How can i print all the content of groupbox in any available printers?

ioanna

This is an image of the missing part which i wish to include in the printing.

this is my output which shows it was cut

this is the the code:

    QPrinter printer;
    QPainter painter;
    Dialog w;


    QPrintDialog printDialog(&printer);
    if (printDialog.exec() == QDialog::Accepted) {
        painter.begin(&printer);
                    printer.setPaperSize(QPrinter::A4);
                    printer.setPageMargins(2, 2, 2, 10, QPrinter::Millimeter);
                    printer.setFullPage(true);
                    double xscale = printer.pageRect().width() / double(w.width());
                    double yscale = printer.pageRect().height() / double(w.height());
                    double scale = qMin(xscale, yscale);
                    painter.translate(printer.paperRect().center());
                    painter.scale(scale, scale);
                    painter.translate(-w.width()/ 2, -w.height()/ 2);
        ui->groupBox->render(&painter);
      }

@ioanna Just use QPrinter returned by https://doc.qt.io/qt-5/qprintdialog.html#printer

ioanna

SIr i am a newbie, can you guide me how to use your suggested solution?

jsulm

@ioanna There is really nothing special:

if (printDialog.exec() == QDialog::Accepted) {
    QPrinter *printer = printDialog.printer();
    painter.begin(printer);

ioanna

It's the same the output is still like this.

@ioanna Then I guess your scaling is wrong.

ioanna

@jsulm sir i have the same result, i forgot to tell you that during run time the ui was also cut exactly the same with the one being printed. I can't find a way to display what i have designed in my UI form since it is too long with a height of 1.3k.

jsulm

@ioanna It looks like you did not put all your widgets in a layout. Do this first. https://doc.qt.io/qt-5/layout.html

ioanna

@jsulm is it possible to zoom out to view all my design?

jsulm

@ioanna Why don't you put your widgets into a layout instead?
You can't "zoom out" if part of your UI is not fitting into the window.

ioanna

@jsulm sir thanks. But i have a last question, can i stretch widgets to fit in A4 size?

jsulm

@ioanna If your UI is showing correctly (using layouts) then you will need to scale it when printing, so it fits A4.
