QT中inherits（）函数可 判断一个对象的类是不是从另外一个类继承而来

函数原型 bool QObject::inherits ( const char * lname ) const

//来自官方文档

QTimer *timer = new QTimer; // QTimer inherits QObject

  timer->inherits("QTimer");          // returns true

  timer->inherits("QObject");         // returns true

  timer->inherits("QAbstractButton"); // returns false

  // QVBoxLayout inherits QObject and QLayoutItem

  QVBoxLayout *layout = new QVBoxLayout;

  layout->inherits("QObject");        // returns true

  layout->inherits("QLayoutItem");    // returns true (even though QLayoutItem is not a QObject)
