Detailed description

[static] QImageIOPlugin_Capability CanRead

Description: Enum constant enum QImageIOPlugin::CanRead

[static] QImageIOPlugin_Capability CanReadIncremental

Description: Enum constant enum QImageIOPlugin::CanReadIncremental

[static] QImageIOPlugin_Capability CanWrite

Description: Enum constant enum QImageIOPlugin::CanWrite

[virtual,const] int capabilities(QIODevice ptr device,string format)

Description: Virtual method QFlags<enum QImageIOPlugin::Capability> QImageIOPlugin::capabilities(QIODevice *device, const QByteArray &format)

This method can be reimplemented in a derived class.

[virtual] void childEvent(QChildEvent ptr arg1)

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

This method can be reimplemented in a derived class.

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.

[virtual] void customEvent(QEvent ptr arg1)

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

This method can be reimplemented in a derived class.

[virtual] bool event(QEvent ptr arg1)

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

This method can be reimplemented in a derived class.

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

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

This method can be reimplemented in a derived class.

[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.

[virtual,const] string[] keys

Description: Virtual method QStringList QImageIOPlugin::keys()

This method can be reimplemented in a derived class.

[static] new QImageIOPlugin new

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

This method creates an object of class QImageIOPlugin.

[static] new QImageIOPlugin new(QObject ptr parent)

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

This method creates an object of class QImageIOPlugin.

[virtual,const] QImageIOHandler ptr qt_create(QIODevice ptr device,string format)

Description: Virtual method QImageIOHandler * QImageIOPlugin::create(QIODevice *device, const QByteArray &format)

This method can be reimplemented in a derived class.

[const] int receivers(string signal)

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

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

[const] QObject ptr sender

Description: Method QObject * QImageIOPlugin::sender()

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

[static] QMetaObject staticMetaObject

Description: Obtains the static MetaObject for this class.

[virtual] void timerEvent(QTimerEvent ptr arg1)

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

This method can be reimplemented in a derived class.

[static] string tr(string s)

Description: Static method QString QImageIOPlugin::tr(const char *s, const char *c)

This method is static and can be called without an instance.

[static] string tr(string s,string c)

Description: Static method QString QImageIOPlugin::tr(const char *s, const char *c)

This method is static and can be called without an instance.

[static] string tr(string s,string c,int n)

Description: Static method QString QImageIOPlugin::tr(const char *s, const char *c, int n)

This method is static and can be called without an instance.

[static] string trUtf8(string s)

Description: Static method QString QImageIOPlugin::trUtf8(const char *s, const char *c)

This method is static and can be called without an instance.

[static] string trUtf8(string s,string c)

Description: Static method QString QImageIOPlugin::trUtf8(const char *s, const char *c)

This method is static and can be called without an instance.

[static] string trUtf8(string s,string c,int n)

Description: Static method QString QImageIOPlugin::trUtf8(const char *s, const char *c, int n)

This method is static and can be called without an instance.
