qt窗口坐标

新建一个mainwindow的工程，运行。

 

 窗口的坐标：

代码：

//窗口左上角的位置(含边框)
    qDebug() << "1(含边框):" << this->frameGeometry().x() << this->frameGeometry().y();//1
    qDebug() << "2(含边框):" << this->x()  << this->y();//2
    qDebug() << "3(含边框):" << this->pos().x() << this->pos().y();//3
    //窗口的宽度和高度(含边框)
    qDebug() << "4(不含边框):" << this->frameGeometry().width() << this->frameGeometry().height();
    //窗口左上角的位置(不含边框)
    qDebug() << "5(不含边框):" << this->geometry().x() << this->geometry().y();
    //窗口的宽度和高度(不含边框)
    qDebug() << "6(不含边框):" << this->geometry().width() << this->geometry().height();//1
    qDebug() << "7(不含边框):" << this->width() << this->height();//2
    qDebug() << "8(不含边框):" << this->rect().width() << this->rect().height();//3
    qDebug() << "9(不含边框):" << this->size().width() << this->size().height();//4

输出：

1(含边框): 989 578
2(含边框): 989 578
3(含边框): 989 578
4(不含边框): 902 519
5(不含边框): 1002 636
6(不含边框): 876 448
7(不含边框): 876 448
8(不含边框): 876 448
9(不含边框): 876 448
