DelegateModel, cant insert any object elements

masterofeye

Hello all,

i want to filter my model by a property provided also per property. remoteworkstations is a QList<QObject*> with my self definded object. These objects are registered for qml and visible by the debugger. My problem is the items.insert(entry, "test"); has no effect, even if I delete the "if" statement before the insert. Need the model to inherit from abstractmodel or something? Where is my failure?

import QtQuick 2.7
import QtQuick.Controls 2.0
import QtQml.Models 2.2

Item {
    width: parent.width
    height: parent.width
    id: root
    property var remoteworkstations
    property string projectname

    ListView {
        id: displayListView
        anchors.fill: parent
        spacing: 5
        model: displayDelegateModel
    }

    DelegateModel {
        id: displayDelegateModel

        delegate: MainSection{
            identifier: Hostname
        }
        model: remoteworkstations
        groups: [
            DelegateModelGroup {
            includeByDefault: false
            name: "test"
            }
        ]
        filterOnGroup: "test"
        Component.onCompleted: {
            var rowCount = remoteworkstations.length; //23
            items.remove(0,rowCount); //0
            for( var i = 0;i < rowCount;i++ ) {
                var entry = root.remoteworkstations[i]; //Entry visible in the debugger
                if(root.projectname === entry.AssignedProject.Projectname)
                    items.insert(entry,  "test"); //
            }
            console.log(items.count) //always 0
        }
    }

}

@masterofeye said in DelegateModel, cant insert any object elements:

remoteworkstations

Try to build entry with dummy js-object.

var entry = {
    prop1: "one",
    prop2: 2
};

Very important to make object corresponds other content of the model.
The is from the doc:
"Creates a new entry at index in a DelegateModel with the values from data that correspond to roles in the model assigned to DelegateModel::model."

Thx for answer but i got the same results.
When I try following, before i delete the item list

 var entry2 =items.get(0)

I should get the Item from the model. But the entry2 value hasn't any properties attached. I ecpect that i see the same results like in this row.

var entry = root.remoteworkstations[i];

@masterofeye

Doc about get()
So, try

var entry2 =items.get(0).model

I get what I want now, but the documentation for this not realy intuitive. I think there need's to be more examples, on how to set which property with which value.

Component.onCompleted: {
            var rowCount = RemoteWorkstations.length;
            for( var i = 0;i < rowCount;i++ ) {
                if( items.get(i).model.modelData.AssignedProject.Projectname === projectname) {
                     items.get(i).inTest = true
                }
            }
        }
