Here is the code, I create 4 buttons. When one is clicked I wanna that its color changes to red and the color of all the others change to black.
But looks like I could not access the color
property.
Rectangle {
id: root
width: 200; height: 100
DelegateModel {
id: visualModel
model: ListModel {
ListElement { my_color: "red" }
ListElement { my_color: "black" }
ListElement { my_color: "black" }
ListElement { my_color: "black" }
}
groups: [
DelegateModelGroup { name: "selected" }
]
delegate: Rectangle {
id: item
height: 25
width: 200
color:my_color
MouseArea {
anchors.fill: parent
onClicked: {
console.log(visualModel.items.get(index).color)
for (var i = 0; i < root.count; i++){
if(index == i)
visualModel.items.get(i).color = "red";
else
visualModel.items.get(i).color = "black";
}
}
}
}
}
ListView {
anchors.fill: parent
model: visualModel
}
}

I advice you to use ExclusiveGroup
from QML controls. Usually it is used for Action
but it's possible to use it for any other Item
. From the Qt docs:
It is possible to add support for ExclusiveGroup for an object or control. It should have a checked property, and either a checkedChanged, toggled(), or toggled(bool) signal.
So all we need is to add suitable property. Small example:
import QtQuick 2.5
import QtQuick.Window 2.0
import QtQuick.Controls 1.4
Window {
width: 200
height: 400
ExclusiveGroup { id: exclusiveGroup }
ListView {
anchors.fill: parent
anchors.margins: 5
spacing: 2
model: 10
delegate: Rectangle {
id: myItem
property bool checked: false // <-- this is necessary
height: 30
width: parent.width
color: myItem.checked ? "lightblue" : "#DEDEDE"
border { width: 1; color: "#999" }
radius: 5
Text { text: "item" + (index + 1); anchors.centerIn: parent}
MouseArea {
anchors.fill: parent
cursorShape: Qt.PointingHandCursor
onClicked: myItem.checked = !myItem.checked;
}
Component.onCompleted: {
exclusiveGroup.bindCheckable(myItem);
}
}
}
}
