我想制作一个分割窗格，在左侧显示一个图像列表，一旦您点击这些图像，它应该在右侧显示更大尺寸的图像。我想知道是否有人知道如何做到这一点，因为我似乎无法在拆分窗格的左侧创建图像列表（图像图标）。我可以阅读并打开.dcm图像（使用ImageJ），它们显示在内部框架中，但我不能使它在分割窗格中工作。如果有人对如何使这项工作有一个通用的解决方案，那将非常有帮助。提前致谢。
所以这是我的代码，在左侧显示问题列表，然后在拆分窗格的右侧显示有关它的更多信息。我想知道如何将左侧的图像图标列表。因此，如果单击图像，它将显示在右侧。

//Create the list of images and put it in a scroll pane.
list = new JGridPanel(1, imageNames.length);
JScrollPane pictureScrollPane = new JScrollPane(picture);
for (int i=0; i < imageNames.length; i++) {
picture = new JButton();
picture.setBackground(Color.black);
ImageIcon img = createImageIcon("images/" + "#FileName" + ".gif");
picture.setIcon(img);
list.setComponent(picture, 0, i);
}
//Create a split pane with the two scroll panes in it.
splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT,
list, pictureScrollPane);
splitPane.setOneTouchExpandable(true);
splitPane.setDividerLocation(150);
//Provide minimum sizes for the two components in the split pane.
Dimension minimumSize = new Dimension(100, 50);
list.setMinimumSize(minimumSize);
pictureScrollPane.setMinimumSize(minimumSize);

并使用this class作为JGridPanel。
