超連結

本篇文章示範如何在形狀上添加、存取、移除和更新超連結，使用 Aspose.Slides for Java。

新增超連結

建立一個矩形形狀，並為其設定指向外部網站的超連結。

static void addHyperlink() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IAutoShape shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 150, 50);
        shape.getTextFrame().setText("Aspose");

        IParagraph paragraph = shape.getTextFrame().getParagraphs().get_Item(0);
        IPortion textPortion = paragraph.getPortions().get_Item(0);
        textPortion.getPortionFormat().setHyperlinkClick(new Hyperlink("https://www.aspose.com"));
    } finally {
        presentation.dispose();
    }
}

存取超連結

從形狀的文字部份讀取超連結資訊。

static void accessHyperlink() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IAutoShape shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 150, 50);
        shape.getTextFrame().setText("Aspose");

        IParagraph paragraph = shape.getTextFrame().getParagraphs().get_Item(0);
        IPortion textPortion = paragraph.getPortions().get_Item(0);
        textPortion.getPortionFormat().setHyperlinkClick(new Hyperlink("https://www.aspose.com"));

        IHyperlink hyperlink = textPortion.getPortionFormat().getHyperlinkClick();
    } finally {
        presentation.dispose();
    }
}

移除超連結

清除形狀文字中的超連結。

static void removeHyperlink() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IAutoShape shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 150, 50);
        shape.getTextFrame().setText("Aspose");

        IParagraph paragraph = shape.getTextFrame().getParagraphs().get_Item(0);
        IPortion textPortion = paragraph.getPortions().get_Item(0);
        textPortion.getPortionFormat().setHyperlinkClick(new Hyperlink("https://www.aspose.com"));

        textPortion.getPortionFormat().setHyperlinkClick(null);
    } finally {
        presentation.dispose();
    }
}

更新超連結

變更現有超連結的目標。使用 HyperlinkManager 來修改已包含超連結的文字，這模仿了 PowerPoint 安全更新超連結的方式。

static void updateHyperlink() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IAutoShape shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 150, 50);
        shape.getTextFrame().setText("Aspose");

        IParagraph paragraph = shape.getTextFrame().getParagraphs().get_Item(0);
        IPortion textPortion = paragraph.getPortions().get_Item(0);
        textPortion.getPortionFormat().setHyperlinkClick(new Hyperlink("https://old.example.com"));

        // 在現有文字中變更超連結應透過
        // HyperlinkManager 而不是直接設定屬性。
        // 這模仿了 PowerPoint 安全更新超連結的方式。
        textPortion.getPortionFormat().getHyperlinkManager().setExternalHyperlinkClick("https://new.example.com");
    } finally {
        presentation.dispose();
    }
}
