Context menu works slowly on QTableWidget

[THRESHE]

QTableWidget's cells are always painted with delegates

What about index Widgets ?

I suggest using a profiler to find a bottle neck

What's that ?

What about index Widgets ?

They are separate widgets so essentially they don't count. Even then the delegate is used. Try setting a transparent index widget and you'll see for yourself.

What's that ?
