[Qt-interest] Memory Management in Qt

[Ramesh]

Thanks konrad,

Ok, so all the widget by default will have a first parameter as parent, so
if we specify the parent
We don't need to bother about deletion of the widget right..

The listview is owned by its parent widget - you do not need to delete it.

The QStandardItemModel takes an optional first parameter: the parent. If it
has a parent it will be deleted automatically when the parent is deleted. I
usually let models be owned by the same widget as the *view it is used by -
this way they are cleaned up together.
