I have managed to fix data in TumblerColumn with JS and Component
TumblerColumn {
id: lastCheckDay
Component.onCompleted: {
var days = [];
for (var i = 1; i <= 31; ++i) {
days.push(i);
}
lastCheckDay.model = days;
}
}
this way allows me to change values for TumblerColumn without Delegate and that is why I am not loosing QT styles
I will this answer here, maybe it can be helpful for someone
