title: Embed wxPython's PDFViewer into PyQt5 App
body: <p>After having searched the internet, there seems to be no good (and free) solution for a PDF Viewer to include in a PyQt5 App.</p>
  
  <p>On the other hand in wxPython there is the pdfViewer, which works well.</p>
  
  <p>Is there a way to include the wxPython's pdfViewer into a PyQt5 App, so the PyQt5 App will show the wxPython pdfViewer in the main window?</p>
  
  <p>Or ... even better ... is there an usable PDF Viewer for PyQt5?</p>
  
  <p>Thanks!</p>
