Qt 6 No WebView plug-in found!

Augustas

Hello,
I'm trying to use WebView in a Qt Quick app on Qt 6.3. The app compiles, however I get a "No WebView plug-in found!" error in the console and WebView object is blank.

When installing Qt 6.3, in the maintainance tool, I've selected:

MSVC 2019 64-bit
Qt WebEngine
QtWebView
Qt Debug Information Files

I have tried calling QtWebView::initialize(); before and after creating QGuiApplication .

I have Qt += webview in my pro file. I've also tried adding QT_DEBUG_PLUGINS=1 as recommended in No WebView plug-in found! , however that doesn't fix the error nor does that provide any additional info in the console.

The WebView works fine on Qt 5.14.2 and Qt 5.15.2. I can't get it to work on Qt 6.2.4 or on Qt 6.3.

I've also checked Qt/6.3.0/msvc2019_64/lib folder, and Qt6WebView libs seems to be present there.

After checking Qt WebView documentation I assume that WebView is supported on Qt 6. Any ideas on what could be wrong?

You might need to install Qt Positioning too: https://bugreports.qt.io/browse/QTBUG-102997

@JKSH Installing Qt Positioning packet in Maintainance Tool seems to fix the issue :) Thank you!

edit: Just to add to your answer: it seems that you also need to install Qt WebChannel packet for WebView to work. So in total you need to install:

Qt WebEngine
Qt Positioning
Qt WebChannel
Qt WebView

Good catch. Thanks for letting us know!

(I didn't notice it before because I usually install everything, for convenience)
