Graphics2D in a DefaultStyleDocument
in [Java Programming]
|
From: Elliot on 19 Feb 2010 13:15 Hi I currently use a lot of code to parse and print a multi-page document with a lot of Graphics2D objects. I need to display the same document in a JTextPane. I would like to create a new class that could be used by either the repaginate() and print() routines for the print job or by a new paint() routine for the Swing components. I would like to add the Graphics2D objects to a DefaultStyledDocument and then add the styled document to a JTextPane. I think this would be the fastest way to draw everything. First, is it possible to add paint graphic 2d on a StyledDocument? Second, I do not want to duplicate any of the existing complex parsing code for the print job. I need to figure out how to create a new class containing this logic that could be used by either the current repaginate() and print() methods or new paint() method. Any ideas would be really welcome. Thanks Elliot

If a Graphics2D instance is associated with a Component you can use the insertComponent() method of JTextPane: <http://java.sun.com/javase/6/docs/api/javax/swing/JTextPane.html #insertComponent(java.awt.Component)> If it's a BufferedImage, you can wrap it in a JComponent and override the paintComponent() method to call drawImage(). -- John B.

I do that all the time for print preview only in reverse. -- Knute Johnson email s/nospam/knute2010/

Or use a JLabel with an ImageIcon, instead of writing custom paintComponent :-) -- Daniel Pitts' Tech Blog: <http://virtualinfinity.net/wordpress/>

Somewhere between the two approaches, I like to implement the Icon interface. As an example, here's a handy component for seeing the effect of various layout managers: /** * A label having an icon showing the icon's center. * @author John B. Matthews */ private static class SizeLabel extends JLabel implements Icon { private static final Font FONT = new Font("Serif", Font.PLAIN, 16); private static final int WIDE = 72; private static final int HIGH = 24; public SizeLabel() { this.setHorizontalAlignment(JLabel.CENTER); this.setVerticalAlignment(JLabel.CENTER); this.setHorizontalTextPosition(JLabel.CENTER); this.setVerticalTextPosition(JLabel.TOP); this.setIconTextGap(0); this.setFont(FONT); this.setPreferredSize( new Dimension(4 * WIDE / 3, 8 * HIGH / 3)); this.setMinimumSize(this.getPreferredSize()); this.setIcon(this); } public void paintIcon(Component c, Graphics g, int x, int y) { g.setColor(Color.darkGray); g.fillRect(x, y, WIDE, HIGH); int x2 = x + WIDE / 2; int y2 = y + HIGH / 2; String s = "(" + x2 + ", " + y2 + ")"; int w2 = g.getFontMetrics().stringWidth(s) / 2; int h2 = g.getFontMetrics().getDescent() + 1; g.setColor(Color.white); g.drawString(s, x2 - w2, y2 + h2); } public int getIconWidth() { return WIDE; } public int getIconHeight() { return HIGH; } } -- John B.
