ui->verticalLayout->geometry()返回的QRect的left()和top()错误

 I add a verticalLayout to UI, and then calculate the QRect value of this region with the following code

QRect rc=ui->verticalLayout->geometry();

Then, I found that the QRect's top and left did not contain Toolbar's width and height.

So now I can only correct the wrong QRect with the following code:

QRect rc=ui->verticalLayout->geometry();

QRect rcMain=ui->centralWidget->geometry();

rc.setLeft(rc.left()+rcMain.left());

rc.setTop(rc.top()+rcMain.top());

rc.setRight(rc.right()+rcMain.left());

rc.setBottom(rc.bottom()+rcMain.top());
