Pratical example of QPrintPreviewDialog

[patrik08]

Hi all,

I'm needing of the pratical example of how use the class QPrintPreviewDialog. I did not find no documentation about this. I need a pratical example.
I think that the Throlltec's must update the samples programs.

this piece of code is from
http://fop-miniscribus.googlecode.co...o/textedit.cpp

its only a qt4.4.1/demos/textedit + OpenOffice odt reader

to get full svn code open:
http://www.qt-apps.org/content/show....?content=80650

void TextEdit::filePrintPreview()
{
#ifndef QT_NO_PRINTER
    QPrinter printer(QPrinter::HighResolution);
    QPrintPreviewDialog preview(&printer, this);
    preview.setWindowFlags ( Qt::Window );
    connect(&preview, SIGNAL(paintRequested(QPrinter *)), SLOT(printPreview(QPrinter *)));
    preview.exec();
#endif
}
 
void TextEdit::printPreview(QPrinter *printer)
{
#ifndef QT_NO_PRINTER
    textEdit->print(printer);
#endif
}

void TextEdit::filePrintPreview()
{
#ifndef QT_NO_PRINTER
    QPrinter printer(QPrinter::HighResolution);
    QPrintPreviewDialog preview(&printer, this);
    preview.setWindowFlags ( Qt::Window );
    connect(&preview, SIGNAL(paintRequested(QPrinter *)), SLOT(printPreview(QPrinter *)));
    preview.exec();
#endif
}

void TextEdit::printPreview(QPrinter *printer)
{
#ifndef QT_NO_PRINTER
    textEdit->print(printer);
#endif
}

IMO: if you like to build static QPrintPreviewDialog append his icon

Thanks to patrik08 by your help.

I think that the objective of this forum be help the persons and not depreciate the questions, by more samples that they be.

hi.
why the printer in this function:

void dlg_account::on_btn_print_clicked()
{    
      QPrinter printer(QPrinter::HighResolution);
      printer.setFullPage( true );
           QPrintPreviewDialog preview(&printer, this);
           preview.setWindowFlags ( Qt::Window );
           connect(&preview, SIGNAL(paintRequested(QPrinter* )), SLOT(print(QPrinter* )));
           preview.exec();
}

void dlg_account::on_btn_print_clicked()
{    
      QPrinter printer(QPrinter::HighResolution);
      printer.setFullPage( true );
           QPrintPreviewDialog preview(&printer, this);
           preview.setWindowFlags ( Qt::Window );
           connect(&preview, SIGNAL(paintRequested(QPrinter* )), SLOT(print(QPrinter* )));
           preview.exec();
}

isnt recognised in the:

void dlg_account::print( QPrinter* printer)
{
    QPainter *painter=new QPainter(printer);
    QRect paper = printer->pageRect();
    painter->setPen(Qt::black);
    painter->setFont(QFont("Sans",14,0,0));
    painter->drawText(QRect(0,0,100,100),Qt::AlignLeft||Qt::AlignTop,"page1");
}

void dlg_account::print( QPrinter* printer)
{
    QPainter *painter=new QPainter(printer);
    QRect paper = printer->pageRect();
    painter->setPen(Qt::black);
    painter->setFont(QFont("Sans",14,0,0));
    painter->drawText(QRect(0,0,100,100),Qt::AlignLeft||Qt::AlignTop,"page1");
}
