HTML frame doesn't show content

[dsanjurjo]

What is the bug or the crash?

In composer, when adding a HTML Frame, it doesn't show any content, neither by url or source.
I've tried in diferent versions (including a flatpak install), and none works.

I've a openSUSE system. First I tried with Tumbleweed, and then with Leap 15.6 (fresh install).

Launching Qgis from console, I get this log:

Creating a new Print Layout:

src/app/layout/qgslayoutdesignerdialog.cpp:4074 : (restoreWindowState) [17174ms] restore of layout UI geometry failed

And creating, filling (source) and refresing a new HTML Frame, no logs, but no content rendered neither.

I've deleted previous profile too.

Steps to reproduce the issue

Open Qgis
Create a new Print Layout
Create a new HTML Frame.
Fill source or select a URL
Press "Refresh HTML"

HTML Frame stays empty

@dsanjurjo, the HTML frame item is based on QtWebkit and it looks like that in both the openSUSE and the Flatpack builds of QGIS the use of QtWebkit is disabled.

See #58491, https://forums.opensuse.org/t/what-happened-to-libqt5-qtwebkit/148414, https://build.opensuse.org/projects/openSUSE:Factory/packages/qgis/files/qgis.spec, https://github.com/flathub/org.qgis.qgis/blob/9c0ec8ed22265ed68124fc3795dcf59e4aa87aa5/org.qgis.qgis.json#L72

[dsanjurjo]

So can I download WebKit (including dev libraries), Qgis srpm, and then recompile and rebuild the rpm for Qgis including WebKit support, or is it more complicated than this?

Or is there a repository where I can download qgis for openSuse with WebKit support (and to realize my wet dreams, a gdal library with ECW support too*)?

*I know (and did) how to rebuild gdal rpm with ECW support, but it is always easier if you find it done.

@dsanjurjo, QGIS distributed by Conda-forge has the QtWebkit support enabled.

Thanks, @agiudiceandrea . I'll give it a try.

We should show a user - visible warning when this functionality is disabled. The current approach definitely isn't user friendly!
