in this programm in mainwindow constructor i added timer and added SLOT (upd) with this.
on pushbutton clicked i did true the inc variable.
when inc will be true my timer will be start.In upd function value of x and y will be increase with 10 every time.
and now in paintevet i am passing update value of x and y so, button is moving. but i want every button will start to move when pushbutton will be click.
