JTable和外观 [英] JTable and Look and Feels

问题描述

改变对象的外观和感觉时，我有一个小问题.在我的应用中，我有

I have small problem with changing look and feel of an object. In my app I have

public class JavaCommander extends JFrame

在这个类中，我有用自己的表模型构造的JTable.一切正常，但是正如我所说，当我想要改变外观时会遇到问题.在菜单栏中，我有一个具有可用外观的菜单.

and in this class I have JTable that is constructed with my own table model. Everything works fine, but as I said there is a problem when I want to change look and feel. In menu bar I have a menu with available look and feels.

menuBar=new JMenuBar();
    JMenu lookMenu=new JMenu("Look and Feel");

    UIManager.LookAndFeelInfo[] info= UIManager.getInstalledLookAndFeels();
    ButtonGroup group=new ButtonGroup();

    for (int i=0;i<info.length;++i)
    {
        JRadioButtonMenuItem but=new JRadioButtonMenuItem(info[i].getClassName());
        but.addActionListener(new ActionListener()
        {

            public void actionPerformed(ActionEvent e) 
            {
                try {
                    UIManager.setLookAndFeel(e.getActionCommand());
                    SwingUtilities.updateComponentTreeUI(JavaCommander.this);
                    table.setShowGrid(true);
                } catch (ClassNotFoundException e1) {
                    e1.printStackTrace();
                } catch (InstantiationException e1) {
                    e1.printStackTrace();
                } catch (IllegalAccessException e1) {
                    e1.printStackTrace();
                } catch (UnsupportedLookAndFeelException e1) {
                    e1.printStackTrace();
                }

            }

        });
        lookMenu.add(but);
        group.add(but);
    }
    menuBar.add(lookMenu);

因此，当我单击其中一个按钮时，应该会更改应用程序的外观.但是当我这样做时，一切都会改变，但是表中元素周围的网格丢失了，所以我需要添加

so when I click on one of the buttons it should change look and feel of my application. But when I do it everything changes but the grid around elements in table is missing so I needed to add

table.setShowGrid(true);

更改外观后，网格丢失是正常现象吗?

is it normal behavior that grid goes missing after changing look and feel?

某些PLAF不会对其进行喷涂.

Some PLAFs do not paint it.

我正要在这个问题中热链接到不同PLAF中表格的一些示例图像.然后，我意识到源代码显示出与您描述的问题相同的问题！

I was just about to hot-link to some example images of tables in different PLAFs, in this question. Then I realized that source shows the same problem as you describe!

我可以在任何PLAF酒吧Nimbus中获得单元格边界/网格线.但是一旦选择了Nimbus，其他任何PLAF都不会再显示单元格边界. :(

I can get cell borders/ grid-lines in any PLAF bar Nimbus. But once Nimbus has been selected, none of the other PLAFs show cell borders any longer. :(
