Class BoxView

java.lang.Object
  javax.swing.text.View
      com.inet.html.views.BoxView

All Implemented Interfaces:

javax.swing.SwingConstants

Direct Known Subclasses:

BlockView, ContentView, ControlView, HRuleView, ImageView, InlineView, TableView

public abstract class BoxView
extends javax.swing.text.View

This class is the basic box used to represent and render all html elements. Any other type within the JWebEngine renderer have to extend this class. What this class does: - cache all relevant attributes for the underlying element - store the size and appearance of this box(borders, padding, font size, text align) by using BoxPainters - paint the box itself What this class does NOT: - have a layout(because not any box implementation requires a layout) - display content, this has to be done by the extensions
