我有一个Java Swing应用程序,它生成带有文本控件的子对话框.问题是,当您在子对话框中更改键盘布局时,它会在关闭对话框后立即更改.
我需要的是无论是在主框架还是在儿童框架中切换,在切换后都要保持的键盘布局.
这是一个说明问题的SSCCE:
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class InheritInputContext {
public static void main(String[] arg) {
final MainFrame mainFrame = new MainFrame();
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
mainFrame.setPreferredSize(new Dimension(300, 400));
mainFrame.pack();
mainFrame.setLocationRelativeTo(null);
mainFrame.setVisible(true);
}
});
}
}
class MainFrame extends JFrame {
MainFrame() {
setLayout(new BorderLayout());
JTextArea textArea = new JTextArea();
add(textArea, BorderLayout.CENTER);
JButton dialogBtn = new JButton("Dialog");
add(dialogBtn, BorderLayout.SOUTH);
dialogBtn.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
