javafx-2 - 在图像中心插入文本

Question

我有这段代码，它将图像插入边框 Pane 的中心:

private static final ImageView iv;    
    static {
        iv = new ImageView(StartPanel.class.getResource("/com/dx57dc/images/6.jpg").toExternalForm());
    }

bpi.setCenter(iv);

现在我遇到了这个问题。我将此插入文本作为图像中心的标签。

Text inftx = new Text("基础设施");

我怎样才能做到这一点？

您可以使用 StackPane执行所需的图像重叠。以下代码可用于您的示例:

private static final ImageView iv;    

static {
    iv = new ImageView(StartPanel.class.getResource("/com/dx57dc/images/6.jpg").toExternalForm());
    Text inftx = new Text("Infrastructure");
    StackPane pane = new StackPane();

    pane.getChildren().add(iv);
    pane.getChildren().add(inftx);

    pane.setAlignment(Pos.CENTER);
}

据了解StackPane tutorial :

The StackPane layout pane places all of the nodes within a single stack with each new node added on top of the previous node. This layout model provides an easy way to overlay text on a shape or image or to overlap common shapes to create a complex shape.
