Structural events, for structural changes in the figures hierarchy, and for movement or resizing of the figure.
Figures can be transparent or opaque, and can be ordered into layers, thus allowing parts of a diagram to be hidden or excluded from certain operations. The basic function of these classes is to contain the location of a Connection’s endpoints and to register listeners that will be notified if the end of a connection is moved.

These include various buttons, Checkbox, and the text entry figure, Label. Operations to manage the figure’s place in the figure hierarchy, including adding and removing children and accessing them or its parent figure. For this, I’m using the GEF editor.
The Insets class draw2 used to represent the space within a figure that is allocated to the border.
The default update manager, DeferredUpdateManager, allows updates to be performed asynchronously by queuing work on the Display’s user interface thread. Each figure gets a graphical context, an instance of the Graphics class, that is passed as argument to the figure’s paint method.
Phone registration failures over specific period Tracking transaction payment processing platform Tracking a renewal or new signup transaction E-Commerce: Understand the connections in your data. The graphics objects in the lightweight system, known as figures in Draw2D, are treated as if they are normal windows.
FlowLayout — Lays out its children into either rows or columns, which is configurable either by using the constructor:. Draw2D is hosted in a SWT canvas heavyweight control and manages the painting and mouse events that occur in the host canvas by delegating them to Draw2D figures.
