paintable) from a file, and then display that.
Gtk::Image displays its image as an icon, with a size that is determined by the application. See Gtk::Picture if you want to show an image at its actual size.
The Image widget looks like this:
 
| 
 | noexcept | 
| 
 | delete | 
| 
 | overridenoexcept | 
| Gtk::Image::Image | ( | ) | 
| 
 | explicit | 
Creates an Image widget displaying the file filename.
If the file isn't found or can't be loaded, the resulting Gtk::Image will display a "broken image" icon.
If you need to detect failures to load the file, use Gdk::Pixbuf::create_from_file() to load the file yourself, then create the GtkImage from the pixbuf.
The storage type (get_storage_type()) of the returned image is not defined. It will be whatever is appropriate for displaying the file.
| 
 | explicit | 
Creates a new Image widget displaying pixbuf.
Note that this just creates an GtkImage from the pixbuf. The Gtk::Image created will not react to state changes. Should you want that, you should use the default constructor and set_from_icon_name().
| 
 | explicit | 
Creates a new Gtk::Image displaying paintable.
The Gtk::Image will track changes to the paintable and update its size and contents in response to it.
| paintable | A Gdk::Paintable, or an emtpy Glib::RefPtr. | 
| 
 | explicit | 
Creates a Gtk::Image displaying an icon from the current icon theme. 
If the icon name isn’t known, a “broken image” icon will be displayed instead. If the current icon theme is changed, the icon will be updated appropriately.
| icon | An icon. | 
| void Gtk::Image::clear | ( | ) | 
Resets the image to be empty.
| Glib::RefPtr< Gio::Icon > Gtk::Image::get_gicon | ( | ) | 
Gets the Gio::Icon being displayed by the Gtk::Image. 
The storage type of the image must be Gtk::Image::Type::EMPTY or Gtk::Image::Type::GICON (see get_storage_type()). The caller of this function does not own a reference to the returned Gio::Icon.
Gio::Icon. | Glib::RefPtr< const Gio::Icon > Gtk::Image::get_gicon | ( | ) | const | 
Gets the Gio::Icon being displayed by the Gtk::Image. 
The storage type of the image must be Gtk::Image::Type::EMPTY or Gtk::Image::Type::GICON (see get_storage_type()). The caller of this function does not own a reference to the returned Gio::Icon.
Gio::Icon. | Glib::ustring Gtk::Image::get_icon_name | ( | ) | const | 
Gets the icon name and size being displayed by the Gtk::Image. 
The storage type of the image must be Gtk::Image::Type::EMPTY or Gtk::Image::Type::ICON_NAME (see get_storage_type()). The returned string is owned by the Gtk::Image and should not be freed.
| IconSize Gtk::Image::get_icon_size | ( | ) | const | 
Gets the icon size used by the image when rendering icons.
| Glib::RefPtr< Gdk::Paintable > Gtk::Image::get_paintable | ( | ) | 
Gets the image Gdk::Paintable being displayed by the Gtk::Image. 
The storage type of the image must be Gtk::Image::Type::EMPTY or Gtk::Image::Type::PAINTABLE (see get_storage_type()). The caller of this function does not own a reference to the returned paintable.
| Glib::RefPtr< const Gdk::Paintable > Gtk::Image::get_paintable | ( | ) | const | 
Gets the image Gdk::Paintable being displayed by the Gtk::Image. 
The storage type of the image must be Gtk::Image::Type::EMPTY or Gtk::Image::Type::PAINTABLE (see get_storage_type()). The caller of this function does not own a reference to the returned paintable.
| int Gtk::Image::get_pixel_size | ( | ) | const | 
Gets the pixel size used for named icons.
| Type Gtk::Image::get_storage_type | ( | ) | const | 
Gets the type of representation being used by the Gtk::Image to store image data. 
If the Gtk::Image has no image data, the return value will be Gtk::Image::Type::EMPTY.
| 
 | static | 
Get the GType for this class, for use with the underlying GObject type system.
| 
 | inline | 
Provides access to the underlying C GObject.

Default value: false
| void Gtk::Image::set | ( | const Glib::RefPtr< const Gio::Icon > & | icon | ) | 
| void Gtk::Image::set | ( | const Glib::RefPtr< Gdk::Paintable > & | paintable | ) | 
Sets a Gtk::Image to show a Gdk::Paintable. 
See new_from_paintable() for details.
| paintable | A Gdk::Paintable. | 
| void Gtk::Image::set | ( | const Glib::RefPtr< Gdk::Pixbuf > & | pixbuf | ) | 
See the Image::Image(const Glib::RefPtr<Gdk::Pixbuf>& pixbuf) constructor for details.
| pixbuf | A Gdk::Pixbuf. | 
| void Gtk::Image::set | ( | const std::string & | filename | ) | 
See the Image::Image(const std::string& file) constructor for details.
| filename | A filename. | 
| void Gtk::Image::set_from_icon_name | ( | const Glib::ustring & | icon_name | ) | 
Causes the Image to display an icon from the current icon theme.
If the icon name isn't known, a "broken image" icon will be displayed instead. If the current icon theme is changed, the icon will be updated appropriately.
| icon_name | An icon name. | 
| void Gtk::Image::set_from_resource | ( | const std::string & | resource_path | ) |

| void Gtk::Image::set_icon_size | ( | IconSize | icon_size | ) | 
Suggests an icon size to the theme for named icons.
| icon_size | The new icon size. | 
| void Gtk::Image::set_pixel_size | ( | int | pixel_size | ) | 
Sets the pixel size to use for named icons.
If the pixel size is set to a value != -1, it is used instead of the icon size set by set_from_icon_name().
| pixel_size | The new pixel size. | 
| 
 | 
A Glib::wrap() method for this object.
| 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. |
