我在Qt论坛上找到了这个话题，thebeast44发布了一段Qt代码来回答您的问题。我对python的翻译如下。
您还需要从作者的原始代码中解压缩res文件夹，我认为他只是修改了查看器…我还在此处附加了代码。
from PyQt4 import QtCorefrom PyQt4 import QtGuifrom PyQt4 import QtNetworkfrom PyQt4 import QtWebKitclass PDFViewer(QtWebKit.QWebView): pdf_viewer_page = 'res/pdf-viewer.html' def __init__(self, parent=None): super().__init__(parent) self.settings = QtWebKit.QWebSettings.globalSettings() self.settings.setAttribute(QtWebKit.QWebSettings.LocalContentCanAccessFileUrls, True ) self.settings.setAttribute(QtWebKit.QWebSettings.LocalContentCanAccessRemoteUrls, True ) self.settings.setAttribute(QtWebKit.QWebSettings.DeveloperExtrasEnabled, True ) nam = QtNetwork.QNetworkAccessManager() page = QtWebKit.QWebPage(self) page.setNetworkAccessManager(nam) self.setPage(page) self.loadFinished.connect(self.onLoadFinish) self.setUrl(QtCore.QUrl(self.pdf_viewer_page)) def onLoadFinish(self, success): if success: self.page().mainframe().evaluateJavascript("init();")if __name__ == '__main__': import sys app = QtGui.QApplication(sys.argv) viewer = PDFViewer(parent=None) viewer.show() sys.exit(app.exec_())
