create() [2/2]

QObject * QQmlType::create	(	void **	memory,

Like create without arguments, but allocates some extra space after the object.

Parameters

memory	An out-only argument. *memory will point to the start of the additionally allocated memory.
additionalMemory	The amount of extra memory in bytes that shoudld be allocated.

Note

This function is used to allocate the QQmlData next to the object in the QQmlObjectCreator.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
