Trouble to print with QPrintPreviewWidget

[estanisgeyer]

Hi friends,

I'm trying to print some pages from a QPrintPreviewWidget, to call QPrintDialog to set the range of pages want to print, is printed every page, not the range. What I'm doing wrong? Any suggestions?

Follow small code:

Report.h

class Report: public QMainWindow
{
Q_OBJECT
public:
    Report(QWidget *parent = 0, QWidget *widgetReport = 0);
    QPrinter *printer;
    QPrintPreviewWidget *printPreview;
 
private:
    Ui::Report ui;
 
private slots:
    void print();
};
#endif

class Report: public QMainWindow
{
Q_OBJECT
public:
    Report(QWidget *parent = 0, QWidget *widgetReport = 0);
    QPrinter *printer;
    QPrintPreviewWidget *printPreview;

private:
    Ui::Report ui;

private slots:
    void print();
};
#endif

Report.cpp

#include "Report.h"
Report::Report(QWidget *parent, QWidget *widgetReport)
:QMainWindow(parent)
{
    ui.setupUi(this);
    setAttribute(Qt::WA_DeleteOnClose);
    this->showMaximized();
 
    printer = new QPrinter(QPrinter::HighResolution);
    printer->setOutputFormat(QPrinter::NativeFormat);
    printer->setOrientation(QPrinter::Portrait);
    printer->setPaperSize(QPrinter::A4);
    printer->setFullPage(true);
 
    printPreview = new QPrintPreviewWidget(printer, this);
    ui.gridLayout1->addWidget(printPreview);
 
    connect(ui.ActPrint, SIGNAL(triggered()), this, SLOT(print()));
    connect(printPreview, SIGNAL(paintRequested(QPrinter*)), widgetReport, SLOT(Print(QPrinter*)));
 
    printPreview->fitInView();
    printPreview->show();
}
 
void Report::print()
{
    QPrintDialog printDialog(printer, printPreview);
    printDialog.setMinMax(1, printPreview->numPages());
    if (printDialog.exec() == QDialog::Accepted)
    {
        qDebug() << printPreview->numPages(); // OK, its return 3 pages, but print all if range is one or two.
        printPreview->print();
    }
}

#include "Report.h"
Report::Report(QWidget *parent, QWidget *widgetReport)
:QMainWindow(parent)
{
    ui.setupUi(this);
    setAttribute(Qt::WA_DeleteOnClose);
    this->showMaximized();

    printer = new QPrinter(QPrinter::HighResolution);
    printer->setOutputFormat(QPrinter::NativeFormat);
    printer->setOrientation(QPrinter::Portrait);
    printer->setPaperSize(QPrinter::A4);
    printer->setFullPage(true);

    printPreview = new QPrintPreviewWidget(printer, this);
    ui.gridLayout1->addWidget(printPreview);
    
    connect(ui.ActPrint, SIGNAL(triggered()), this, SLOT(print()));
    connect(printPreview, SIGNAL(paintRequested(QPrinter*)), widgetReport, SLOT(Print(QPrinter*)));

    printPreview->fitInView();
    printPreview->show();
}

void Report::print()
{
    QPrintDialog printDialog(printer, printPreview);
    printDialog.setMinMax(1, printPreview->numPages());
    if (printDialog.exec() == QDialog::Accepted)
    {
        qDebug() << printPreview->numPages(); // OK, its return 3 pages, but print all if range is one or two.
        printPreview->print();
    }
}

It's possible to a bug? Or write my class in a way that these controls will not work? Someone has worked with QPrintPreviewWidget?

Hi guys, Anybody to help?

[seneca]

You widgetReport::Print method should read out the the print range and paint accordingly.

I've got the same problem here. I use pyqt.

Do you have solution already?

I've got a similar problem... Qt is too raw to use it in serious projects
I use .Net and I have never had any problems with printing (and print preview too) text and graphic. Printing is very important for my projects. I tried to convert one of my projects to Qt, but some things are impossible with Qt and some things are not documented as they should be.
