assertion failed: Signal and slot arguments are not compatible error - I need help understanding the error "arguments'

I really wonder what's so hard to read the examples and documentation. You can not mix new and old signal/slot syntax...

As we have said many times, you must not mix new style connection syntax (&QPushButton::clicked) with old style syntax (SLOT(&TabWidget_Chat::EmptyTestSlot()) in oneconnect(). Since you often have problems in this area, we have said you should stick to new style only, I do not know why you use a mixed old style here as it is so easy (and better) to use new style only.
