[Qt-interest] how to know derive class

[pengliang(彭亮)]

Hi all

See the picture bellow,  

QTableWidget: cellWIdget return a QWidget point, but I don’t know which QWidget is a QLineEdit, which is a QComboBox?

 

Now, snippets: convert QWidget to QLineEdit, if failed, then it’s a QComboBox.

But I think this is not good.

Anyone has good ideas?

 

         

 

 

 

Thanks

彭亮 Ken
