Hi, your question unblocked me.
I'm using my "qgis2web" plugin and your "layer atlas" plugin in a laptop
with integrated (not dedicated) video card and that's why I get white screen
when I use our plugins. Using them on a desktop PC with a dedicated video card
both work.
Taking inspiration from the "HERE Maps for QGIS" plugin which works well on
my laptop and which uses QtWebEngine, I understood that to make our plugins
work we need to add a setting.
In Layer_Atlas_dockwidget.py file edit:
from PyQt5.QtWebEngineWidgets import QWebEngineView, QWebEngineSettings
and add WebGLEnabled settings:
class CustomWebEngineView(QWebEngineView):
def __init__(self, *args, **kwargs):
super(CustomWebEngineView, self).__init__(*args, **kwargs)
settings = self.settings()
settings.setAttribute(QWebEngineSettings.WebGLEnabled, True)
Your plugin will work perfectly even on PCs without a dedicated video card.
Now you should configure automatic installation of the dependency in case it
is not there. This way all users, even those who install via .msi, will be able
to use your plugin. Always take inspiration from the "Here" plugin, I still
have to finish the code but I'm almost done.
Congratulations for the plugin, it works great and I think it is very useful.

This is head spinning! For OSGeo4W install with "python3-pyqtwebengine"
selected, are you testing this in a VM? I wonder if the crash at startup may be
caused by the fact that qwebengineview is using opengl which is not working
with emulated graphics. This works on my desktop.
I am sure for the .msi installer and will have to do further research.
Best,

Since version 3.38.0 the QtWebEngine export has been added back to qgis.PyQt
as you can see here:
https://github.com/qgis/QGIS/blob/final-3_38_0/python/PyQt/CMakeLists.txt
So by installing the standard QGIS .msi just add the dependency via "pip
install QtWebEngine" and then use "from qgis.PyQt.QtWebEngineWidgets"
In any case I just installed QGIS in win10 from the OSGeo4W installer adding
only the "python3-pyqtwebengine" dependency and your plugin doesn't work.
Crashes QGIS startup.
Maybe do some testing on new installations.
As for me, since I believe that most users use qgis via the .msi
installation, not via OSGeo4W, it is important for me to understand what to
have users install and my goal, when I will at least be able to start my
plugin, will be to try to automate these dependencies.
Isn't it the same for you? How do you solve this "problem"?
For now I noticed this:
with qgis 3.38.0 .msi installation this dependency is missing:
qt5-devel (5.15.13-1)
Qt5 headers and libraries (Development)
Required by: python3-pyqtwebengine
with OSGeo4W setup these dependencies are required:
python3-core (3.12.4-1)
Python core interpreter and runtime
Required by: python3-pyqtwebengine, python3-pyqt5, python3-pyqt5-sip
python3-pyqt5 (5.15.10-1)
Python bindings for the Qt cross platform application toolkit
Required by: python3-pyqtwebengine
python3-pyqt5-sip (12.13.0-1)
The sip module support for PyQt5
Required by: python3-pyqtwebengine, python3-pyqt5
qt5-devel (5.15.13-1)
Qt5 headers and libraries (Development)
Required by: python3-pyqtwebengine
qt5-libs (5.15.13-1)
Qt5 runtime libraries
Required by: python3-pyqtwebengine, python3-pyqt5, qt5-devel, qtwebkit-libs

Plugin
Did you install PyQtWebEngine “manually” using pip install? If that is the
case, it will not be bundled with qgis and needs to be imported from Pyqt
directly:
‘from qgis.PyQt.QtWebEngineWidgets import QWebEngineView’
needs to be replaced by :
‘from PyQt5.QtWebEngineWidgets import QWebEngineView’
As of now, the only way to get this working out of the box is to install
qgis with Osgeo4W installer.

I don’t think this will work with qgis installed using .msi as the installer
does not include PyQtWebEngine.
It should work out of the box using qgis osgeo4W installer which includes
the latest version of PyQtWebEngine (5.15.6) which is required for the plugin
to work. There should not be any other dependencies.

In a clean install of QGIS 3.38.0, installing the package via the zip
downloaded from github, the plugin does not work. The icon is not visible and
if I close and reopen QGIS it does not start.
No message in python console.
What additional dependencies does it need?
I use win10 and I installed QGIS via .msi

Oggetto [QGIS-Developer] Request for Initial Feedback on Layer Atlas Plugin
Dear Developers,
I have been experimenting for a while with QWebEngineView which opens a lot
of possibilities for plugin development and started to implement a new plugin
to explore and share layers directly from QGIS by simply dragging and dropping
them from the layer panel.
Here is a short screen recording to see how it works:
https://www.youtube.com/watch?v=k5k74faBJKo
As there are a few things remaining to do, the plugin not yet uploaded to
the plugin repo but it is mostly functional. Initial feedback from interested
testers would be very useful!
Here is the GitHub repository to try it out:
https://github.com/jbp35/layer-atlas-plugin/
Thank you for your time and assistance!
Best regards,
Jean-Baptiste Peter
