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.
Gtk::Image is a subclass of Gtk::Misc, which implies that you can align it (center, left, right) and add padding to it, using Gtk::Misc methods.
Gtk::Image is a "no window" widget (has no Gdk::Window of its own), so by default does not receive events. If you want to receive events on the image, such as button clicks, place the image inside a Gtk::EventBox, then connect to the event signals on the event box.
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 the file contains an animation, the image will contain an animation.
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. (Or for animations, use Gdk::PixbufAnimation::create_from_file()).
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().
| Gtk::Image::Image | ( | const Gtk::StockID & | stock_id, | 
| IconSize | size | ||
| ) | 
Creates an Image displaying a stock icon.
Sample stock icon identifiers are Gtk::Stock::OPEN, Gtk::Stock::EXIT. Sample stock sizes are Gtk::ICON_SIZE_MENU, Gtk::ICON_SIZE_SMALL_TOOLBAR. If the stock icon name isn't known, a "broken image" icon will be displayed instead. You can register your own stock icon names - see Gtk::IconFactory::add().
