◆ QUntypedPropertyBinding() [1/6]

QUntypedPropertyBinding::QUntypedPropertyBinding ( )
default

Constructs a null QUntypedPropertyBinding.

◆ QUntypedPropertyBinding() [2/6]

QUntypedPropertyBinding::QUntypedPropertyBinding ( QMetaType metaType,
const BindingFunctionVTable * vtable,
void * function,
