I have tried adding the pdf.js viewer files in my project and it works in browsers like Chrome, Mozilla, Safari, etc, but it's not loading some pages in node-webkit and PyQt webkit.
I am trying to load the file using an iframe, like this:
<iframe src="/test/?file=/assets/pdf/example.pdf#page=3"> </iframe>
I've found this thread over at the Qt Forums, where thebeast44 posted a snippet of Qt code answering your question. My translation to python is below.
You'll also need to unpack the res folder from the author's original code, I think he just modified the viewer... I've also attached said code here.
from PyQt4 import QtCore
from PyQt4 import QtGui
from PyQt4 import QtNetwork
from PyQt4 import QtWebKit
class 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_())
