Qt 4.4.0 Problem with QPrintPreviewDialog

[ad5xj]

I am having a problem with the new QPrintPreviewDialog. The widget will display but the document I am printing will not. The display area is only gray.

Environment: XP Home SP2 MinGW and Qt 4.4.0 coding in eclipse

Here is some code snippets. Please help:

QPrinter *printer = new QPrinter;
printer->setOutputFormat(QPrinter::NativeFormat);
printer->setPaperSize(QPrinter::Letter);
printer->setOrientation(QPrinter::Landscape);
 
QPrintPreviewDialog *dlg = new QPrintPreviewDialog(printer, this);
connect(dlg, SIGNAL(paintRequested(devPrint)), this, SLOT(slotPrintLog(devPrint)));
dlg->setWindowModality(Qt::ApplicationModal);
dlg->setModal(true);
dlg->setWindowTitle(QString("Session Log Report Preview"));
textEdit->document()->print(printer);
dlg->exec();

QPrinter *printer = new QPrinter;
printer->setOutputFormat(QPrinter::NativeFormat);
printer->setPaperSize(QPrinter::Letter);
printer->setOrientation(QPrinter::Landscape);

QPrintPreviewDialog *dlg = new QPrintPreviewDialog(printer, this);
connect(dlg, SIGNAL(paintRequested(devPrint)), this, SLOT(slotPrintLog(devPrint)));
dlg->setWindowModality(Qt::ApplicationModal);
dlg->setModal(true);
dlg->setWindowTitle(QString("Session Log Report Preview"));
textEdit->document()->print(printer);
dlg->exec();

To copy to clipboard, switch view to plain text mode 

===== code from slotPrintLog()=====

formatReport();
textEdit->print(devPrint);

formatReport();
textEdit->print(devPrint);

To copy to clipboard, switch view to plain text mode 

========== code from formatReport()=======

// Create the first document cursor
QTextCursor cursor(textEdit->document());
         . . . code to print report. . . .
                      .
                      .
                      .
cursor.format. . . and cursor.insertText . . .  etc.
textEdit->documentEnd();

cursor.format. . . and cursor.insertText . . .  etc.
textEdit->documentEnd();

Any ideas?

There is precious little documentation on this new widget and the dialog. The examples are minimal at best. I need some new ideas.

this connect won't work

connect( dlg, SIGNAL( paintRequested( devPrint ) ), this, SLOT( slotPrintLog( devPrint ) ) );

connect( dlg, SIGNAL( paintRequested( devPrint ) ), this, SLOT( slotPrintLog( devPrint ) ) );

To copy to clipboard, switch view to plain text mode 

you put value to signal and slot functions
