No WebView plug-in found!
-
Hi,
I made a simple crawler using Qt 5.15.0 and QML.
It works properly when launched from QtCreator.
But when I run it standalone, it doesn't work.I ran windeployqt for sure, (--release --qmldir d:\qt\5.15.0...\qml)
and manually copied the QtWebView qml folder.
But it still doesn't work. So I activate the console.
It said, No WebView plug-in found!So I copied all of qml, plugins, and dlls into the release folder.
I also added QT += webengine configuration.I have no idea what to do anymore.
OS: Windows 10
SDK: Qt 5.15.0 MSVC2019 x64
Compiler: MSVC2017 (not 2019)Can someone help me?

@Pearled
I do not know whether there is any difference because this is QML, but the normal first course of action for a Qt missing plug-in problem is to invoke your executable from a shell where you have previously typed in:set QT_DEBUG_PLUGINS=1This should cause trace output into the terminal showing where Qt is looking for what (provided this works for QML, as I said).
