連接線

本文示範如何使用 Aspose.Slides for Android via Java 連接形狀與連接線，並更改它們的目標。

新增連接線

在投影片的兩個點之間插入一條連接線形狀。

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

        IConnector connector = slide.getShapes().addConnector(ShapeType.BentConnector2, 0, 0, 100, 100);
    } finally {
        presentation.dispose();
    }
}

存取連接線

取得已新增至投影片的第一個連接線形狀。

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

        slide.getShapes().addConnector(ShapeType.BentConnector2, 0, 0, 100, 100);

        // 存取投影片上的第一個連接線。
        IConnector connector = null;
        for (IShape shape : slide.getShapes()) {
            if (shape instanceof IConnector) {
                connector = (IConnector) shape;
                break;
            }
        }
    } finally {
        presentation.dispose();
    }
}

移除連接線

從投影片中刪除連接線。

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

        IConnector connector = slide.getShapes().addConnector(ShapeType.BentConnector2, 0, 0, 100, 100);

        slide.getShapes().remove(connector);
    } finally {
        presentation.dispose();
    }
}

重新連接形狀

透過指派起始與結束目標，將連接線附加到兩個形狀。

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

        IAutoShape shape1 = slide.getShapes().addAutoShape(ShapeType.Rectangle, 0, 0, 50, 50);
        IAutoShape shape2 = slide.getShapes().addAutoShape(ShapeType.Rectangle, 100, 100, 50, 50);
        IConnector connector = slide.getShapes().addConnector(ShapeType.BentConnector2, 0, 0, 100, 100);

        connector.setStartShapeConnectedTo(shape1);
        connector.setEndShapeConnectedTo(shape2);
    } finally {
        presentation.dispose();
    }
}
