%Docstring
 A button for creating and modifying QgsSymbol settings.

 The button shows a preview icon for the current symbol, and will open a detailed symbol editor dialog (or
 panel widget) when clicked.

  public:

    QgsSymbolButton( QWidget *parent /TransferThis/ = 0, const QString &dialogTitle = QString() );
%Docstring
 Construct a new symbol button.
 Use ``dialogTitle`` string to define the title to show in the symbol settings dialog.

    virtual QSize sizeHint() const;

    void setSymbolType( QgsSymbol::SymbolType type );
%Docstring
 Sets the symbol ``type`` which the button requires.
 If the type differs from the current symbol type, the symbol will be reset
 to a default symbol style of the new type.
.. seealso:: symbolType()

%Docstring
 Returns the symbol type which the button requires.

 Returns the layer associated with the widget.
.. seealso:: setLayer()
 :rtype: QgsVectorLayer
%End

    void setLayer( QgsVectorLayer *layer );
%Docstring
 Sets a ``layer`` to associate with the widget. This allows the
 widget to setup layer related settings within the symbol settings dialog,
 such as correctly populating data defined override buttons.
.. seealso:: layer()
%End

    void registerExpressionContextGenerator( QgsExpressionContextGenerator *generator );
%Docstring
 Register an expression context generator class that will be used to retrieve
 an expression context for the button when required.
%End

  public slots:
