Accessing Qlist within a Qlist and Deallocating them through Qml

[sruthihsr]

Hi All,
I have the following classes
@
class SourceSinkObj : public QObject
{
Q_OBJECT
Q_PROPERTY(QString name READ name WRITE setName NOTIFY nameChanged)
Q_PROPERTY(QString color READ color WRITE setColor NOTIFY colorChanged)
}
@
and
@
class ListofLists : public SourceSinkObj
{
Q_OBJECT
Q_PROPERTY(quint32 ID READ ID WRITE setID NOTIFY IDChanged)
Q_PROPERTY( QList<SourceSinkObj*> sublist READ sublist WRITE setsublist
@
In my main .cpp
I have the following where listSinkClasses is a Vector
@
QList<ListofLists*> SinkMasterlist;
for (int i=0 ;i < listSinkClasses.size() ;i++)
{
am_SinkClass_s tempSinkClass;
tempSinkClass= listSinkClasses.at(i);
ListofLists* TempSinkMaster = new ListofLists();
quint32 TempID= tempSinkClass.SinkClassID;
TempSinkMaster->setID(TempID);
SinkMasterlist.append(TempSinkMaster);

}
@

Please let me know
1 How do i iterate through the Qlist in Qml
2.How do i deallocate memory on button click in qml. As the function to deallocate would be in main .cpp I can not use Q_INVOKABLE

Thanks and Regards
