Draw2d is a layout and rendering toolkit building on top of SWT. Draw2d is a lightweight toolkit for displaying graphical components on an SWT Canvas. Lightweight means that all graphical components, which are called figures in Draw2d, are simply java objects, with no corresponding resource in the operating system. It hooks listeners for most SWT events, and forwards most of them to an EventDispatcher, which translates them into events on the appropriate figure. Paint events are forwarded from the figures to an UpdateManager, which coordinates painting and layouting on the canvas. Figures can be composed via a parent-child relationship. Every figure has a rectangular bounds inside which it, and its children, paint.
