QWebView for running D3 javascript is slow after reloading HTML.

[Konstantin Tokarev]

Which version of QtWebKit are you using?
Does problem reproduce if you remove cache settings?

@Konstantin-Tokarev

I am using Qt 5.5

I am unsure how to remove the cache settings but I will try that right now.

Edit: It appears that

webSetting->setObjectCacheCapacities(0, 0, 0);

should disable cache, so I have tried this.

[Konstantin Tokarev]

Yep, try without this line

@Konstantin-Tokarev

I have tried it with all combinations of the following settings (one, other one, both, none)

webSetting->setObjectCacheCapacities(0, 0, 0);
webSetting->setMaximumPagesInCache(1);

I am going to try another Qt version and see if that has an effect.

You should use qtwebkit from 5.212 branch, version coming with Qt 5.5 is obsolete

@Konstantin-Tokarev said in QWebView for running D3 javascript is slow after reloading HTML.:

5.212

Thanks for the advice. Is 5.212 > 5.10?

And why such a weird version number? Should I download form git or is the qt installer going to have it?

[Konstantin Tokarev]

@CLang For use with Qt 5.10, get binaries from http://download.qt.io/snapshots/ci/qtwebkit/5.212/latest/qtwebkit/

And why such a weird version number?

It isn't tied to particular Qt version, instead respective WebKitGTK's branch name is used as a basis

@Konstantin-Tokarev

Thanks for all your help.

Does this mean I could download the source, compile it with cmake and msvc2013_64 and use it with qt5.5?

[Konstantin Tokarev]

No, MSVC 2013 is not supported. You need MSVC >= 2015 or MinGW >= 4.9

@Konstantin-Tokarev I actually downgraded to 5.3 and the issue has resolved.

What's the best way to resolve this post? Reply to the initial post with the solution and change to 'solved'?

The issue seems to be in Qt5.5 - I compiled with 5.3 and the issue is gone.
