有没有办法在JOptionPane showInputDialog中只有OK按钮（而且没有CANCEL按钮）？ [英] Is there a way to only have the OK button in a JOptionPane showInputDialog (and no CANCEL button)?

问题描述

我已经看到这可以在其他类型的对话框窗口中使用，例如showConfirmDialog，其中可以指定按钮的数量及其名称;但使用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。

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.

推荐答案

只需将自定义JPanel添加为 JOptionPane.showOptionDialog（）：

Just add a custom JPanel as a message to 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();
    // ...
}
