How to create different component base on ListModel in QML - qt

Question

There are 9 parameters that I need to use TextField1 to input value.
So I use
ListModel lstPara {
ListElement{
text:"A";value:"123"
}...(9 Elements)
}
Grid{
id: grid
anchors.fill: parent
columns: 3
spacing: 5
Repeater {
id: rpPara
model: lstPara
delegate: TextField1 {
}
}
}
But now there is a parameter that i need to use in another QML type to set the value, all others are used in TextField1.
I tried to define ListModel like this
ListModel lstPara{
ListElement {
text: "A";
type: 1";
value: "123"
}
ListElement {
text: "B";
type: 2";
value: "321"
}
...(9 Elements)
}
Grid{
id: grid
anchors.fill: parent
columns: 3
spacing: 5
Repeater {
id: rpPara
model: lstPara
(some code : like this)
delegate: {
return type === 1 ?
TextField1 {
}
:
another QML type {
}
}
}
}
The code above can not run.
And I don`t want to write 8 TextField1 and 1 another QML type.
So, is there a way to use ListModel?

You can't directly use an Item declaration in a conditional expression like that, but you can do it with a Component. Here's an example of how to do it using a Loader as your delegate, and choosing which Component to load based on the model:
ListModel {
id: lstPara
ListElement {
text: "A"
type: 1
value: "123"
}
ListElement {
text: "B"
type: 2
value: "321"
}
}
Grid {
id:grid
anchors.fill: parent
columns: 3
spacing: 5
Repeater {
id: rpPara
model: lstPara
delegate: Loader {
sourceComponent: type === 1 ? someText : otherText
onLoaded: {
item.text = text
item.value = value
}
}
}
Component {
id: someText
Text {
property string value
color: "blue"
}
}
Component {
id: otherText
Text {
property string value
color: "red"
}
}
}
