[deprecated] bool QMetaMethod:: invoke ( QObject * object , Qt::ConnectionType connectionType , QGenericReturnArgument returnValue , QGenericArgument val0 = QGenericArgument(nullptr), 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()) const

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

Please use the variadic overload of this function

Invokes this method on the object object 。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 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

QMetaMethod::invoke: Unable to handle unregistered datatype 'MyType'
					

call qRegisterMetaType () to register the data type before you call QMetaMethod::invoke ().

警告： In addition to the limitations of the variadic invoke() overload, the arguments must have the same type as the ones expected by the method, else, the behavior is undefined.

另請參閱 Q_ARG (), Q_RETURN_ARG (), qRegisterMetaType ()，和 QMetaObject::invokeMethod ().

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

Please use the variadic overload of this function

This function overloads invoke().

This overload invokes this method using the connection type 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

This function overloads invoke().

This overload always invokes this method using the connection type Qt::AutoConnection .

Please use the variadic overload of this function

Invokes this method on a Q_GADGET 。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.

警告： In addition to the limitations of the variadic invoke () overload, the arguments must have the same type as the ones expected by the method, else, the behavior is undefined.
