com.lightdev.app.shtm.SHTMLBlockView
public class SHTMLBlockView
HTML block view copied from javax.swing.text.html.BlockView.java The original class is only changed in the way that it now uses a com.lightdev.app.shtm.SHTMLBoxPainter instead of javax.swing.text.html.StyleSheet.BoxPainter Admittedly ugly solution which hopefully can be corrected once Sun decided to tidy up the CSS part of Swing.

public void setParent(javax.swing.text.View parent)
This is implemented
to forward to the superclass as well as call the
setPropertiesFromAttributes()
method to set the paragraph properties from the css
attributes. The call is made at this time to ensure
the ability to resolve upward through the parents
view attributes.
