[解决办法]
objectName()是获取对象的名称，setObjectName是给某一个对象设置名称，手册中有的呀
以下是从帮助手册中找到的，你自己看看吧
objectName : QString
This property holds the name of this object.
You can find an object by name (and type) using findChild(). You can find a set of objects with findChildren().
qDebug("MyClass::setPrecision(): (%s) invalid precision %f",
qPrintable(objectName()), newPrecision);By default, this property contains an empty string.
Access functions:
QString objectName () const
void setObjectName ( const QString & name )
See also metaObject() and QMetaObject::className().

手册有时你按F1提示你没有相关文档．这时候你可以先按住Ctrl然后点击你要查找的那个方法．跳到定义处后，然后在按F1一般就回有了．或者你直接在帮助里面搜索也可以的．
