Calling method from modelData

Pantoufle

Hello,

I'm currently displaying a QStringList via a ListView like this (SvgIconLoader is a custom component ) :

ListView {
        spacing: 5
        anchors.fill: parent
        anchors.top: parent.top
        anchors.topMargin: 25
        model: mygui.getMyList // A QStringList
        delegate:
            RowLayout {
                anchors.left: parent.left
                anchors.leftMargin: 25
                spacing: 20
                SvgIconLoader {
                    id: myIcon
                    icon : "qrc:/Ressources/images/test.svg"
                    size: 40
                }
                Text {
                    text: modelData
                    font.pixelSize: 24
                    color: "white"
                }
            }
    }

This code works perfectly. Now I'm trying to add a feature, I would like when the QString contained in "modelData" contains for example the letter "E", then it changes the color of the text to green.

So I tried this:

color: modelData.contains("E") ? "green" : "white"

But it doesn't seems to work.
My question is, can we call QObject method from a modelData? If not, is there a solution to this problem?

~~What you have should be working.~~ Are you getting errors in the Application Output window?

Edit: Hmmm, in a simple test contains is not working.
"TypeError: Property 'contains' of object Erp is not a function"

Edit: Use indexOf instead (cause javascript I guess, not all QString stuff is supported):

property var vstr: "Erp"
property bool vbool: "%1".arg(vstr).indexOf("E") !== -1

it works, thanks a lot !

On the other hand, I find it odd that we are only entitled to certain methods, we have to guess them?

the string inside qml is not a QString object, but IIRC a JS string, that one does not have the contains function

Thank you for helping me understand.

Have a nice day
