提问by Jame
I am developing a small desktop application in Netbeans. on my UI i have a JTabbedPanehaving 3 tabs in it now i come across a situation where i need to temporarily disable 2nd and 3rd tab. How could i do that programatically. Rightnow i am using the following code but its not working:
我正在 Netbeans 中开发一个小型桌面应用程序。在我的用户界面上，我有JTabbedPane3 个选项卡，现在我遇到了需要暂时禁用第二个和第三个选项卡的情况。我怎么能以编程方式做到这一点。现在我正在使用以下代码，但它不起作用：
int n = jTabbedPane1.indexOfTab("Second Tab Name");// This line returns one as expected
jTabbedPane1.getTabComponentAt(n).enable(false);// but i guess some un-expected thing happens here

I believe what you are looking for is this.
我相信你正在寻找的是这个。
jTabbedPane1.setEnabledAt(n, false);
回答by Miki Maine Amdu
you can simply use
你可以简单地使用
tabObject.setEnabledAt(index, enabled);
tabObject :- is the JTabbedPane index would start from 0.So,you Should use 1 and 2 for the second and third tabs enabled is the Boolean value true for on and false for off. i think it helps
tabObject :- 是 JTabbedPane 索引将从 0 开始。所以，你应该为第二个和第三个选项卡使用 1 和 2 启用是布尔值 true 表示开，false 表示关闭。我认为它有帮助
