| <p>Draw2d is a layout and rendering toolkit building on top of SWT. It may be used standalone (outside of Eclipse) or in combination with the GEF or Zest component.</p> |

| |
| <h3>Overview</h3> |
| <p>Draw2d is a lightweight toolkit for displaying graphical components on an SWT Canvas. Lightweight means that all |
| graphical components, which are called <i>figures</i> in Draw2d, are simply java objects, with no corresponding resource |
| in the operating system. |
| </p><p> |
| A LightweightSystem associates a figure composition with an SWT Canvas. 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. |
| </p><p> |
| Figures can be composed via a parent-child relationship. Every figure has a rectangular bounds inside which it, |
| and its children, paint. A layout manager can be used to place children based on their index and/or constraint. |
| Figures can be updated in ways which affect their appearance or size, and the update manager ensures that only one |
| layout occurs, followed by a repaint of only the region which was updated. |
| </p><p> |
| Any type of diagram, document, or drawing can be easily constructed and efficiently updated by combining the provided |
| figure and layout implementations along with the use of custom figures or layouts when needed. |
| </p> |
