我只是尝试在面板上添加带有5个标签的标签式窗格,但只显示最终标签(标签e )。
我显然在这里做了一些根本性的错误,我尝试更改Panel的布局管理器,标签窗格正在添加,但我不认为这是问题所在。任何adivce都会有所帮助,谢谢!
主类代码:
public static void main(String[] args) {
JFrame frame = new JFrame("Data Structures Program");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(600, 600);
GraphicPanel G = new GraphicPanel();
frame.add(G.getPanel());
frame.setVisible(true);
}
图形类
public class GraphicPanel {
public JPanel topPanel;
public GraphicPanel() {
JPanel Panel = new JPanel();
Panel.setLayout(new GridLayout(1, 1));
JTabbedPane tabbedPane = new JTabbedPane();
tabbedPane.addTab("a", Panel);
tabbedPane.addTab("b", Panel);
tabbedPane.addTab("c", Panel);
tabbedPane.addTab("d", Panel );
tabbedPane.addTab("e", Panel );
topPanel = new JPanel();
topPanel.setLayout(new GridLayout(1, 1));
topPanel.add(tabbedPane);
}
public JPanel getPanel(){
return topPanel;
}
}
答案 0 :(得分:5)
如果要在JPanel
JTabbedPane
的新实例
试试这段代码:
JTabbedPane tabbedPane = new JTabbedPane();
tabbedPane.addTab("a", new Panel());
tabbedPane.addTab("b", new Panel());
tabbedPane.addTab("c", new Panel());
tabbedPane.addTab("d", new Panel());
tabbedPane.addTab("e", new Panel());
