我正在使用pyqt5 我曾经 QText文档 并试图打印文本,但我在左侧获得边距。我尽了一切努力来消除差距,但它仍然没有消失。我曾经 设置页边距 和 setDocumentMargin 但仍然在左侧获得优势。

以下是代码:

from PyQt5.QtWidgets import QApplication, QMainWindow, QTextEdit, QVBoxLayout, QPushButton, QWidget
from PyQt5.QtGui import QTextDocument, QTextCursor, QTextCharFormat,QTextFrameFormat,QTextBlockFormat
from PyQt5.QtPrintSupport import QPrinter, QPrintDialog,QPrintPreviewDialog
from PyQt5 import QtCore,QtWidgets,QtGui
import sys

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        self.initUI()

    def initUI(self):
        self.setGeometry(100, 100, 800, 600)
        self.setWindowTitle('QTextDocument Example')

        central_widget = QWidget()
        layout = QVBoxLayout()

        self.text_edit = QTextEdit()
        layout.addWidget(self.text_edit)

        self.generate_button = QPushButton('Generate Document')
        self.generate_button.clicked.connect(self.generateDocument)
        layout.addWidget(self.generate_button)

        central_widget.setLayout(layout)
        self.setCentralWidget(central_widget)

    def generateDocument(self):
        # Clear any previous content
        self.text_edit.clear()

        # Create a QTextDocument instance
        doc = QTextDocument()
        cursor = QTextCursor(doc)
        content = "HI there"
        cursor.insertText(content)
        printer = QPrinter()
        printer.setFullPage(True)
        printer.setPageMargins(0.1,0.1,0.1,0.1,QPrinter.Millimeter)
        printer.setPaperSize(QPrinter.PageSize.Letter)
        printer.setOrientation(QPrinter.Orientation.Portrait)
        doc.setDocumentMargin(0)
        self.text_edit.setDocument(doc)
        doc.print_(printer)


if __name__ == '__main__':
    app = QApplication(sys.argv)
    mainWindow = MainWindow()
    mainWindow.show()
    sys.exit(app.exec_())

这是其中一个输出的图片内容有很多边缘在左侧。
