@elfring said in Software development challenges around index creation for data models:

Will your data source work without hierarchies then?

I don't follow. This is a table model, there's no hierarchy here.

@Christian-Ehrlicher
ahh, you are right. Good catch.
http://doc.qt.io/qt-5/qjsonvalue.html#toDouble
converts the QJsonValue to double if its that type().
in this case it will return defaultValue (0)

so its something like

QJsonValue bid1 = jsonObj.value("bid_1"); QString asStr=bid1.toString(); double n = asStr.toDouble(); qDebug() << n;

@Geeva
The easies way is to move your task into its own function that expects q QList<QString> as an argument:

void myClass::myFunction(QList<QString> startvalue){ //do stuff eg: qDebug() << "Value Received from server :" << startvalue; QStringList first = startvalue.split("|"); int firstSize = first.size(); qDebug() << "size :" << firstSize; if(firstSize == 5){ first1 = first[2]; first2 = first[3]; }..........(continue) }

then you call that function for each and every item in your QList<QList<QString>>

QList<QList<QString> > myList for(QList<QString> ls : myList){ myFunction(ls); }

Seems I got a solution but no explication.

This test is passing everytime in release and debug...

function test_large_int_add0(data) { var act = 0xA5000000 + 0; var exp = '2768240640'; compare(act.toString(), exp); }

After some experimenting, the culprit was the MagnificationFilter. Although there were no problem setting the Magnification with QOpenGLTexture::NearestMipMapNearest with float images, with integer images, I had to set to QOpenGLTexture::Nearest.
