evaluateBindings()

void QPropertyObserverPointer::evaluateBindings	(	PendingBindingObserverList &	bindingObservers,

nextObserver()

QPropertyObserverPointer QPropertyObserverPointer::nextObserver ( ) const

Referenced by QPropertyBindingDataPointer::observerCount().

Here is the caller graph for this function:

binding

)

Definition at line 837 of file qproperty.cpp.

notify()

void QPropertyObserverPointer::notify ( QUntypedPropertyData * propertyDataPtr )

inline

Walks through the list of property observers, and calls any ChangeHandler found there. It doesn't do anything with bindings, which are only handled in QPropertyBindingPrivate::evaluateRecursive.

Definition at line 883 of file qproperty_p.h.

References QPropertyObserverNodeProtector::next(), and ptr.

Here is the call graph for this function:

observeProperty()

References ptr, and unlink().

Here is the call graph for this function:

operator bool()

QPropertyObserverPointer::operator bool ( ) const

inlineexplicit

Definition at line 168 of file qproperty_p.h.

References ptr.

setBindingToNotify()

void QPropertyObserverPointer::setBindingToNotify ( QPropertyBindingPrivate * binding )

inline

Definition at line 147 of file qproperty_p.h.

References ptr.

setBindingToNotify_unsafe()

void QPropertyObserverPointer::setBindingToNotify_unsafe

(

QPropertyBindingPrivate *

binding

)

The same as setBindingToNotify, but assumes that the tag is already correct.

Definition at line 817 of file qproperty.cpp.

setChangeHandler()

void QPropertyObserverPointer::setChangeHandler

(

QPropertyObserver::ChangeHandler

changeHandler

)

Definition at line 806 of file qproperty.cpp.

References ptr.

unlink()

void QPropertyObserverPointer::unlink ( )

inline

Unlinks

Definition at line 126 of file qproperty_p.h.

Referenced by observeProperty().

Here is the caller graph for this function:

unlink_fast()

void QPropertyObserverPointer::unlink_fast ( )

inline

Like unlink, but does not handle ObserverIsAlias. Must only be called in places where we know that we are not dealing with such an observer.

Definition at line 137 of file qproperty_p.h.

Referenced by QPropertyObserverNodeProtector::~QPropertyObserverNodeProtector().
