| virtual Glib::RefPtr< Object > | ref_accessibile_vfunc () | 
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::Pixbuf ("pixel buffer") from a file, and then display that.
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.
| Gtk::Image::Image | ( | const Glib::RefPtr< Gdk::Pixbuf >& | pixbuf | ) | 
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().
| void Gtk::Image::clear | ( | ) | 
Resets the image to be empty.
| Glib::RefPtr<Gio::Icon> Gtk::Image::get_gicon | ( | ) | 
Gets the Gio::Icon and size being displayed by the Gtk::Image.

nullptr. | Glib::RefPtr<const Gio::Icon> Gtk::Image::get_gicon | ( | ) | const | 
Gets the Gio::Icon and size 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.
nullptr. | 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.
nullptr. | IconSize Gtk::Image::get_icon_size | ( | ) | const | 
Gets the icon size used by the image when rendering icons.
| int Gtk::Image::get_pixel_size | ( | ) | const | 
Gets the pixel size used for named icons.
| Type Gtk::Image::get_storage_type | ( | ) | const |

If the Gtk::Image has no image data, the return value will be Gtk::Image::Type::EMPTY.
| Cairo::RefPtr<Cairo::Surface> Gtk::Image::get_surface | ( | ) | 
Gets the image #cairo_surface_t being displayed by the Gtk::Image.
The storage type of the image must be Gtk::Image::Type::EMPTY or Gtk::Image::Type::SURFACE (see get_storage_type()). The caller of this function does not own a reference to the returned surface.
nullptr if the image is empty. | Cairo::RefPtr<const Cairo::Surface> Gtk::Image::get_surface | ( | ) | const | 
Gets the image #cairo_surface_t being displayed by the Gtk::Image.
The storage type of the image must be Gtk::Image::Type::EMPTY or Gtk::Image::Type::SURFACE (see get_storage_type()). The caller of this function does not own a reference to the returned surface.
nullptr if the image is empty. | Glib::RefPtr<Gdk::Texture> Gtk::Image::get_texture | ( | ) | 
Gets the image Gdk::Texture being displayed by the Gtk::Image.
The storage type of the image must be Gtk::Image::Type::EMPTY or Gtk::Image::Type::TEXTURE (see get_storage_type()). The caller of this function does not own a reference to the returned texture.
nullptr if the image is empty. | Glib::RefPtr<const Gdk::Texture> Gtk::Image::get_texture | ( | ) | const | 
Gets the image Gdk::Texture being displayed by the Gtk::Image.
The storage type of the image must be Gtk::Image::Type::EMPTY or Gtk::Image::Type::TEXTURE (see get_storage_type()). The caller of this function does not own a reference to the returned texture.
nullptr if the image is empty. |
