Simple popup java form with at least two fields
提问by nunos
When the user clicks a button, I want to show a popup form that should have at least two JTextFields and two JLabels, so using JOptionPane.showInputDialogis not a possibility.
当用户单击按钮时，我想显示一个弹出窗体，该窗体应该至少有两个 JTextField 和两个 JLabel，因此JOptionPane.showInputDialog不可能使用。

You should at least consider one of the JOptionPanemethods such as showInputDialog()or showMessageDialog().
您至少应该考虑其中一种JOptionPane方法，例如showInputDialog()或showMessageDialog()。
Addendum: The choice to use JOptionPanehinges more on the suitability of modality, rather than on the number of components shown. See also How to Make Dialogs.
附录：选择使用JOptionPane更多取决于模式的适用性，而不是显示的组件数量。另请参阅如何制作对话框。
Addendum: As noted in a comment by @camickr, you can set the focus to a particular component using the approach discussed in Dialog Focus, cited here.
附录：如@camickr 的评论中所述，您可以使用此处引用的Dialog Focus 中讨论的方法将焦点设置为特定组件。

int result = JOptionPane.showConfirmDialog(null, panel, "Test",
JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE);

System.out.println(combo.getSelectedItem()

} else {
System.out.println("Cancelled");
}
}
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
display();
}
});
}
}

With the small UiBoosterlibrary you can build a form dialog in a few lines of code.
使用小型UiBooster库，您可以用几行代码构建一个表单对话框。
FilledForm form = new UiBooster()
.createForm("Personal informations")
.addText("Whats your first name?")
.addTextArea("Tell me something about you")
.addSelection(
"Whats your favorite movie?",
Arrays.asList("Pulp Fiction", "Bambi", "The Godfather", "Hangover"))
.show();
