i created a class that has common code for all ui.
is there a generic paremeter which i can pass to the function to make it take any ui or i just have to override each function to take a different window.
ie ui::window1 *ui
footer( **** ui ****)
QPixmap cimage = QPixmap(":/images/OnOff.png");
each window inherits from the common class qobject.

One way to arrange this is make a pure virtual method in
commonthat will return a button pointer i.e.
virtual QPushButton* closeButton() = 0. then, in each derived class implement that method to return the button from its ui member. In your
commonclass access the button via
