How to hide tabbed panel in JTabbedPane?
提问by Stephane Grenier
I have:
我有：
JTabbedPane jtabbedPane = new JTabbedPane();
jTabbedPane.addTab("Tab 1", panel1);
jTabbedPane.addTab("Tab 2", panel2);
jTabbedPane.addTab("Tab 3", panel3);
What I want to do is hide Tab 2 when a condition occurs (say the user isn't permitted to access that tabbed panel.
我想要做的是在出现条件时隐藏选项卡 2（例如不允许用户访问该选项卡式面板。
Yes I know you can do:
是的，我知道你可以这样做：
jtabbedPane.setEnabled(1, false); // disable Tab 2
which will gray it out, but I want to completely hide it so that the user doesn't even know it's even a possibility in the software. They shouldn't be even aware that it exists.
这会使它变灰，但我想完全隐藏它，以便用户甚至不知道它在软件中的可能性。他们甚至不应该意识到它的存在。
I do NOT want to do
我不想做
jtabbedPane.remove(1); // remove Tab 2
because I then have to remove/add on a regular basis.
因为我必须定期删除/添加。

The only way is to remove it when you don't want to see it, and re-add it later when you do want it visible.
唯一的方法是在您不想看到它时将其删除，并在您希望它可见时重新添加它。

Solution 3:- You can do something like this, which just doesn't paint the tabArea
解决方案 3：- 你可以做这样的事情，只是不绘制 tabArea
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class Testing {
public void buildGUI() {
JTabbedPane tp = new JTabbedPane();
tp.addTab("A",getPanel("A"));
tp.addTab("B",getPanel("B"));
tp.addTab("C",getPanel("C"));
tp.setUI(new javax.swing.plaf.metal.MetalTabbedPaneUI(){
protected void paintTabArea(Graphics g,int tabPlacement,int selectedIndex){} });
JFrame f = new JFrame();
f.getContentPane().add(tp);
f.pack();
f.setLocationRelativeTo(null);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setVisible(true);
