本文演示了如何在形状上使用 **Aspose.Slides for C++** 添加、访问、移除和更新超链接。

## **添加超链接**

创建一个矩形形状，并将超链接指向外部网站。

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

    auto shape = slide->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 50, 50, 150, 50);
    shape->get_TextFrame()->set_Text(u"Aspose");

    auto paragraph = shape->get_TextFrame()->get_Paragraph(0);
    auto textPortion = paragraph->get_Portion(0);
    textPortion->get_PortionFormat()->set_HyperlinkClick(MakeObject<Hyperlink>(u"https://www.aspose.com"));

    presentation->Dispose();
}
```

## **访问超链接**

读取形状文本部分中的超链接信息。

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

    auto shape = slide->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 50, 50, 150, 50);
    shape->get_TextFrame()->set_Text(u"Aspose");

    auto paragraph = shape->get_TextFrame()->get_Paragraph(0);
    auto textPortion = paragraph->get_Portion(0);
    textPortion->get_PortionFormat()->set_HyperlinkClick(MakeObject<Hyperlink>(u"https://www.aspose.com"));

    auto hyperlink = textPortion->get_PortionFormat()->get_HyperlinkClick();

    presentation->Dispose();
}
```

## **移除超链接**

从形状的文本中清除超链接。

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

    auto shape = slide->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 50, 50, 150, 50);
    shape->get_TextFrame()->set_Text(u"Aspose");

    auto paragraph = shape->get_TextFrame()->get_Paragraph(0);
    auto textPortion = paragraph->get_Portion(0);
    textPortion->get_PortionFormat()->set_HyperlinkClick(MakeObject<Hyperlink>(u"https://www.aspose.com"));

    textPortion->get_PortionFormat()->set_HyperlinkClick(nullptr);

    presentation->Dispose();
}
```

## **更新超链接**

更改现有超链接的目标。使用 `HyperlinkManager` 修改已包含超链接的文本，模拟 PowerPoint 安全更新超链接的方式。

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

    auto shape = slide->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 50, 50, 150, 50);
    shape->get_TextFrame()->set_Text(u"Aspose");

    auto paragraph = shape->get_TextFrame()->get_Paragraph(0);
    auto textPortion = paragraph->get_Portion(0);
    textPortion->get_PortionFormat()->set_HyperlinkClick(MakeObject<Hyperlink>(u"https://old.example.com"));

    // 在现有文本中更改超链接应通过
    // HyperlinkManager，而不是直接设置属性。
    // 这模拟了 PowerPoint 安全更新超链接的方式。
    textPortion->get_PortionFormat()->get_HyperlinkManager()->SetExternalHyperlinkClick(u"https://new.example.com");

    presentation->Dispose();
}
```
