Use the Repeater element to Create a Listmodel with various ListElements

[smeik]

Hi,
I hope someone can Help me. I have a ListModel and I want to fill it automatically with
ListElements. All the ListElements have a name and an info property. I also have two Arrays that store the name and info values.
Is there a way to do this? maybe by using the Repeater?

Thanks in Advance for helping me.

@smeik why do you want to do that?

You can use your arrays directly as models without ListModel, they won't have any roles though.

@GrecKo I use dictionaries inside lists. So my "roles" look like this:

[
{name: "Fred"}
]
...
modelData.name

@GrecKo
Thanks. Do you have an example how to do this?

You can also use some JavaScript to fill your ListModel

function filllListModel()
{
  for(int i = 0; i < JavaScriptArrayName.length; i++)
  {
    myListModel.append(  JavaScriptArrayName[i]  );
  }
}

@smeik something like this :

ListView {
    model: [
        { foo: "hello", bar: "red" },
        { foo: "world", bar: "orange" }
    ]
    delegate: ItemDelegate {
        text: modelData.foo
        color: modelData.bar
    }
}

Alternatively you could use JsonListModel from https://github.com/benlau/qsyncable if you want to transform a js array to a proper QAbstractListModel

JsonListModel {
    id: myModel
    source: [
        { foo: "hello", bar: "red" },
        { foo: "world", bar: "orange" }
    ]
}    
ListView {
    model: myModel
    delegate: ItemDelegate {
        text: model.foo
        color: model.bar
    }
}
