我正在尝试将 QWidget ui 输出到这样的 pdf 文件;

const QString filename = "class1bills.pdf";

printer = new QPrinter(QPrinter::HighResolution);
printer->setOutputFormat(QPrinter::PdfFormat);
printer->setOrientation(QPrinter::Portrait);
printer->setPaperSize(QPrinter::A4);
printer->setPageSize(QPrinter::A4);
printer->setPageMargins (15,15,15,15,QPrinter::Millimeter);
printer->setFullPage(false);
printer->setOutputFileName(filename);

painter = new QPainter(printer);

class1Bill->render(painter, QPoint(), QRegion(), QWidget::DrawChildren | QWidget::DrawWindowBackground);

painter->begin(printer);
painter->end();

assert(QFile::exists(filename)); 

class1Bill是继承QWidget的类的对象。一切正常,但是当我打开 pdf 文件时,我希望小部件 ui 看起来适合 A4 页面大小,但它看起来非常小,我什至乍一看都没有看到它。如何使小部件 ui 适合我设置的 A4 纸张尺寸?

设置printer->setFullPage(true);以适合纸张尺寸
