Detailed description

[const] QUndoStack ptr activeStack

Description: Method QUndoStack * QUndoGroup::activeStack()

void activeStack=(QUndoStack ptr stack)

Description: Method void QUndoGroup::setActiveStack(QUndoStack *stack)

[event] void activeStackChanged(QUndoStack ptr stack)

Description: Signal declaration for QUndoGroup::activeStackChanged(QUndoStack *stack)

You can bind a procedure to this signal.

void addStack(QUndoStack ptr stack)

Description: Method void QUndoGroup::addStack(QUndoStack *stack)

[const] bool canRedo

Description: Method bool QUndoGroup::canRedo()

[event] void canRedoChanged(bool canRedo)

Description: Signal declaration for QUndoGroup::canRedoChanged(bool canRedo)

You can bind a procedure to this signal.

[const] bool canUndo

Description: Method bool QUndoGroup::canUndo()

[event] void canUndoChanged(bool canUndo)

Description: Signal declaration for QUndoGroup::canUndoChanged(bool canUndo)

You can bind a procedure to this signal.

[virtual] void childEvent(QChildEvent ptr arg1)

Description: Virtual method void QUndoGroup::childEvent(QChildEvent *)

This method can be reimplemented in a derived class.

[event] void cleanChanged(bool clean)

Description: Signal declaration for QUndoGroup::cleanChanged(bool clean)

You can bind a procedure to this signal.

void create

Description: Ensures the C++ object is created

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

[const] QAction ptr createRedoAction(QObject ptr parent)

Description: Method QAction * QUndoGroup::createRedoAction(QObject *parent, const QString &prefix)

[const] QAction ptr createRedoAction(QObject ptr parent,string prefix)

Description: Method QAction * QUndoGroup::createRedoAction(QObject *parent, const QString &prefix)

[const] QAction ptr createUndoAction(QObject ptr parent)

Description: Method QAction * QUndoGroup::createUndoAction(QObject *parent, const QString &prefix)

[const] QAction ptr createUndoAction(QObject ptr parent,string prefix)

Description: Method QAction * QUndoGroup::createUndoAction(QObject *parent, const QString &prefix)

[virtual] void customEvent(QEvent ptr arg1)

Description: Virtual method void QUndoGroup::customEvent(QEvent *)

This method can be reimplemented in a derived class.

void destroy

Description: Explicitly destroy the object

Explicitly destroy the object on C++ side if it was owned by the Ruby interpreter. Subsequent access to this object will throw an exception. If the object is not owned by Ruby, this method will do nothing.

[event] void destroyed(QObject ptr arg1)

Description: Signal declaration for QUndoGroup::destroyed(QObject *)

You can bind a procedure to this signal.

[const] bool destroyed?

Description: Returns a value indicating whether the object was already destroyed

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.

[virtual] void disconnectNotify(string signal)

Description: Virtual method void QUndoGroup::disconnectNotify(const char *signal)

This method can be reimplemented in a derived class.

[virtual] bool event(QEvent ptr arg1)

Description: Virtual method bool QUndoGroup::event(QEvent *)

This method can be reimplemented in a derived class.

[virtual] bool eventFilter(QObject ptr arg1,QEvent ptr arg2)

Description: Virtual method bool QUndoGroup::eventFilter(QObject *, QEvent *)

This method can be reimplemented in a derived class.

[event] void indexChanged(int idx)

Description: Signal declaration for QUndoGroup::indexChanged(int idx)

You can bind a procedure to this signal.

[const] bool isClean

Description: Method bool QUndoGroup::isClean()

[const] bool isClean?

Description: Method bool QUndoGroup::isClean()

[const] bool is_const_object?

Description: Returns a value indicating whether the reference is a const reference

This method returns true, if self is a const reference. In that case, only const methods may be called on self.

[static] new QUndoGroup new

Description: Constructor QUndoGroup::QUndoGroup(QObject *parent)

This method creates an object of class QUndoGroup.

[static] new QUndoGroup new(QObject ptr parent)

Description: Constructor QUndoGroup::QUndoGroup(QObject *parent)

This method creates an object of class QUndoGroup.

[const] int receivers(string signal)

Description: Method int QUndoGroup::receivers(const char *signal)

This method is protected and can only be called from inside a derived class.

void redo

Description: Method void QUndoGroup::redo()

[const] string redoText

Description: Method QString QUndoGroup::redoText()

[event] void redoTextChanged(string redoText)

Description: Signal declaration for QUndoGroup::redoTextChanged(const QString &redoText)

You can bind a procedure to this signal.

void removeStack(QUndoStack ptr stack)

Description: Method void QUndoGroup::removeStack(QUndoStack *stack)

[const] QObject ptr sender

Description: Method QObject * QUndoGroup::sender()

This method is protected and can only be called from inside a derived class.

void setActiveStack(QUndoStack ptr stack)

Description: Method void QUndoGroup::setActiveStack(QUndoStack *stack)

[const] QUndoStack ptr[] stacks

Description: Method QList<class QUndoStack *> QUndoGroup::stacks()

[static] QMetaObject staticMetaObject

Description: Obtains the static MetaObject for this class.

[virtual] void timerEvent(QTimerEvent ptr arg1)

Description: Virtual method void QUndoGroup::timerEvent(QTimerEvent *)

This method can be reimplemented in a derived class.
