How can I make the child control display more area than the parent control?

HuXiaoer

auto btn = new QPushButton(parent);
btn->setFixedSize(100,100);
auto lab = new Qlabel(btn);
lab->setFixedSize(200,200);
lab->setStyleSheet("color:#000000");

How can I make the child control display more area than the parent control?
I expect the result to be a 200X200 black area,and btn is below lab.

@HuXiaoer You can't. Child is inside parent and as such it can't be bigger than its parent.

@jsulm ok!~ Thank you for your answer.

Hi,

@jsulm correctly noted, your child can't be bigger than your parent however you can use a QScrollArea to put more widgets in the child and then scroll through it to show the ones you want.
