This-> resize (150,150); // form size
// Center the form
Q1_topwidget * desktop = qapplication: desktop ();
Int width = desktop-> width ();
Int Height = desktop-> height ();
Move (width-this-> width ()/2, (height-this-> height ()/2 );

PS: The resize should be placed before the position of the adjustment form. Otherwise, the current this-> width () and this-> height () are the default values, and the center is not guaranteed after the adjustment.
