Constructor for QgsLayoutContext.

Sets the combination of ``flags`` that will be used for rendering the layout.

Enables or disables a particular rendering ``flag`` for the layout. Other existing
flags are not affected.

Check whether a particular rendering ``flag`` is enabled for the layout.

%End

    QgsRenderContext::Flags renderContextFlags() const;
%Docstring
Returns the combination of render context flags matched to the layout context's settings.
%End

    void setFeature( const QgsFeature &feature );
%Docstring
Sets the current ``feature`` for evaluating the layout. This feature may
be used for altering an item's content and appearance for a report
or atlas layout.

Emits the changed() signal.

.. seealso:: :py:func:`feature()`
%End

    QgsFeature feature() const;
%Docstring
Returns the current feature for evaluating the layout. This feature may
be used for altering an item's content and appearance for a report
or atlas layout.

%Docstring
Returns the vector layer associated with the layout's context.

.. seealso:: :py:func:`setLayer()`
%End

    void setLayer( QgsVectorLayer *layer );
%Docstring
Sets the vector ``layer`` associated with the layout's context.

Emits the changed() signal.

.. seealso:: :py:func:`layer()`
%End

    void setDpi( double dpi );
%Docstring
Sets the ``dpi`` for outputting the layout. This also sets the
corresponding DPI for the context's measurementConverter().

.. seealso:: :py:func:`dpi()`
%End

    double dpi() const;
%Docstring
Returns the ``dpi`` for outputting the layout.

.. seealso:: :py:func:`setDpi()`

    QgsLayoutMeasurementConverter &measurementConverter();
%Docstring
Returns the layout measurement converter to be used in the layout. This converter is used
for translating between other measurement units and the layout's native unit.
%End

    bool isPreviewRender() const;
%Docstring
Returns true if the render current being conducted is a preview render,
i.e. it is being rendered inside a QGraphicsView widget as opposed to a destination
device (such as an image).
%End

    bool gridVisible() const;
%Docstring
Returns true if the page grid should be drawn.

.. seealso:: :py:func:`setGridVisible()`
%End

    void setGridVisible( bool visible );
%Docstring
Sets whether the page grid should be ``visible``.

.. seealso:: :py:func:`gridVisible()`

%Docstring
Returns true if the item bounding boxes should be drawn.

.. seealso:: :py:func:`setBoundingBoxesVisible()`

    void setBoundingBoxesVisible( bool visible );
%Docstring
Sets whether the item bounding boxes should be ``visible``.

.. seealso:: :py:func:`boundingBoxesVisible()`
%End

    void setPagesVisible( bool visible );
%Docstring
Sets whether the page items should be ``visible`` in the layout. Removing
them will prevent both display of the page boundaries in layout views and
will also prevent them from being rendered in layout exports.

.. seealso:: :py:func:`pagesVisible()`
%End

    bool pagesVisible() const;
%Docstring
Returns whether the page items are be visible in the layout. This setting
effects both display of the page boundaries in layout views and
whether they will be rendered in layout exports.

.. seealso:: :py:func:`setPagesVisible()`
%End

    void setCurrentExportLayer( int layer = -1 );
%Docstring
Sets the current item ``layer`` to draw while exporting. QgsLayoutItem subclasses
which support multi-layer SVG exports must check the currentExportLayer()
and customise their rendering based on the layer.

If ``layer`` is -1, all item layers will be rendered.

.. seealso:: :py:func:`currentExportLayer()`
%End

    int currentExportLayer() const;
%Docstring
Returns the current item layer to draw while exporting. QgsLayoutItem subclasses
which support multi-layer SVG exports must check this
and customise their rendering based on the layer.

If ``layer`` is -1, all item layers should be rendered.

.. seealso:: :py:func:`setCurrentExportLayer()`

  signals:

    void flagsChanged( QgsLayoutContext::Flags flags );
%Docstring
Emitted whenever the context's ``flags`` change.

.. seealso:: :py:func:`setFlags()`
%End

    void layerChanged( QgsVectorLayer *layer );
%Docstring
Emitted when the context's ``layer`` is changed.
%End

    void changed();
%Docstring
Emitted certain settings in the context is changed, e.g. by setting a new feature or vector layer
for the context.
%End

    void dpiChanged();
%Docstring
Emitted when the context's DPI is changed.
