Bokeh - Embedding in PyQt is not working

Hello

The question in short

Bokeh charts do not work properly when accessing web content through a QWebView. Loading and dragging is very slow, and the Tools do not work.

For a test, accessing anything in the Bokeh Gallery manifests this issue.

Any ideas if this can be fixed in the setups of the QWebView?

Detailed question

This question partially connects to this other question on google groups and this question on stack overflow.

I have a PyQt GUI with a QWebView that I use to browse the internet. If I navigate to any chart of the bokeh Gallery, the loading is extremely slow, and the bokeh Tools do not work.

Are there QWebSettings that one needs to set in order to fix this, as suggested in the post on SO?

(for context: my goal would be to use the bokeh server to host charts and widgets to be used through the QWebView, or at the very least to use bokeh to produce static content to show in the QWebView)

Thanks!

Hi pythonic,

Unfortunately I don’t know anyone who has any experience using Bokeh with Qt, so you may be exploring new territory. I will say that, as JS libraries go, Bokeh is fairly large, sophisticated, and demanding. Performance is certainly affected by the quality of level of development of the underlying browser engine and canvas implementation. I did find this SO post that may be relevant:

    [http://stackoverflow.com/questions/29055475/qwebview-or-qwebengineview](http://stackoverflow.com/questions/29055475/qwebview-or-qwebengineview)

It looks as though QWebView is being deprecated in favor of QWebEngineView, perhaps that might offer a better experience? Otherwise, I think you might have more luck getting detailed technical advice on QWebView on a Qt oriented list or forum.

If you do find a solution or workaround, please let us know, we can include it in the Bokeh docs.

Thanks,

Bryan
