問題描述

我的發(fā)票

我在 Python 中有一個幾乎完成的項目，它使用 QPrintPreviwDialog 根據(jù)上圖顯示和打印數(shù)據(jù).我使用 QTextDocumento 來處理 HTML.

有沒有辦法在頁碼空間中寫一些東西.我想將黃色信息寫入頁碼空間作為頁腳.或者是否有其他解決方案來顯示頁腳而不是使用不屬于 python 的 pyjasper?

My Invoice

I have a almost finishd project in Python which uses QPrintPreviwDialog to show and print data according to the picture above. I have used QTextDocumento to handle the HTML.

Is there a way to write something in page number space. I would like to write the info in yellow to the page number space to serve as footer. Or is there other solution to show footer instead of using pyjasper, one that are not part of python?

Translating my previous answer from C++ to python and modifying the position of the text I show how to add a footer.

from PyQt5 import QtCore, QtGui, QtWidgets, QtPrintSupport

textMargins = 12
borderMargins = 10

def mmToPixels(printer, mm):
    return mm * 0.039370147 * printer.resolution()

def paintPage(pageNumber, pageCount, painter, doc, textRect, footerHeight):
    painter.save()
    textPageRect = QtCore.QRectF(QtCore.QPointF(0, pageNumber*doc.pageSize().height()), doc.pageSize())
    painter.setClipRect(textRect)
    painter.translate(0, -textPageRect.top())
    painter.translate(textRect.left(), textRect.top())
    doc.drawContents(painter)
    painter.restore()
    footerRect = QtCore.QRectF(textRect)
    footerRect.setTop(textRect.bottom())
    footerRect.setHeight(footerHeight)

    # draw footer
    painter.save()
    pen = painter.pen()
    pen.setColor(QtCore.Qt.blue)
    painter.setPen(pen)
    painter.drawText(footerRect, QtCore.Qt.AlignCenter, "Page {} of {}".format(pageNumber+1, pageCount))
    painter.restore()


def printDocument(printer, doc):
    painter = QtGui.QPainter(printer)
    doc.documentLayout().setPaintDevice(printer)
    doc.setPageSize(QtCore.QSizeF(printer.pageRect().size()))
    pageSize = printer.pageRect().size()
    tm = mmToPixels(printer, textMargins)
    footerHeight = painter.fontMetrics().height()
    textRect = QtCore.QRectF(tm, tm, pageSize.width() - 2 * tm, pageSize.height() - 2 * tm - footerHeight)
    doc.setPageSize(textRect.size())
    pageCount = doc.pageCount()

    for pageIndex in range(pageCount):
        if pageIndex != 0:
            printer.newPage()
        paintPage(pageIndex, pageCount, painter, doc, textRect, footerHeight)

if __name__ == '__main__':
    import sys

    app = QtWidgets.QApplication(sys.argv)
    document = QtGui.QTextDocument()
    cursor = QtGui.QTextCursor(document)
    blockFormat = QtGui.QTextBlockFormat()

    for i in range(10):
        cursor.insertBlock(blockFormat)
        cursor.insertHtml("<h1>This is the {} page</h1>".format(i+1))
        blockFormat.setPageBreakPolicy(QtGui.QTextFormat.PageBreak_AlwaysBefore)

    printer = QtPrintSupport.QPrinter(QtPrintSupport.QPrinter.HighResolution)
    printer.setPageSize(QtPrintSupport.QPrinter.A4)
    printer.setOutputFormat(QtPrintSupport.QPrinter.PdfFormat)

    dialog = QtPrintSupport.QPrintPreviewDialog(printer)
    dialog.paintRequested.connect(lambda print, doc=document: printDocument(printer, doc))


    dialog.exec_()
