Hi Fabian,
thanks for the feedback.
QGuiApplication::setPalette works mostly.
It doesn't allow me to change the theme/palette after the QML file has
been loaded (as mentioned here
https://doc.qt.io/qt-5/qml-qtquick-controls2-applicationwindow.html#palette-prop)
This approach also makes selecting the theme or editing and reloading
the theme impossible.
Also the ButtonText doen't use the new palette and stays black (I'm
using the Fusion theme).
I don't really mind the new way. I just wanted to know if I had to
change it or it might be working again later and I have changed it for
nothing
since it would be up to 60 properties (20 ColorRoles with 3 ColorGroups,
although I'll probably be ignoring the Inactive group).
I just tested the new QQuickPalette and I think I found a bug:
This works fine:
palette{
active{
buttonText:Theme.buttonText
}
disabled{
buttonText:Theme.buttonTextDisabled
}
}
But this does ignore the disabled text color:
palette{
buttonText:Theme.buttonText
disabled{
buttonText:Theme.buttonTextDisabled
}
}
And this also works:
palette{
buttonText:"orange"
disabled{
buttonText:Theme.buttonTextDisabled
}
}

Hi Marcel,
as Vitaly mentioned, palette was never explicitly documented to be a
QPalette.
We're currently discussing internally whether we still want to support
binding a QPalette property
to a palette QML property in Qt 6; and if yes, how to do it.
We'll provide an update (+ justification) once we've come to a decision.
What should work (both in 5.x and 6.0) is to use
https://doc.qt.io/qt-5/qguiapplication.html#setPalette
Does that functionality cover your use case?

*Betreff:* [Development] Qt 6: Assigning QPalette to
ApplicationWindow.palette no longer supported?
Hi,
I recently implemented a theming system for my Qt Quick application.
With Qt 6 I'm getting an error: "Unable to assign QPalette to
QQuickPalette*"
This was changed in the following commits:
- https://codereview.qt-project.org/c/qt/qtquickcontrols2/+/270097
- https://codereview.qt-project.org/c/qt/qtdeclarative/+/270092
My Theme class looks like this:
class Theme : public QObject
{
Q_OBJECT
Q_PROPERTY(QPalette palette MEMBER _palette NOTIFY themeChanged)
...
};
In my main.qml I'm setting the palette with:
ApplicationWindow {
palette: Theme.palette
...
}
My question is:
Is my use case no longer supported or is this a regression?
And if not, what is the proposed way to do it? Preferrably compatible
with Qt 5.15 and Qt 6.
Do I have to set every single colorrole of the palette separately?
E.g.
ApplicationWindow {
palette {
active {
buttonText: Theme.buttonText
button: Theme.button
...
}
disabled {
buttonText: Theme.buttonTextDisabled
button: Theme.buttonDisabld
}
}
}
Kind regards,
Marcel
