连接器

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

添加连接器

在幻灯片的两个点之间插入一个连接线形状。

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();
    }
}

访问连接器

检索添加到幻灯片的第一个连接线形状。

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

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

        // 访问幻灯片上的第一个连接器。
        IConnector connector = null;
        for (IShape shape : slide.getShapes()) {
            if (shape instanceof IConnector) {
                connector = (IConnector) shape;
                break;
            }
        }
    } finally {
        presentation.dispose();
    }
}

移除连接器

从幻灯片中删除连接线。

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上。

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();
    }
}
