QGraphicsScene subclass representing the model designer.

%Docstring
Constructor for QgsModelGraphicsScene with the specified ``parent`` object.

%Docstring
Sets the combination of ``flags`` controlling how the scene is rendered and behaves.

.. seealso:: :py:func:`flags`
%End

    void setFlag( QgsModelGraphicsScene::Flag flag, bool on = true );
%Docstring
Enables or disables a particular ``flag`` for the scene. Other existing
flags are not affected.

.. seealso:: :py:func:`setFlags`

.. seealso:: :py:func:`flags`
%End

    QgsModelGraphicsScene::Flags flags() const;
%Docstring
Returns the current combination of flags set for the scene.

    void createItems( QgsProcessingModelAlgorithm *model, QgsProcessingContext &context );
%Docstring
Populates the scene by creating items representing the specified ``model``.
%End

    QList<QgsModelComponentGraphicItem *> selectedComponentItems();
%Docstring
Returns list of selected component items.
%End

    QgsModelComponentGraphicItem *componentItemAt( QPointF position ) const;
%Docstring
Returns the topmost component item at a specified ``position``.
%End

    void deselectAll();
%Docstring
Clears any selected items in the scene.

Call this method rather than QGraphicsScene.clearSelection, as the latter does
not correctly emit signals to allow the scene's model to update.
%End

    void setSelectedItem( QgsModelComponentGraphicItem *item );
%Docstring
Clears any selected items and sets ``item`` as the current selection.
%End

  signals:

    void rebuildRequired();
%Docstring
Emitted when a change in the model requires a full rebuild of the scene.
%End

    void componentAboutToChange( const QString &text, int id = 0 );
%Docstring
Emitted whenever a component of the model is about to be changed.

The ``text`` argument gives the translated text describing the change about to occur, and the
optional ``id`` can be used to group the associated undo commands.
%End

    void componentChanged();
%Docstring
Emitted whenever a component of the model is changed.
%End

    void selectedItemChanged( QgsModelComponentGraphicItem *selected );
%Docstring
Emitted whenever the selected item changes.
If ``None``, no item is selected.

%Docstring
Creates a new graphic item for a model parameter.

%Docstring
Creates a new graphic item for a model child algorithm.

Creates a new graphic item for a model output.
