Input Method Editor (IME) not working #25

Open PlusLake opened 2 months ago

PlusLake commented 2 months ago

I found that IME (input method editor) is not working. So that user in Japan / Taiwan / Korea / China may have difficulty to input. (Copy & paste is a temporary workaround)

I have tried JTextArea and JTextField and I believe others cannot work too.

At the end of the video, I clicked "Restart" on the Fcitx menu and the application crashed entirely. (I am not sure it is related or not)

Version Info

Minimal reproducible example

import javax.swing.*;
import java.awt.*;

public class Example {
    public static void main(String[] args) {
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add(new JTextArea());
        frame.setSize(new Dimension(300, 200));
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }
}

(Appreciate for the great work on AWT! Love to see my application rendered extremelly smooth)

It has been verified that fcitx-Chinese input method is also unable to input. Restarting fcitx will cause the program to crash. However, when I execute 

java -agentlib:native-image-agent=config-output-dir=config -Djdk.gtk.version=2 -jar lessions.jar

and restart the fcitx input method framework, it does not crash. 

native-image --no-fallback -H:+AddAllCharsets -H:ConfigurationFileDirectories=config --enable-url-protocols=https,http -Djava.awt.headless=false  --allow-incomplete-classpath -J-Xmx16G -Djdk.gtk.version=2 -jar lessions.jar
./lession

Then executing the program generated by native-image will not crash too.

export GRAALVM_HOME=/home/mxh/software/graalvm-jdk-21.0.3+7.1 export JAVA_HOME=/home/mxh/software/graalvm-jdk-21.0.3+7.1 export PATH=$JAVA_HOME/bin:$PATH export GRAALVM_HOME

Operating System: UOS Desktop 20 Professional Kernel: Linux 6.1.32-amd64-desktop-hwe Architecture: x86-64 fcitx: 1:4.2.9.32.46-1

And it seems like there should be two bugs. one is that JTextField cannot recognize Chinese IME; and the other bug is that fcitx restarts and the program crashes.(This issue can be resolved by modifying the steps.)

I also have an idea that has not been completed for verification, popping up a swing program through javafx, I wonder if this swing program can accept Chinese input? Gluon-maven-plugin does not seem to support exporting javafx+swing program.
