Compatibility Members for QObject

The following members of class QObjectare part of the Qt compatibility layer. We advise against using them in new code.

Public Functions

QObject * child(const char * objName, const char * inheritsClass = 0, bool recursiveSearch = true) const
const char * className() const
void insertChild(QObject * object)
bool isA(const char * className) const
const char * name() const
const char * name(const char * defaultName) const
void removeChild(QObject * object)
void setName(const char * name)

Protected Functions

bool checkConnectArgs(const char * signal, const QObject * object, const char * method)

Static Protected Members

QByteArray normalizeSignalSlot(const char * signalSlot)

Member Function Documentation

[protected] bool QObject::checkConnectArgs(const char * signal, const QObject * object, const char * method)

Use QMetaObject::checkConnectArgs() instead.

QObject * QObject::child(const char * objName, const char * inheritsClass = 0, bool recursiveSearch = true) const

Searches the children and optionally grandchildren of this object, and returns a child that is called objName that inherits inheritsClass. If inheritsClass is 0 (the default), any class matches.

If recursiveSearch is true (the default), child() performs a depth-first search of the object's children.

If there is no such object, this function returns 0. If there are more than one, the first one found is returned.

const char * QObject::className() const

Use metaObject()->className() instead.

void QObject::insertChild(QObject * object)

Use setParent() instead, i.e., call object->setParent(this).

bool QObject::isA(const char * className) const

Compare className with the object's metaObject()->className() instead.

const char * QObject::name() const

Use objectName() instead.

See also setName().

const char * QObject::name(const char * defaultName) const

Use objectName() instead.

[static protected] QByteArray QObject::normalizeSignalSlot(const char * signalSlot)

Use QMetaObject::normalizedSignature() instead.

void QObject::removeChild(QObject * object)

Use setParent() instead, i.e., call object->setParent(0).

void QObject::setName(const char * name)

Use setObjectName() instead.

See also name().
