Constructors and Destructors

Binding()

QDeclarativeCompiledBindingsPrivate::Binding::Binding ( )

inline

Definition at line 213 of file qdeclarativecompiledbindings.cpp.

                  : enabled(false), updating(0), property(0),
                    scope(0), target(0), parent(0) {}

Functions

destroy()

void QDeclarativeCompiledBindingsPrivate::Binding::destroy ( DestroyMode  mode )

virtual

Destroy the binding.

Use this instead of calling delete.

Bindings are free to implement their own memory management, so the delete operator is not necessarily safe. The default implementation clears the binding, removes it from the object and calls delete.

Reimplemented from QDeclarativeAbstractBinding.

Definition at line 350 of file qdeclarativecompiledbindings.cpp.

{
    if (mode == DisconnectBinding)
        disconnect(QDeclarativeAbstractBinding::DisconnectOne);

    enabled = false;
    removeFromObject();
    clear();
    parent->q_func()->release();
}

disconnect()

void QDeclarativeCompiledBindingsPrivate::Binding::disconnect ( DisconnectMode  disconnectMode )

virtual

Implements QDeclarativeAbstractBinding.

Definition at line 361 of file qdeclarativecompiledbindings.cpp.

}

setEnabled()

void QDeclarativeCompiledBindingsPrivate::Binding::setEnabled ( bool  e, QDeclarativePropertyPrivate::WriteFlags  flags  )

virtual

update()

void QDeclarativeCompiledBindingsPrivate::Binding::update ( QDeclarativePropertyPrivate::WriteFlags  flags )

virtual
