[Qt-interest] QList and QUrl problem

[ice stone]

I am trying to figure out a problem involving QList<QUrl>. Here is my code:
 
 QList<QUrl> test;
 QUrl url;
 url.setUrl("1");
 test.append(url);
 qDebug()<<test[0];
 url.setUrl("2");
 test.append(url);
 qDebug()<<test[0];
 url.setUrl("3");
 test.append(url);
 qDebug()<<test[0] << test[1] << test[2];

 
And the output is:
 QUrl( "1" )  
 QUrl( "2" )  
 QUrl( "3" )   QUrl( "3" )   QUrl( "3" )
 
My understanding of QList is that it allocates a memory in heap for every inserted item and delete them when they are removed from the list. But the output here seems to point to a single QUrl object for all three items. Anyone can help me to solve this puzzle? Thanks a lot.
 
Yan
