Aspose::Words::DocumentVisitor::VisitShapeEnd method

DocumentVisitor::VisitShapeEnd method

Called when enumeration of a shape has ended.

virtual Aspose::Words::VisitorAction Aspose::Words::DocumentVisitor::VisitShapeEnd(System::SharedPtr<Aspose::Words::Drawing::Shape> shape)

Parameter	Type	Description
shape	System::SharedPtr<Aspose::Words::Drawing::Shape>	The object that is being visited.

ReturnValue

A VisitorAction value that specifies how to continue the enumeration.

Examples

Shows how to create a group of shapes, and print its contents using a document visitor.
