Yes i am doing that. I am trying to close everything i know
i created (models, proxy models, context menus, delegates).
But the problem persists.

While inpecting the code i came to think that this class 
(QWindowsVistaStyle in current case) is not deleted when i close my 
table, but rather shared between multiple widgets. If i take
QStyle * s0 =  m_main_window->dockManager().style(); for example
where dockManager() is an unrelated QTreeView, the .text field in this
s0 contains .text from completely different QTableView (the one that
i am closing).

i have one widget right from start, this is the dockManager with the 
style s0. This widget is the first to create and therefore
i think it's the first to create the style via QStyleFactory. Some 
(all?) subsequent views seems to re-use this s0.

And then there is this QTableView that opens when tcp connection with 
data comes and closed on new connection with new data or user request.
