import java.awt.print.*;
class SketchView extends JComponent
implements Observer,
ActionListener,
Printable,
Pageable{
//Always two pages
public int getNumberOfPages()
{return 2;}
//Return the printable object that will render the page
public Printable getPrintable(int pageIndex)
{
if (pageIndex == 0)
return new SketchCoverPage(theApp);
else
return this;
}
public PageFormat getPageFormat(int pageIndex)
{
//get the default page format and its Paperobject.
PageFormat pageFormat = PrinterJob.getPrinterJob().defaultPage();
Paper paper = pageFormat.getPaper();
if(pageIndex == 0)//if its the cover page..
{//..make the margins twiece the size
double leftMargin = paper.getImagebleX()-paper.getImagebleWidth()-leftMargin;
double bottomMargin = paper.getImagebleY()-paper.getHeight()-paper.getImagebleHeight()-topMargin;
//Double the margins sizes
leftMargin *= 2;
rightMargin *= 2;
topMargin *= 2;
bottomMargin *= 2;
paper.setImageableArea(leftMargin, topMargin, //Set new printable area
paper.getWidth()-leftMargin-rightMargin,
paper.getHeight()-topMargin-bottomMargin);
paperFormat.setPaper(paper);//Restore the paper
}
else
{ //We are printing a skecth so decide on portrait ot landscape
Rectangle rect = getModelExtent();
//If the width is more than the height, set landscape
if(rect.width > rect.height)
pageFormat.setOrientation(pageFormat.LANDSCAPE);
}
return pageFormat;
}
public int print(Graphics g,PageFormat pageFormat, int pageIndex)throws PrinterException
{
if(pageIndex != 1)
return NO_SUCH_PAGE;
Graphics2D g2D = (Graphics2D)g;
Rectangle rect = getModelExtent();
//Calculate the scale to fit sketch to page
double scaleX = pageFormat.getImagebleWidth() /rect.width;
double scaleY = pageFormat.getImagebleHeight() /rect.height;
double scale = Math.min(scaleX,scaleY); //getminimum scale factor
//Move origin to page printing area corner
g2D.translate(pageFormat.getImagebleX(), pageFormat.getImagebleY());
g2D.scale(scale,scale);
g2D.translate(-rect.x, -rect.y);
print(g2D);
return PAGE_EXISTS;
}
if (name.equals(printAction.getValue(NAME)))
{
PrinterJob = PrinterJob.getPrinterJob();//get a printing object
printJob.setPageble(theApp.getView());//the view is the page source
if (printJob.printDialog());//display print dialog
{//if true is returned
try
{
printJob.print();
}
catch(PrinterException pe)
{
System.out.println(pe);
JOptionPane.showMessageDialog(SketchFrame.this,
"Error printing a sketch.",
"Printer Error",
JOptionPane.ERROR_MESSAGE);
}
}
}
}
Thanks!
