Class DrawingArea

public class DrawingArea extends Widget

Deprecated: This class is part of the java-gnome 2.x family of libraries, which, due to their inefficiency and complexity, are no longer being maintained and have been abandoned by the java-gnome project. This class may in the future have an equivalent in java-gnome 4.0, try looking for org.gnome.gtk.DrawingArea. You should be aware that there is a considerably different API in the new library: the architecture is completely different and most notably internals are no longer exposed to public view.

The DrawingArea widget is used for creating custom user interface elements. It's essentially a blank widget you can draw on. Use getWindow to get the [Gdk] Window to draw on.

General practice is to use a ExposeListener and then implement its exposeEvent(ExposeEvent) method and do your drawing when ExposeEvent is fired.

The upstream API documentation also suggests that for some use cases it may be easier to create a [Gtk] Image and then call it's getPixbuf() method to get at the underlying [Gdk] Pixbuf which you can make changes to and then referesh from.

Deprecated: Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
