Passing additional parameters to QtSqlResult plugin

[lk]

Hi,

Suppose that One wants to pass additional parameters to a plugin implementation of QtSqlResult in a similar manner as the setForwardOnly parameter but for different info

Is there some generic method for adding parameters, or the base QtSqlResult class needs to be modified?

Also, that class appears to have

enum VirtualHookOperation { };
virtual void virtual_hook(int id, void *data);

enum VirtualHookOperation { };
virtual void virtual_hook(int id, void *data);

To copy to clipboard, switch view to plain text mode 

What is this hook used for?

Thanks
lk
