Qt编程 窗口居中显示

Qt编程技巧 窗体居中显示 
view plaincopy to clipboardprint?
this->resize(150,150); //窗体大小
//窗体居中
QDesktopWidget* desktop = QApplication::desktop();
int width = desktop->width();
int height = desktop->height();
move((width - this->width())/2, (height - this->height())/2);

PS:resize要放在调整窗体位置前面，不然刚开始的this->width()和this->height()是默认的，再调整就不能保证是居中了
