Printing Help...

[chiragkini]

Hey guys,
U all know all in java JComponent can be printed. But i want to preview them before printing in Landscape Orientation. I have done lots of digging & googling..
But most of the solutions for the previewing only the Printable object such as JtextPane, JEditorpane, textfields, textarea....


I have one JPanel in which i have lots of labels whose values are loaded from the database . for eg: marksheet of student....
Now i wanted to Preview this JPanel in some Preview window with capability of zooming & changing page orientation etc..

SO please guys anyone who has faced such problem or know the solution help me out...
Its really urgent....

Thanks in Advance....

Anything that's Printable has to render onto a graphics context, which means you can render it onto an offscreen buffer as well, and then display that. The steps are, create a BufferedImage of the desired size, get it's graphics context, call 'print' on your top level Printable with that graphics context, then display your image in another component :

final BufferedImage preview = new BufferedImage(...size etc...);

Graphics graphics = preview.getGraphics();

{your Printable}.print(g, {a suitable page format}, pageNum);

JComponent customComp = new JComponent() {
  public void paintComponent(Graphics g) {
    g.drawImage();
  }
};

...add your compont to some content pane on some frame somwhere and see your preview...

...when all done, don't forget this!

graphics.dispose();
