Detailed description

EditNextItem

Signature: [static,const] QAbstractItemDelegate_EndEditHint EditNextItem

Description: Enum constant QAbstractItemDelegate::EditNextItem

Python specific notes:
The object exposes a readable attribute 'EditNextItem'. This is the getter.

EditPreviousItem

Signature: [static,const] QAbstractItemDelegate_EndEditHint EditPreviousItem

Description: Enum constant QAbstractItemDelegate::EditPreviousItem

Python specific notes:
The object exposes a readable attribute 'EditPreviousItem'. This is the getter.

NoHint

Signature: [static,const] QAbstractItemDelegate_EndEditHint NoHint

Description: Enum constant QAbstractItemDelegate::NoHint

Python specific notes:
The object exposes a readable attribute 'NoHint'. This is the getter.

RevertModelCache

Signature: [static,const] QAbstractItemDelegate_EndEditHint RevertModelCache

Description: Enum constant QAbstractItemDelegate::RevertModelCache

Python specific notes:
The object exposes a readable attribute 'RevertModelCache'. This is the getter.

SubmitModelCache

Signature: [static,const] QAbstractItemDelegate_EndEditHint SubmitModelCache

Description: Enum constant QAbstractItemDelegate::SubmitModelCache

Python specific notes:
The object exposes a readable attribute 'SubmitModelCache'. This is the getter.

_const_cast

Signature: [const] QAbstractItemDelegate ptr _const_cast

Description: Returns a non-const reference to self.

Basically, this method allows turning a const object reference to a non-const one. This method is provided as last resort to remove the constness from an object. Usually there is a good reason for a const object reference, so using this method may have undesired side effects.

This method has been introduced in version 0.29.6.

_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.
