Qt 解析复杂对象构成 dumpStructure

如 QComboBox / QCalendarWidget / QSpinBox …

void Widget::Widget(QWidget* parent){auto c = new QCalendarWidget(this);dumpStructure(c,4);
}void Widget::dumpStructure(const QObject *obj, int spaces)
{qDebug() << QString("%1%2 : %3").arg("", spaces).arg(obj->metaObject()->className()).arg(obj->objectName());QObjectList list = obj->children();for (auto v : list) {dumpStructure(v, spaces + 4);}
}

输出
