after subclassing will the inbuild signals work

[babu198649]

hi
i have subclassed the qlistview class to receive mouse double click event .
after this the inbuild signal for double click(doubleClicked(QModelIndex) has no effed.

i have even tried ignoring(event-.ignore) the event inside the mouse doubleclick
event function(which is subclassed)

so if a function is subclassed does the inbuild signals stop functioning.

if you want only to extend functionality available in the base class, you can add in your subclass implementation the base class version call:

void DerivedClass::methodName()
{
    BaseClass::methodName(); //base class functionality
    // your own extended functionality code
}

void DerivedClass::methodName()
{
    BaseClass::methodName(); //base class functionality
    // your own extended functionality code
}

To be precise - you have to add it.
