public class WrappedXMLView
extends WrappedPlainView

The XML View uses the XML scanner to determine the style (font, color) of the text that it renders.

Note: The XML Editor package is based on the JavaEditorKit example as described in the article 'Customizing a Text Editor' by Timothy Prinzing . See: http://java.sun.com/products/jfc/tsc/articles/text/editor_kit/

Method Detail

paint

public void paint(Graphics g,
                  Shape a)

Invalidates the scanner, to make sure a new range is set later.

Overrides:

paint in class WrappedPlainView

Parameters:

g - the graphics context.

a - the shape.

See Also:

drawUnselectedText

protected int drawUnselectedText(Graphics g,
                                 int x,
                                 int y,
