PDF Page Cut Off

[asweetroxxi]

i created a pdf with QtextDocument. I have a table in the pdf but the bottom of the page cuts the text instead of printing on a new page(for example my table has 300 rows, page 1 shows 1-50,page 2 shows 100-50 and so on. is there anyway to prevent the overflow.
this is the standered pdf :

1.
//    QPrinter *printer=new QPrinter(QPrinter::HighResolution);
 
 2.
//    printer->setPaperSize(QPrinter::A4);
 
 3.
//    printer->setOutputFormat(QPrinter::PdfFormat);
 
 4.
//    printer->setOrientation(QPrinter::Portrait);
 
 5.
//    printer->setFullPage(true);
 
 6.
//    printer->setOutputFileName(fileName);
 
 
 
//and this is the table 
 
 
1.
    // Print Table
 
 2.
    QTableWidget *table=new QTableWidget();
 
 3.
    m_mainApp->m_table->SetTableWidget(table);
 
 4.
    table->setGeometry(0,0,printer.pageRect().width(),printer.pageRect().height());
 
 5.
    table->setAutoScroll(false);
 
 6.
    m_mainApp->m_table->InitTablePrint(index,printer.pageRect().width());
 
 7.
    int nbPage=m_mainApp->m_table->GetNbPrintPage(index,printer.pageRect().height());
 
 8.
    for(int page=0;page<nbPage;page++)
 
 9.
    {
 
 10.
        m_mainApp->m_table->currentIndex=-1;
 
 11.
        m_mainApp->m_table->InitTablePrint(index,printer.pageRect().width());
 
 12.
        m_mainApp->m_table->FillTablePrint(index,printer.pageRect().height(),page);
 
 13.
        painter.save();
 
 14.
        QTextDocument *editor=QTableWidget2QTextDocument(table);
 
 15.
        painter.scale(printer.resolution()/(screenResolution*1.5f), printer.resolution()/(screenResolution*1.5f));
 
 16.
        editor->drawContents(&painter);
 
 17.

you have to figure out how many rows to print on each page and draw 'separate' tables

[asweetroxxi]

1. how would i draw the seperators sorry im just starting so coding is weak.
2. what if i cant draw separate tables

[amleto]

use a table that will fit on a page and pass data to it

[asweetroxxi]

so i didnt set this code up it was given to me and the person who gave it to me isnt able to be around to help here is what i got so far.


this function prints and painter on a pdf, it prints a text document table and renders a graph

int index=ui->m_tableWidgetLogger->currentRow();
    if(index<0)
        return;
     QPrinter screenPrinter(QPrinter::ScreenResolution);
     int screenResolution = screenPrinter.resolution();
     QPrinter printer(QPrinter::HighResolution);
     printer.setOrientation(QPrinter::Portrait);
     printer.setPaperSize(QPrinter::A4);
     printer.setOutputFormat(QPrinter::PdfFormat);
     printer.setOutputFileName(fileName);
 
    QPainter painter;
    painter.begin(&printer);
 
    QPen pen(Qt::black, 2, Qt::SolidLine);
    painter.setPen(pen);
    painter.drawRoundRect(0,0,7400,1050,25,25);
//    QPen pen(Qt::black, 20, Qt::SolidLine);
//    painter.setPen(pen);
//    QLineF line(10,10,15000,10);

    painter.scale(0.75f,0.75f);

as a test i created a new project and and used setrowcount() and was able to figure that i needed 200 rows per page. i tried to test for how to create page breaks or split it but nothing seems to work. i was also joping to center that table which is also giving issues.

any help would be great and im sorry i am entry level so im not that quick and coding is not so amazing, iunderstand best by seeing to examples are a huge help
