QT软件开发: 窗口打开固定在屏幕中间或者右下角

窗口打开默认在屏幕中间显示：

CameraWidget::CameraWidget(QWidget *parent, int index) :QWidget(parent),ui(new Ui::CameraWidget){ui->setupUi(this);//隐藏标题栏setWindowFlags(Qt::FramelessWindowHint);//无边框 //窗口显示在屏幕正中间QDesktopWidget *desktop = QApplication::desktop();move((desktop->width()-this->width())/2,(desktop->height()-this->height())/2);}

窗口打开默认在屏幕右下角显示：

CameraWidget::CameraWidget(QWidget *parent, int index) :QWidget(parent),ui(new Ui::CameraWidget){ui->setupUi(this);//隐藏标题栏setWindowFlags(Qt::FramelessWindowHint);//无边框 //打开的窗口在屏幕右下角QDesktopWidget *widget= QApplication::desktop();move(widget->width()-this->width(),widget->height()-this->height());}
