class QgsLayout : QGraphicsScene, QgsExpressionContextGenerator, QgsLayoutUndoObjectInterface
{
%Docstring
 Base class for layouts, which can contain items such as maps, labels, scalebars, etc.
.. versionadded:: 3.0
%End

%TypeHeaderCode
#include "qgslayout.h"
%End
  public:

    enum ZValues
    {
      ZPage,

      ZMapTool,
      ZSnapIndicator,
    };

    QgsLayout( QgsProject *project );
%Docstring
 Construct a new layout linked to the specified ``project``.

 If the layout is a "new" layout (as opposed to a layout which will
 restore a previous state from XML) then initializeDefaults() should be
 called on the new layout.
%End

    ~QgsLayout();

    void initializeDefaults();
%Docstring
 Initializes an empty layout, e.g. by adding a default page to the layout. This should be called after creating
 a new layout.
%End

    QgsProject *project() const;
%Docstring
 The project associated with the layout. Used to get access to layers, map themes,
 relations and various other bits. It is never null.
 :rtype: QgsProject
%End

    QgsLayoutModel *itemsModel();
%Docstring
 Returns the items model attached to the layout.
 :rtype: QgsLayoutModel

    QList<QgsLayoutItem *> selectedLayoutItems( const bool includeLockedItems = true );
%Docstring
 Returns list of selected layout items.

 If ``includeLockedItems`` is set to true, then locked items will also be included
 in the returned list.
 :rtype: list of QgsLayoutItem
%End

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

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

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

    bool raiseItem( QgsLayoutItem *item, bool deferUpdate = false );
%Docstring
 Raises an ``item`` up the z-order.
 Returns true if the item was successfully raised.

 If ``deferUpdate`` is true, the scene will not be visibly updated
 to reflect the new stacking order. This allows multiple
 raiseItem() calls to be made in sequence without the cost of
 updating the scene for each one.

.. seealso:: updateZValues()
 :rtype: bool
%End

    bool lowerItem( QgsLayoutItem *item, bool deferUpdate = false );
%Docstring
 Lowers an ``item`` down the z-order.
 Returns true if the item was successfully lowered.

 to reflect the new stacking order. This allows multiple
 raiseItem() calls to be made in sequence without the cost of
 updating the scene for each one.

%Docstring
 Raises an ``item`` up to the top of the z-order.
 Returns true if the item was successfully raised.

%End

    void updateZValues( const bool addUndoCommands = true );
%Docstring

 z order list. This should be called after any stacking changes
 which deferred z-order updates.
