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.

Creates am 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().
