MFXFilterComboBox, Chinese characters can't be input

[Hamster5295]

Before i start, i have to say that I LOVE the outstanding features very much! 😸

However, i've found it unable to text Chinese characters into the Search field of MFXFilterComboBox. I'm not familiar with character encodings so i can't figure out which part went wrong
It's a critical problem since i'm using it to create a Chinese font selector, where users will have to search through a bunch of fonts

Hope there will be a fix soon 🍀

By the way, There's no Chinese translation in the repo currently. If i want to contribute, what should I do? 🤔

It's found that you CAN input these characters by copying and pasting them into the search box, but you CAN'T do it by typing with an input method (e.g. MSPY)

I looked into this Issue and it's an issue on MFXTextField. When it's placed in a Popup (javafx.stagePopup or MFXPopup), you can't use an input method on it.

I'm a novice user of MaterialFX, still looking at the demo, haven't started using it yet. I'll take some time to keep track of the issue, but it won't necessarily fix it.

After investigation, I found out that it is not MaterialFX causing the problem.

This is an issue on OpenJFX. When there is a TextField in the window, another TextField in the Popup that pops up on this window cannot be focused by the IME, and all input by the IME will appear in the TextField thar in the main window.

I will try to report the issue to OpenJFX.

Here is a short reproducer.

It's a window that contains TextField, and will pop up another TextField on the top left of the screen.

When you use the input method to input the upper left of the screen TextField, you will find that your input actually goes to the TextField in the main form.

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TextField;
import javafx.scene.layout.VBox;
import javafx.stage.Popup;
import javafx.stage.Stage;

public class JFXTest extends Application {
    @Override
    public void start(Stage primaryStage) throws Exception {
        var root = new VBox(new TextField());
        primaryStage.setScene(new Scene(root, 100, 100));
        primaryStage.show();

        Popup popup = new Popup();
        popup.getContent().add(new TextField());
        popup.show(primaryStage, 0.0, 0.0);
    }

    public static void main(String[] args) {
        Application.launch(JFXTest.class, args);
    }
}

For non-Asian users, this problem can also be reproduced using the Windows emoji panel (Use the shortcut key Windows logo key + .(period) to open).

That's of great help. Thank you! 😉

I'll try ro reproduce the issue and study a workaround if possible

Can't promise anything though. Sorry guys, it's been so tough lately, the university, MaterialFX a secret project for the JavaFX community that is talking a a lot of time, I'll do my best

Thank you for your great work.

This is caused by an OpenJFX issue, which I've reported on the mailing list, and I think it should probably be resolved by someone at Oracle or Gluon.

The issue has been reported to Oracle and tracked by JBS, see JDK-8284583.
