QProtobufMessagePointer
QProtobufMessage::
constructByName
(const
QString
&
messageType
)
Constructs QProtobufMessage 使用 messageType . Returns a pointer to the constructed QProtobufMessage .
This function attempts to create a message whose type matches
messageType
。若
messageType
is unknown, the function returns
nullptr
. If the message is not found in the registry, the function returns
nullptr
. Ownership of the constructed message is given to the function caller.
Get the value of the property propertyName .
若 propertyName isn't known then the returned QVariant 無效。

false
.
返迴
false
if it failed to store the
value
on the property. Otherwise
true
.
另請參閱 property ().

QProtobufMessagePointer
Synonym for std::unique_ptr< QProtobufMessage , QProtobufMessageDeleter >. Use this to manage the lifetime of dynamically allocated QProtobufMessages, such as those created by calling QProtobufMessage::constructByName .
