[Qt-interest] Question regarding pointer parameters in functions

[Patric]

Yes, sure it deallocates all the memory by destruction. But the question is, 
is the method who is adding items takes care of the allocation.
Take for example this method :
void QStatusBar::addPermanentWidget ( QWidget * widget, int stretch = 0 )

If we add 5 widgets like this :

addPermanentWidget(new QLabel("testLabel1"));
addPermanentWidget(new QLabel("testLabel2"));
addPermanentWidget(new QLabel("testLabel3"));
addPermanentWidget(new QLabel("testLabel4"));
addPermanentWidget(new QLabel("testLabel5"));
http://doc.trolltech.com/4.5/qstatusbar.html#addPermanentWidget

will it take care of the first 4 ? Is the method smart enough to delete the 
memory of the old element, before add the new element.

The same question for this one, ofcourse :

void QStandardItemModel::appendRow ( QStandardItem * item )

Patric
