连接器

本文演示如何使用 Aspose.Slides for C++ 将形状通过连接线连接并更改其目标。

添加连接线

在幻灯片的两个点之间插入一个连接线形状。

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();
}

访问连接线

检索添加到幻灯片的第一个连接线形状。

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

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

    // 访问幻灯片上的第一个连接器。
    auto connector = SharedPtr<IConnector>();
    for (auto&& shape :  slide->get_Shapes())
    {
        if (ObjectExt::Is<IConnector>(shape))
        {
            connector = ExplicitCast<IConnector>(shape);
            break;
        }
    }

    presentation->Dispose();
}

删除连接线

从幻灯片中删除连接线。

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();
}

重新连接形状

通过分配起始和结束目标，将连接线附加到两个形状。

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();
}
