我正在编写一个自定义主题，它是NimbusLookAndFeel的扩展。 我要重新设计表格的主题一样更改JTable非内容背景颜色
我表主题代码

}
，并延长NimbusLookAndFeel并设置为默认为我的所有组件适用于Java的NimbusBaseUI
import javax.swing.UIManager;
import javax.swing.plaf.nimbus.NimbusLookAndFeel;
public class NimbusBaseUI extends NimbusLookAndFeel {
public NimbusBaseUI() {
super(); // Initialisation and installating
try {
new TableTheme(this);
UIManager.setLookAndFeel(this);
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void initialize() {
// TODO Auto-generated method stub
super.initialize();
}
}
我Mainclass看起来像这样
import java.awt.FlowLayout;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.JTextField;
import javax.swing.UIManager;
class NimbusBaseDemo extends JFrame {
/**
*
*/
private static final long serialVersionUID = 1L;
JTextField jtxt, txtDisEnabled;
int i;
private UIManager.LookAndFeelInfo[] lafs;
public NimbusBaseDemo() {
try {
// Set nimbus look and feel. nimbusBase works only for it.
new NimbusBaseUI();
} catch (Exception e) {
e.printStackTrace();
}
setTitle("Nimbus Base Demo");
setSize(400, 400);
setLayout(new FlowLayout());
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
String columnNames[] = { "Column 1", "Column 2", "Column 3" ,"Column 4"};
String dataValues[][] = { { "12", "234", "67", " " },
{ "-123", "43", "853", "" }, { "93", "89.2", "109",""},
{ "279", "9033", "3092",""} };
JTable table1 = new JTable(dataValues, columnNames);
JScrollPane scrollPane = new JScrollPane(table1);
add(scrollPane);
}
public static void main(String args[]) {
new NimbusBaseDemo();
}
}
最后我得到结果作为
但我不能变化的JTable的研究背景（非内容区域）至白色...
请建议。
这是因为有一个参数使用“内容区”的全部空间。这应该是'table.setFillsViewportHeight（true）;' – AxelH
由于我正在开发唯一的自定义我没有访问表的主题。这是一个完全不同的项目。可以从主题 – Kathi
改变它你能告诉使用你如何使用这个主题，这可能有助于看到的可能性，因为你告诉我们在评论（见我的答案），这是一个Cobol GUI。 – AxelH
