Create QML Items out of DelegateModel - qt

Question

Is it possible to create QML Items out of a DelegateModel?
Here is a example DelegateModel:
DelegateModel
{
id: delegateModel
model: ListModel
{
ListElement { name: "#FAFAFA"; test: "object1" }
ListElement { name: "#000000"; test: "object2" }
}
delegate: Rectangle
{
objectName: test
width: 50
height: 50
color: name
}
Component.onCompleted:
{
Utils.var_dump(items,3)
items.create(0)
Utils.var_dump(items.get(0),3)
}
}
The Result should look like this:
Rectangle
{
objectName: "object1"
width: 50
height: 50
color: "#FAFAFA"
}
Rectangle
{
objectName: "object2"
width: 50
height: 50
color: "#000000"
}
For every ListElement there is a created delegate with the inserted ListElement data.

You can do that with anything that is usable to instantiate a Model (a View)
For example you could use it as a model for a ListView, a GridView or a Repeater. As the model provides the delegate on its own, you do not need to specify any delegate in the View, that instantiates it.
Column {
Repeater {
model: delegateModel
// delegate: ... <--- Nothing here! Uses the delegate from the Model.
}
}
If you use the create(index)-Method, the delegate will be created, but has no parent, so it is not displayed. So you need to set the parent, to have it shown:
Button {
onClicked: {
for (var a = 0; a < dm.items.count; a++) {
var o = dm.items.create(a)
o.parent = r
}
}
}
You need to be aware, that the DelegateModel (without Package and Parts) can't be used in multiple views, as each entry/delegate can be instantiated only once at the same time. If you want to have that,
consider using a QSortFilterProxyModel to filter the stuff, and use as much Views that provide their own delegates, as you want.
