Hello AntyaDev,
If you are using C++ also then you can put these line in main.cpp file.

@void setCenterOfApplication(QWidget* widget)
{
QSize size = widget->sizeHint();
QDesktopWidget* desktop = QApplication::desktop();
int width = desktop->width();
int height = desktop->height();
int mw = size.width();
int mh = size.height();
int centerW = (width/2) - (mw/2);
int centerH = (height/2) - (mh/2);
widget->move(centerW, centerH);
}@

this is another one
put these line in main.cpp file

@void center(QWidget &widget ,int WIDTH , int HEIGHT)
{
int x, y;
int screenWidth;
int screenHeight;

QDesktopWidget *desktop = QApplication::desktop();

screenWidth = desktop->width();
screenHeight = desktop->height();

x = (screenWidth - WIDTH) / 2;
y = (screenHeight - HEIGHT) / 2;

widget.setGeometry(x, y, WIDTH, HEIGHT);

this option is a more efficient!

@
void YourClass::centerWidget(QWidget *w, bool useSizeHint)
{
if(w->isFullScreen())
return;

QSize size;
if(useSizeHint)
    size = w->sizeHint();
else
    size = w->size();

QDesktopWidget *d = QApplication::desktop();
int ws = d->width();   // returns screen width
int h = d->height();  // returns screen height
int mw = size.width();
int mh = size.height();
int cw = (ws/2) - (mw/2);
int ch = (h/2) - (mh/2);
w->move(cw,ch);

}
