Is there a way to only have the OK button in a JOptionPane showInputDialog (and no CANCEL button)?
提问by Coffee_Table
I've seen that this is possible in other types of dialog windows such as "showConfirmDialog", where one can specify the amount of buttons and their names; but is this same functionality achievable when using "showInputDialog"? I couldn't seem to find this type of thing in the API. Perhaps I just missed it, but any help is appreciated.
我已经看到这在其他类型的对话框窗口中是可能的，例如“showConfirmDialog”，其中可以指定按钮的数量及其名称；但是在使用“showInputDialog”时是否可以实现相同的功能？我似乎无法在 API 中找到这种类型的东西。也许我只是错过了它，但感谢任何帮助。

Just add a custom JPanel as a message to JOptionPane.showOptionDialog():
只需添加一个自定义 JPanel 作为消息到JOptionPane.showOptionDialog()：
String[] options = {"OK"};
JPanel panel = new JPanel();
JLabel lbl = new JLabel("Enter Your name: ");
JTextField txt = new JTextField(10);
panel.add(lbl);
panel.add(txt);
int selectedOption = JOptionPane.showOptionDialog(null, panel, "The Title", JOptionPane.NO_OPTION, JOptionPane.QUESTION_MESSAGE, null, options , options[0]);
if(selectedOption == 0)
{
String text = txt.getText();
// ...
}

JOptionPane.showInputDialog()returns the string the user has entered if the user clicks "OK" and returns nullotherwise. See this:
JOptionPane.showInputDialog()如果用户单击“确定”，则返回用户输入的字符串，null否则返回。看到这个：
Returns: user's input, or null meaning the user canceled the input
返回： 用户的输入，或 null 表示用户取消输入
You can't do this using showInputDialog()
你不能这样做 showInputDialog()
However, you can use JOptionPane#showOptionDialog():
但是，您可以使用JOptionPane#showOptionDialog()：
Object[] buttons = {"OK"};
int res = JOptionPane.showOptionDialog(yourFrame,
"YourMessage","YourTitle",
JOptionPane....,
JOptionPane..., null, buttons , buttons[0]);
As @HovercraftFullOfEels stated on the comments, you can add JTextFieldto the dialog and achieve this.
正如@HovercraftFullOfEels 在评论中所述，您可以添加JTextField到对话框中并实现此目的。
