Re: [QGIS-Developer] Transition from QtWebKit to QtWebEngine in qgis2web (QGIS plugin)

[Julien Moura (Oslandia) via QGIS-Developer]

Hi Andrea,

We're currently working on this question on QTribu (https://github.com/geotribu/qtribu/pull/186).

What is the correct way to have users install the qtwebengine dependency?

On Debian and derived: |sudo apt install python3-pyqt5.qtwebengine|


|

Hope it helps,
Julien

On Windows, it seems that it's already included in the MSI package and standard QGIS installation with OSGeo4W.|

Good morning developers,
I managed to get qtwebengine working in qgis2web.


    self.preview.setMinimumWidth(650)

*Request:*
What is the correct way to have users install the qtwebengine dependency?


    try:
            if system == 'Windows':
                pip_exec = os.path.join(sysconfig.get_path("scripts"),
    "pip3")
                env = os.environ.copy()
                if full_proxy_url:
                    env['http_proxy'] = full_proxy_url
                    env['https_proxy'] = full_proxy_url
                subprocess.check_call([pip_exec, "install",
    "--upgrade", "PyQtWebEngine==5.15.6"], env=env)
            elif system == 'Linux':
                subprocess.check_call(["sudo", "apt-get", "install",
    "python3-pyqt5.qtwebengine"])
            elif system == 'Darwin':  # macOS
                subprocess.check_call(["brew", "install", "pyqt5"])



Many thanks

Thanks Jan Dalheimer
Thanks Jean-Baptiste Peter

From your answers I understood many things.







*The clue:*


For now I noticed this:




2) 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



3) 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


Thank you all

For some reason qtwebkit didn't need to set a window width while qtwebengine did, so with this code I solved it I wrote this code and it works fine but I only tested it on windows. Is this the correct way? OggettoRe: [QGIS-Developer] Transition from QtWebKit to QtWebEngine in qgis2web (QGIS plugin) I tried both to use QGIS 3.38.0 installed in win10 via .msi and the version via OSGeo4W setup; In the first case I added qtwebengine via "pip install qtwebengine", in the second case I installed the "python3-pyqtwebengine" package via OsGeo4w setup In both installations I get the same result: QtWebEngine it does not work well I also tried to create a new test plugin and I get the same result, I can't even view a web page. Is there an example of a basic plugin that I can see? Or can someone create it? If I use qt designer to insert a QtWebEngineView into the plugin graphics it works well, even when setting a static web page. But if I open QGIS that plugin won't work, why does this happen? I would therefore think that it is just a question of dependency . 1) From QGIS version 3.38.0 I can use "from qgis.PyQt.QtWebEngineWidgets import *" instead of "from PyQt5.QtWebEngineWidgets import *"
