Dynamically create ListModel in QML

Question

When I need to create any QML component in runtime, I can use that guide: http://qt-project.org/doc/qt-5/qtqml-javascript-dynamicobjectcreation.html

i.e. just call Qt.cr

Answer 1

I do the initialization like this:

dataObject_m1.initSystem= function() { // QML calls when ready 
  console.log( "ModulData_1.js func initSystem()");

  dataObject_m1.statisticsSystem= Qt.createQmlObject("import QtQuick 2.5; ListModel{}", dataObject_m1.parent, "dynamic_source" );
  dataObject_m1.statisticsSystem.objectName = "ModelSystem";
  dataObject_m1.statisticsSystem.append( { name: qsTr("System"), number: "", val: ""});
  dataObject_m1.statisticsSystem.append( { name: "S3500", number: "", val: ""});
  dataObject_m1.statisticsSystem.append( { name: "S3550", number: "", val: ""});
  dataObject_m1.statisticsSystem.append( { name: "S3551", number: "", val: ""});
  dataObject_m1.statisticsSystem.append( { name: "S9999", number: "", val: ""});
}    

And to update Data:

 var updateSystem = function ( numberMap , valMap) {
     console.log ("ModuleData_1.js: updateSystem" );

   for (var num in (numberMap )) {
      var j = dataObject_m1.idMap[num];
      dataObject_m1.statisticsSystem.set( j, { val : Map[num]});
      console.log ("number(" + numberMap[val]+ ") [" + String(j) + "]= numbeMap["+val+"]" )
  }
 for (var valx in (valMap)) {
     var k = dataObject_m1.idMap[valx];
     dataObject_m1.statisticsSystem.set( k, { bad : valMap[valx]});
     console.log ("val(" + valMap[valx]+ ") [" + String(k) + "]= valMap["+valx+"]" )
  }
}

Access fuction to model:

 var statisticsModelSystem= function()  {
    console.log ("ModulData_1.js: get statisticsModelSystem" );
    if ( typeof(dataObject_m1.statisticsSystem) !== 'object')
        console.error(" statisticsSystem is undefined ")

    return dataObject_m1.statisticsSystem;
}
