QTableWidget with many cellwidgets update very slow!

[linxs]

I have a QTablWidget which has 10 columns and about 100-200 rows. Every row has 3 cellwidgets of QLabel type.
The problem is the qtablewidget udpate very slow, taking more than 5 seconds.
I want the update quickly.
How can I improve its performance??
ThankS!

Don't use cell widgets.

I want to implement customized drag and drop for item in qtablewidget, so I use qlabel as cellwidget.
If no use cellwidget, then what to use?

You don't need cell widgets to have custom drag and drop. QTableWidget already offers required facilities. Even more is offered if you use a proper model-view approach (i.e. QTableView nad QAbstractTableModel subclass instead of QTableWidget).
