问题描述
我尝试遵循以下答案:How to use PyQT5 to convert multiple HTML docs to PDF in one loop
我对其进行了修改,以转换在本地文件夹中找到的所有html文件。例如htmls是要转换的html文件的列表:[Q:\ Ray \ test1.html,Q:\ Ray \ prac2.html]
这是代码。但是,当我尝试运行它时,Python会冻结,我必须停止运行。
import os
import glob
from PyQt5 import QtWidgets,QtWebEngineWidgets
class PdfPage(QtWebEngineWidgets.QWebEnginePage):
def __init__(self):
super().__init__()
self._htmls = []
self._current_path = ""
self.setZoomFactor(1)
self.loadFinished.connect(self._handleLoadFinished)
self.pdfPrintingFinished.connect(self._handlePrintingFinished)
def convert(self,htmls):
self._htmls = iter(zip(htmls))
self._fetchNext()
def _fetchNext(self):
try:
self._current_path = next(self._htmls)
except StopIteration:
return False
def _handleLoadFinished(self,ok):
if ok:
self.printToPdf(self._current_path)
def _handlePrintingFinished(self,filePath,success):
print("finished:",success)
if not self._fetchNext():
QtWidgets.QApplication.quit()
if __name__ == "__main__":
current_dir = os.path.dirname(os.path.realpath(__file__))
folder= current_dir+ '\\*.HTML'
htmls= glob.glob(folder)
app = QtWidgets.QApplication([])
page = PdfPage()
page.convert(htmls)
app.exec_()
print("finished")
