GridLayout面板上的面板

Question

是否可以在一个具有GridLayout图像的面板上显示一个面板(例如Panel，它几乎是透明的)？

JPanel mainPanel = new JPanel(new BorderLayout());

JPanel gridOfImages = new JPanel(new GridLayout(3,3));//Panel with a grid of images
JPanel nearlyOpaquePanel = new JPanel(); //A panel that is almost transparent.

// assuming that all already have the required properties like size and colour.

mainPanel.add(gridOfImages,Borderlayout.CENTER);
mainPanel.add(nearlyOpaquePanel,BorderLayout.CENTER);

我的想法是，面板将堆叠在一起，gridOfImages将通过nearlyOpaquePanel显示，但我的结果是，我只有nearlyOpaquePanel显示，我无法通过它看到gridOfImages。
