SetPage on wx.html2.WebView doesn't work after building exe with PyInstaller or Nuitka

[bertbarabas]

Operating system: Windows 11 wxPython version & source: 4.2.0 Python version & source: 3.10.6

Description of the problem: When using wx.html2.WebView, SetPage works when running Python interactively but after building an exe either with PyInstaller or Nuitka, the widget remains blank or sometimes partially rendered.

This is true for both WEBVIEW_BACKEND_EDGE and WEBVIEW_BACKEND_IE. However when using WEBVIEW_BACKEND_IE the default allows a pop-up in the widget that has a "refresh" item. Clicking "refresh" will cause the page to render properly.

This used to work with wxPython 4.1.1.

Suggested work-arounds welcome!

As a workaround, you can modify your PyInstaller .spec file to include WebView2Loader.dll.

Thanks! This was exactly the information I needed.

I used a slight variation. Instead of updating the spec since I was using the autogenerated spec file, I used the --add-binary command line option instead. Specifically:

--add-binary ".venv\Lib\site-packages\wx\WebView2Loader.dll;."

Thanks very much.
