public class DefaultView
extends ViewPanel
implements WindowListener, ComponentListener

Base for constructing views.

This base view is an abstract class that provides mechanism that are necessary in any view :

• the painting and repainting mechanism.
• the optional frame handling.
• the frame closing protocol.

This view also handle a current selection of nodes and sprites.

The painting mechanism

The main method to implement is render(Graphics2D). This method is called each time the graph needs to be rendered anew in the canvas.

The render(Graphics2D) is called only when a repainting is really needed.

All the painting, by default, is deferred to a GraphRenderer instance. This mechanism allows developers that do not want to mess with the viewer/view mechanisms to render a graph in any Swing surface.

The optional frame handling

This abstract view is able to create a frame that is added around this panel (each view is a JPanel instance). The frame can be removed at any time.

The frame closing protocol

This abstract view handles the closing protocol. This means that it will close the view if needed, or only hide it to allow reopening it later. Furthermore it adds the "ui.viewClosed" attribute to the graph when the view is closed or hidden, and removes it when the view is shown. The value of this graph attribute is the identifier of the view.
