CoreImageHandle	Signature: [static,const] QAbstractVideoBuffer_HandleType CoreImageHandle Description: Enum constant QAbstractVideoBuffer::CoreImageHandle Python specific notes: The object exposes a readable attribute 'CoreImageHandle'. This is the getter.
EGLImageHandle	Signature: [static,const] QAbstractVideoBuffer_HandleType EGLImageHandle Description: Enum constant QAbstractVideoBuffer::EGLImageHandle Python specific notes: The object exposes a readable attribute 'EGLImageHandle'. This is the getter.
GLTextureHandle	Signature: [static,const] QAbstractVideoBuffer_HandleType GLTextureHandle Description: Enum constant QAbstractVideoBuffer::GLTextureHandle Python specific notes: The object exposes a readable attribute 'GLTextureHandle'. This is the getter.
NoHandle	Signature: [static,const] QAbstractVideoBuffer_HandleType NoHandle Description: Enum constant QAbstractVideoBuffer::NoHandle Python specific notes: The object exposes a readable attribute 'NoHandle'. This is the getter.
NotMapped	Signature: [static,const] QAbstractVideoBuffer_MapMode NotMapped Description: Enum constant QAbstractVideoBuffer::NotMapped Python specific notes: The object exposes a readable attribute 'NotMapped'. This is the getter.
QPixmapHandle	Signature: [static,const] QAbstractVideoBuffer_HandleType QPixmapHandle Description: Enum constant QAbstractVideoBuffer::QPixmapHandle Python specific notes: The object exposes a readable attribute 'QPixmapHandle'. This is the getter.
ReadOnly	Signature: [static,const] QAbstractVideoBuffer_MapMode ReadOnly Description: Enum constant QAbstractVideoBuffer::ReadOnly Python specific notes: The object exposes a readable attribute 'ReadOnly'. This is the getter.
ReadWrite	Signature: [static,const] QAbstractVideoBuffer_MapMode ReadWrite Description: Enum constant QAbstractVideoBuffer::ReadWrite Python specific notes: The object exposes a readable attribute 'ReadWrite'. This is the getter.
UserHandle	Signature: [static,const] QAbstractVideoBuffer_HandleType UserHandle Description: Enum constant QAbstractVideoBuffer::UserHandle Python specific notes: The object exposes a readable attribute 'UserHandle'. This is the getter.
WriteOnly	Signature: [static,const] QAbstractVideoBuffer_MapMode WriteOnly Description: Enum constant QAbstractVideoBuffer::WriteOnly Python specific notes: The object exposes a readable attribute 'WriteOnly'. This is the getter.
XvShmImageHandle	Signature: [static,const] QAbstractVideoBuffer_HandleType XvShmImageHandle Description: Enum constant QAbstractVideoBuffer::XvShmImageHandle Python specific notes: The object exposes a readable attribute 'XvShmImageHandle'. This is the getter.
_create	Signature: 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.
_destroy	Signature: void _destroy Description: Explicitly destroys the object Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing.
_destroyed?	Signature: [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.
_is_const_object?	Signature: [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.
_manage	Signature: void _manage Description: Marks the object as managed by the script side. After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required. Usually it's not required to call this method. It has been introduced in version 0.24.
_unmanage	Signature: void _unmanage Description: Marks the object as no longer owned by the script side. Calling this method will make this object no longer owned by the script's memory management. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur. Usually it's not required to call this method. It has been introduced in version 0.24.
create	Signature: void create Description: Ensures the C++ object is created Use of this method is deprecated. Use _create instead 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.
destroy	Signature: void destroy Description: Explicitly destroys the object Use of this method is deprecated. Use _destroy instead Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing.
destroyed?	Signature: [const] bool destroyed? Description: Returns a value indicating whether the object was already destroyed Use of this method is deprecated. Use _destroyed? instead 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.
handle	Signature: [const] variant handle Description: Method QVariant QAbstractVideoBuffer::handle()
handleType	Signature: [const] QAbstractVideoBuffer_HandleType handleType Description: Method QAbstractVideoBuffer::HandleType QAbstractVideoBuffer::handleType()
is_const_object?	Signature: [const] bool is_const_object? Description: Returns a value indicating whether the reference is a const reference Use of this method is deprecated. Use _is_const_object? instead This method returns true, if self is a const reference. In that case, only const methods may be called on self.
mapMode	Signature: [const] QAbstractVideoBuffer_MapMode mapMode Description: Method QAbstractVideoBuffer::MapMode QAbstractVideoBuffer::mapMode()
new	Signature: [static] new QAbstractVideoBuffer ptr new Description: Creates a new object of this class Python specific notes: This method is the default initializer of the object.
release	Signature: void release Description: Method void QAbstractVideoBuffer::release()
unmap	Signature: void unmap Description: Method void QAbstractVideoBuffer::unmap()
