[Qt-interest] Show QTableView is a very slow?

[Alexandre Beraud]

Hi,

We can't give you any answer without some more information. Did you 
derive the QTableView class ? Do you have big calculations in its 
showEvent() ? Do you use a QItemDelegate with a heavy paintEvent() ? Did 
you connect the
tab change to one or several slots ?

Regards,

Alex
