[static, deprecated] bool QMetaObject:: invokeMethod ( QObject * obj , const char * member , QGenericArgument val0 = QGenericArgument(0), QGenericArgument val1 = QGenericArgument(), QGenericArgument val2 = QGenericArgument(), QGenericArgument val3 = QGenericArgument(), QGenericArgument val4 = QGenericArgument(), QGenericArgument val5 = QGenericArgument(), QGenericArgument val6 = QGenericArgument(), QGenericArgument val7 = QGenericArgument(), QGenericArgument val8 = QGenericArgument(), QGenericArgument val9 = QGenericArgument())

This function is deprecated. We strongly advise against using it in new code.

Please use the variadic overload of this function.

此函數重載 invokeMethod()。

此重載援引成員使用連接類型 Qt::AutoConnection 並忽略返迴值。

This function is deprecated. We strongly advise against using it in new code.

Please use the variadic overload of this function.

此函數重載 invokeMethod()。

此重載可以被使用，若對成員的返迴值不感興趣。

This function is deprecated. We strongly advise against using it in new code.

這是重載函數。

Please use the variadic overload of this function

援引 member (信號或槽名稱) 在對象 obj 。返迴 true 若成員可以被援引。返迴 false 若沒有這樣的成員或參數不匹配。

See the variadic invokeMethod() function for more information. This function should behave the same way as that one, with the following limitations:

• The number of parameters is limited to 10.
• Parameter names may need to be an exact string match.
• Meta types are not automatically registered.

With asynchronous method invocations, the parameters must be of types that are already known to Qt's meta-object system, because Qt needs to copy the arguments to store them in an event behind the scenes. If you try to use a queued connection and get the error message

QMetaObject::invokeMethod: Unable to handle unregistered datatype 'MyType'
					

call qRegisterMetaType () 以在調用 invokeMethod() 之前注冊數據類型。

Constructs a new instance of this class. You can pass up to ten arguments ( val0 , val1 , val2 , val3 , val4 , val5 , val6 , val7 , val8 ，和 val9 ) to the constructor. Returns the new object, or nullptr if no suitable constructor is available.

注意，僅構造函數的聲明采用 Q_INVOKABLE 修飾符是可用的透過元對象係統。
