You can use the columnForeground component [1] for this purpose:
import QtQuick 2.3
import QtQuick.Controls 1.2
import QtQuick.Extras 1.2
import QtQuick.Controls.Styles 1.2
ApplicationWindow {
visible: true
width: 640
height: 480
title: qsTr("Hello World")
Tumbler {
id: tumbler
anchors.centerIn: parent
TumblerColumn {
model: 90
}
TumblerColumn {
model: 60
}
TumblerColumn {
model: 60
}
TumblerColumn {
model: ["N", "S"]
}
I don't think I would keep the N/S (or E/W) option in a separate column. Why
not integrate that into the first column?
Can you please elaborate? Do you mean create a model with 180 items ranging
from "N 0" to "N 90” and "S 0" to "S 90”?
Or 180 numbers and the delegate adds a “N” or “S” and subtracts 90 when needed?
You can easily use a delegate to on the column to display negative values as S
or W depending on latitude or longitude. To stick to a standard notation, you
would have to put the N/S/E/W first in the column, like S 17|33|08.
Using a delegate can also solve your model problem the whole thread started
with. Just use a number again as the model, but only use the positive range
from 0 to 360. Then in your delegate simply adjust the value from the model to
the actual value you want to display.
So a QML delegate can transform magic model numbers into real-world user
display data? For example a number 0 into “Apple”?
I am not sure I understand what delegates are operating on. In the case of a
TumblerColumn it would be the current index?
