class QgsAbstractMeshLayerLabeling
{
%Docstring(signature="appended")
Abstract base class - its implementations define different approaches to
the labeling of a mesh layer.

.. versionadded:: 3.36

#include "qgsmeshlayerlabeling.h"
%End
  public:

    QgsAbstractMeshLayerLabeling();
    virtual ~QgsAbstractMeshLayerLabeling();

    virtual QString type() const = 0;
%Docstring
Unique type string of the labeling configuration implementation
%End

    virtual QgsAbstractMeshLayerLabeling *clone() const = 0 /Factory/;
%Docstring
Returns a new copy of the object
%End


    virtual QDomElement save( QDomDocument &doc, const QgsReadWriteContext &context ) const = 0;
%Docstring
Returns labeling configuration as XML element
%End

    virtual QStringList subProviders() const;
%Docstring
Gets list of sub-providers within the layer's labeling.
%End

    virtual QgsPalLayerSettings settings( const QString &providerId = QString() ) const = 0;
%Docstring
Gets associated label settings. In case of multiple sub-providers with
different settings, they are identified by their ID.
%End

    virtual void setSettings( QgsPalLayerSettings *settings /Transfer/, const QString &providerId = QString() ) = 0;
%Docstring
Set pal settings for a specific provider (takes ownership).

:param settings: Pal layer settings
:param providerId: The id of the provider
%End

    virtual bool requiresAdvancedEffects() const = 0;
%Docstring
Returns ``True`` if drawing labels requires advanced effects like
composition modes, which could prevent it being used as an isolated
cached image or exported to a vector format.
%End

    virtual void multiplyOpacity( double opacityFactor );
%Docstring
Multiply opacity by ``opacityFactor``.

This method multiplies the opacity of the labeling elements (text,
shadow, buffer etc.) by ``opacity`` effectively changing the opacity of
the whole labeling elements.
%End


    static QgsAbstractMeshLayerLabeling *create( const QDomElement &element, const QgsReadWriteContext &context ) /Factory/;
%Docstring
Try to create instance of an implementation based on the XML data
%End

    virtual void toSld( QDomNode &parent, const QVariantMap &props ) const;
%Docstring
Writes the SE 1.1 TextSymbolizer element based on the current layer
labeling settings
%End

    virtual bool accept( QgsStyleEntityVisitorInterface *visitor ) const;
%Docstring
Accepts the specified symbology ``visitor``, causing it to visit all
symbols associated with the labeling.

Returns ``True`` if the visitor should continue visiting other objects,
or ``False`` if visiting should be canceled.
%End

    static QgsPalLayerSettings defaultSettingsForLayer( const QgsMeshLayer *layer );
%Docstring
Returns the default layer settings to use for the specified mesh
``layer``.
%End

  private:
    QgsAbstractMeshLayerLabeling( const QgsAbstractMeshLayerLabeling &rhs );
};

class QgsMeshLayerSimpleLabeling : QgsAbstractMeshLayerLabeling
{
%Docstring(signature="appended")
Basic implementation of the labeling interface for mesh layers.

%End

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

    explicit QgsMeshLayerSimpleLabeling( const QgsPalLayerSettings &settings, bool labelFaces = false );
%Docstring
Constructs simple labeling configuration with given initial
``settings``. Labels are placed on mesh vertices unless ``labelFaces``
is ``True``, when they are placed on mesh faces.

Set pal settings (takes ownership).

Create the instance from a DOM element with saved configuration
