Connector

This article demonstrates how to connect shapes with connectors and change their targets using Aspose.Slides for C++.

Add a Connector

Insert a connector shape between two points on the slide.

static void AddConnector()
{
    auto presentation = MakeObject<Presentation>();
    auto slide = presentation->get_Slide(0);

    auto connector = slide->get_Shapes()->AddConnector(ShapeType::BentConnector2, 0, 0, 100, 100);
    presentation->Dispose();
}

Access a Connector

Retrieve the first connector shape added to a slide.

static void AccessConnector()
{
    auto presentation = MakeObject<Presentation>();
    auto slide = presentation->get_Slide(0);

    slide->get_Shapes()->AddConnector(ShapeType::BentConnector2, 0, 0, 100, 100);

    // Access the first connector on the slide.
    auto connector = SharedPtr<IConnector>();
    for (auto&& shape :  slide->get_Shapes())
    {
        if (ObjectExt::Is<IConnector>(shape))
        {
            connector = ExplicitCast<IConnector>(shape);
            break;
        }
    }

    presentation->Dispose();
}

Remove a Connector

Delete a connector from the slide.

static void RemoveConnector()
{
    auto presentation = MakeObject<Presentation>();
    auto slide = presentation->get_Slide(0);

    auto connector = slide->get_Shapes()->AddConnector(ShapeType::BentConnector2, 0, 0, 100, 100);

    slide->get_Shapes()->Remove(connector);

    presentation->Dispose();
}

Reconnect Shapes

Attach a connector to two shapes by assigning start and end targets.

static void ReconnectShapes()
{
    auto presentation = MakeObject<Presentation>();
    auto slide = presentation->get_Slide(0);

    auto shape1 = slide->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 0, 0, 50, 50);
    auto shape2 = slide->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 100, 100, 50, 50);
    auto connector = slide->get_Shapes()->AddConnector(ShapeType::BentConnector2, 0, 0, 100, 100);

    connector->set_StartShapeConnectedTo(shape1);
    connector->set_EndShapeConnectedTo(shape2);

    presentation->Dispose();
}
