Detailed description

[static] QLibrary_LoadHint ExportExternalSymbolsHint

Description: Enum constant QLibrary::ExportExternalSymbolsHint

[static] QLibrary_LoadHint LoadArchiveMemberHint

Description: Enum constant QLibrary::LoadArchiveMemberHint

[static] QLibrary_LoadHint ResolveAllSymbolsHint

Description: Enum constant QLibrary::ResolveAllSymbolsHint

[virtual] void childEvent(QChildEvent ptr arg1)

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

This method can be reimplemented in a derived class.

[const] string errorString

Description: Method QString QLibrary::errorString()

[virtual] bool event(QEvent ptr arg1)

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

This method can be reimplemented in a derived class.

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

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

This method can be reimplemented in a derived class.

[const] string fileName

Description: Method QString QLibrary::fileName()

void fileName=(string fileName)

[const] bool isLoaded

Description: Method bool QLibrary::isLoaded()

[const] bool isLoaded?

Description: Method bool QLibrary::isLoaded()

[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.
