Hi,

You can use code like this:
@
QVariant getVaraintObect() //This method must have prototype with Q_INVOKABLE macros in you C++ class.
{
QVariantMap map;
map["key1"] = list; //your QVariantList object with items.
map["key2"] = 20; //your int value.
//....
return QVariant(map); //The method return QVariant object.
}
@

In QML you call the method of your class which must to return to you your QVaraint object, for example:
@
Text {
text: yourCPPObject.getVaraintObect().key2.
}
@

In result you must see 20 in Text element of your QML file.
Also you can use console.log to print all structure of object:
@
console.log(yourCPPObject.getVaraintObect());
@

In result you must must see something like this:
@
{"key1": [], "key2": 20}
@
