程序中数据导出是经常有的需求，今天学习把文本导出到pdf文件。主要是用QPrinter，QPainter
- TextEditToPdf::TextEditToPdf(QWidget *parent, Qt::WFlags flags)
- : QDialog(parent, flags)
- {
- ui.setupUi(this);
- int ret = connect(ui.m_pExportBtn,SIGNAL(clicked()),this,SLOT(exportSlot()));
- }
- TextEditToPdf::~TextEditToPdf()
- {
- }
- void TextEditToPdf::exportSlot()
- {
- QTextDocument textDocument;
- QPrinter printer(QPrinter::ScreenResolution);
- printer.setPaperSize(QPrinter::A4);
- printer.setPageMargins(30,30,30,30,QPrinter::DevicePixel);
- printer.setOutputFormat(QPrinter::PdfFormat);
- printer.setOutputFileName(QString("11") + ".pdf");
- QPainter painter( &printer );
- QFont font;
- font.setPixelSize(15);
- painter.setFont(font);
- QTextOption textOption( Qt::AlignCenter);
- QPen pen;
- pen.setColor(Qt::black);
- pen.setWidth(1);
- painter.setPen(pen);
- int paperWidth = printer.width();
- int paperHeigth = printer.height();
- painter.drawText( QRect(QPoint( 30,30),QPoint(paperWidth - 30,paperHeigth- 20)),ui.m_pTextEdit->toPlainText (),textOption);
- textDocument.print(&printer);
- }
