QPrinter output in portrait instead landscape in windows

[jiveaxe]

Hi,
I have the following code for printing to pdf a widget:

void MainWindow::magToPdf()
{
	if(magazineViewer) {
		QPrinter printer;
		printer.setOrientation(QPrinter::Landscape);
		printer.setOutputFileName(magazineViewer->windowTitle() + ".pdf");
		printer.setOutputFormat(QPrinter::PdfFormat);
		QPixmap qpm = QPixmap::grabWidget(magazineViewer);
		if(qpm.isNull()) {
			QMessageBox::critical(0, "Error", "Can not capture the window", QMessageBox::Cancel);
			return;
		}
		QPainter p;
		p.begin(&printer);
		p.drawPixmap(85, 32, qpm);
		p.end();
	}
}

void MainWindow::magToPdf()
{
	if(magazineViewer) {
		QPrinter printer;
		printer.setOrientation(QPrinter::Landscape);
		printer.setOutputFileName(magazineViewer->windowTitle() + ".pdf");
		printer.setOutputFormat(QPrinter::PdfFormat);
		QPixmap qpm = QPixmap::grabWidget(magazineViewer);
		if(qpm.isNull()) {
			QMessageBox::critical(0, "Error", "Can not capture the window", QMessageBox::Cancel);
			return;
		}
		QPainter p;
		p.begin(&printer);
		p.drawPixmap(85, 32, qpm);
		p.end();
	}
}

To copy to clipboard, switch view to plain text mode 

In linux it works fine: the printed page is in landscape orientation but in windows acrobat shows it in portrait, cutting the right side of the captured widget.

Is it possible to resolve this behaviour?

Thanks

Could you attach a minimal compilable test application? As far as I remember, it worked just fine for me on Windows when I last happened to try.

Here a small code with the same problem; press F8 to print.

#include <QApplication>
#include <QDialog>
#include <QtGui>
 
class Dialog: public QDialog
{
	Q_OBJECT
 
	public:
		Dialog(QWidget *parent=0);
 
	private:
		QLabel *label;
		void keyPressEvent(QKeyEvent *event);
		void magToPdf();
 
};
 
Dialog::Dialog(QWidget *parent)
	:QDialog(parent)
{
    label = new QLabel("QT Rules!");
	label->setStyleSheet("font-size: 80px");
 
	QHBoxLayout *horizontal = new QHBoxLayout;
    horizontal->addStretch();
    horizontal->addWidget(label);
    horizontal->addStretch();
 
	QVBoxLayout *vertical = new QVBoxLayout;
	vertical->addStretch();
	vertical->addLayout(horizontal);
	vertical->addStretch();
 
    setLayout(vertical);
 
	setWindowTitle("Simple QPrint");
	setFixedSize(900,667);
}
 
void Dialog::keyPressEvent(QKeyEvent *event)
{
	if(event->key() == Qt::Key_F8)
		magToPdf();
}
 
void Dialog::magToPdf()
{
     QPrinter printer;
     printer.setOrientation(QPrinter::Landscape);
     printer.setOutputFileName(windowTitle() + ".pdf");
     printer.setOutputFormat(QPrinter::PdfFormat);
     QPixmap qpm = QPixmap::grabWidget(this);

Attached PDF was generated with Qt/Win 4.3.2.

In windows I have QT 4.3.1 . Upgrading should solve the problem?

Sorry, I don't have Qt 4.3.1 installed anymore so I cannot test the difference myself. But as I said, it works for me with Qt 4.3.2.
