Doesn't run on Qt 5.6 in Windows (missing QtWebKit)

QtWebKit was removed from Qt 5.6.

QtWebKit in Qt 5.6 can still be installed, it is just not included in standard Qt distribution anymore. E.g. in Arch Linux you can install qt5-webkit package.

I can switch to QtWebEngine, but QtWebEngine is much more resource intensive (it eats a lot more memory), which is really not good for simple usecase like displaying messages in IM client :-/

[marczellm]

I'm on Windows where installation / compilation of separate binaries is more complicated. Maybe I'll fork QHangups for my own purpose and try QtWebEngine.

[xmikos]

If you try it with QtWebEngine and it will work without problems, I can merge it back, just do a pull request. I will have to try it myself, because QtWebKit clearly wouldn't be there forever (I just don't have time to do it right now).

[marczellm]

I tried QtWebEngine, but it dropped a lot of APIs including DOM manipulation (I found no clear source on this, but it only seems possible through injected JavaScript), so the migration is nontrivial.

[thecodrr]

I ran this: sudo apt-get install python3-pyqt5.qtwebkit in terminal and now everything works perfectly.

[marczellm]

Unfortunately I cannot do that on Windows.

But I created a pull request with the necessary changes to migrate to QtWebEngine. Unfortunately some APIs were removed, like scrolling or resizing signals.

It might be possible on windows to compile Qt with support for QtWebKit. At least on osx from homebrew there is a flag to do so.
