Wrapping printing pages ...

[Jean Paul Martin]

Hi guys,
I am currently making a program that will read in an HTML file and display the contents onto the screen. That worked great. I have an option for printing and it works. However, printing fails when the page is larger than the size of the paper, as in could anyone help me wrap my page so that it follows to the next page ... thanks a lot.

//some variables i'm using are:
protected JTextPane m_editor;
protected PrintView m_printView;
  public void printData() {
getJMenuBar().repaint();
try {
    PrinterJob prnJob = PrinterJob.getPrinterJob();
    prnJob.setPrintable(this);
    if (!prnJob.printDialog())
return;
    setCursor( Cursor.getPredefinedCursor(
  Cursor.WAIT_CURSOR));
    prnJob.print();
    setCursor( Cursor.getPredefinedCursor(
  Cursor.DEFAULT_CURSOR));
    JOptionPane.showMessageDialog(this, 
  "Printing completed successfully", "Coroner's Printing ...",
  JOptionPane.INFORMATION_MESSAGE);
}
catch (PrinterException e) {
    e.printStackTrace();
    System.err.println("Printing error: "+e.toString());
}
    }//this part works great

    //problem is here, i'm not sure how to wrap up my page, otherwise, the printing works fine for just one page.
    public int print(Graphics pg, PageFormat pageFormat,
     int pageIndex) throws PrinterException {
pg.translate((int)pageFormat.getImageableX()-36, (int)  pageFormat.getImageableY()-36);
int wPage = (int)pageFormat.getImageableWidth();
int hPage = (int)pageFormat.getImageableHeight();
pg.setClip(0, 0, wPage,hPage);

// Only do this once per print
if (m_printView == null) {
    BasicTextUI btui = (BasicTextUI)m_editor.getUI();
    View root = btui.getRootView(m_editor);
    m_printView = new PrintView(m_doc.getDefaultRootElement(), 
root, wPage, hPage);
}
boolean bContinue = m_printView.paintPage(pg,hPage, pageIndex);
System.gc();

if (bContinue)
    return PAGE_EXISTS;
else {
    m_printView = null;
    return NO_SUCH_PAGE;
}

    }

//the inner class PrintView
class PrintView extends BoxView
{
    protected int m_firstOnPage = 0;
    protected int m_lastOnPage = 0;
    protected int m_pageIndex = 0;
    public PrintView(Element elem, View root, int w, int h) {
super(elem, Y_AXIS);
setParent(root);
setSize(w, h);
layout(w, h);
    }
    
    public boolean paintPage(Graphics g, int hPage, 
     int pageIndex) {
if (pageIndex > m_pageIndex) {
    m_firstOnPage = m_lastOnPage + 1;
    if (m_firstOnPage >= getViewCount())
return false;
    m_pageIndex = pageIndex;
}
int yMin = getOffset(Y_AXIS, m_firstOnPage);
int yMax = yMin + hPage;
Rectangle rc = new Rectangle();

for (int k = m_firstOnPage; k < getViewCount(); k++) {
    rc.x = getOffset(X_AXIS, k);
    rc.y = getOffset(Y_AXIS, k);
    rc.width = getSpan(X_AXIS, k);
    rc.height = getSpan(Y_AXIS, k);
    if (rc.y+rc.height > yMax)
break;
    m_lastOnPage = k;
    rc.y -= yMin;
    paintChild(g, rc, k);
}
return true;
    }
}

How does this have anything to do with J2ME? Will move to Swing.
