How to deal with QML-based Qt6 #10

Open tio-trom opened 1 year ago

tio-trom commented 1 year ago

From my tests one needs to add the export QT_QUICK_CONTROLS_STYLE=gtk2 variable in order to theme the QML-based QT apps. Works for QT5 but for QT6 it will make the apps fail to launch the GUI with errors like: 

[Warning] (Thu Sep 28 04:14:09 2023): QQmlApplicationEngine failed to load component
[Warning] (Thu Sep 28 04:14:09 2023): qrc:/gpt4all/main.qml: module "gtk2" is not installed
[Warning] (Thu Sep 28 04:14:09 2023): QIODevice::read (QNetworkReplyHttpImpl): device not open
[Warning] (Thu Sep 28 04:14:09 2023): ERROR: Couldn't parse:  "" "illegal value"

What's the solution?

Thanks

Unfortunately, QStyle is not supported by QML. Try to use QQC2-Desktop-Style from KDE: https://api.kde.org/frameworks/qqc2-desktop-style/html/index.html

export QT_QUICK_CONTROLS_STYLE=org.kde.desktop

That didn't seem to make any difference.... I added export QT_QUICK_CONTROLS_STYLE=org.kde.desktop but it does not change anything. So basically qt6gtk2 cannot theme the QML-based Qt6 nor is there an easy way to do it?

Unfortunately, I do not know about other solution.
