How to resize frameless QWidget?

sonichy

Only a QLabel in a frameless QWidget.
When font turns from small into big, the widget can expand without resize.
When font turns from big into small, the widget can not shrink with resize!

widget->setWindowFlags(Qt::FramelessWindowHint);
widget->ui->label->setFont(font);
widget->ui->label->adjustSize();
widget->resize(widget->ui->label->size());

@sonichy said in How to resize QWidget to fit QLabel?:

widget->resize(widget->ui->label->size());

i guess should be

widget->resize(widget->ui->label->sizeHint());
