Disable enable JButton in Java
提问by 3D-kreativ
I have a problem I'm trying to disable JButton with setEnabled(false) like this:
我有一个问题，我正在尝试使用 setEnabled(false) 禁用 JButton，如下所示：
ButtonNewCustomer.setEnabled(false);
But this didn't work so then I imported the Applet packages, but still not working, then I discovered that I also needed to use extends Applet in the class, but the problem is that I'm already using extends for other things like this:
但这不起作用，所以我导入了 Applet 包，但仍然无法正常工作，然后我发现我还需要在类中使用 extends Applet，但问题是我已经将扩展用于其他类似的东西：
public class GUI4EX extends JFrame implements ActionListener {
...
}
I have tried to add Applet, but this dont't work! Is there a way to solve this? Thanks!
我曾尝试添加 Applet，但这不起作用！有没有办法解决这个问题？谢谢！
EDIT: It's working know! The problem was a misspelling of the buttonNewCustomer. The first letter 'b' was 'B'. Sorry! And thanks for the help!
编辑：它的工作知道！问题是 buttonNewCustomer 的拼写错误。第一个字母“b”是“B”。对不起！并感谢您的帮助！

Make sure that you are disabling/enabling your button before setting the frame's visibility.
确保在设置框架的可见性之前禁用/启用按钮。
