VisTextField doesn't stop input processing about vis-ui

[kotcrab]

Does that happen with normal TextField? If so then this is a libGDX issue.

[nikoliazekter]

No, only with VisTextField.

[kotcrab]

Ok then, will take a look.

[kotcrab]

Also, could you post SSCCE, please?

[kotcrab]

I cannot reproduce with this:

public class TestIssue50 {

    public static void main (String[] args) {
        LwjglApplicationConfiguration c = new LwjglApplicationConfiguration();
        c.width = 1280;
        c.height = 720;
        new LwjglApplication(new TestIssue50Application(), c);
    }

}

class TestIssue50Application extends ApplicationAdapter {
    private Stage stage;

    @Override
    public void create () {
        VisUI.load();
        stage = new Stage(new ScreenViewport());
        Table table = new Table();
        table.setFillParent(true);
        table.add(getNewVisTextField()).row();
        table.add(getNewGdxTextField()).row();
        stage.addActor(table);
        Gdx.input.setInputProcessor(new InputMultiplexer(stage, new TestInputProcessor()));
    }

    private VisTextField getNewVisTextField () {
        return new VisTextField("VisTextField");
    }

    private TextField getNewGdxTextField () {
        TextFieldStyle style = new TextFieldStyle(VisUI.getSkin().get(TextFieldStyle.class));
        return new TextField("GdxTextField", style);
    }

    @Override
    public void resize (int width, int height) {
        stage.getViewport().update(width, height, true);
    }

    @Override
    public void render () {
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        stage.act(Gdx.graphics.getDeltaTime());
        stage.draw();
    }

    @Override
    public void dispose () {
        VisUI.dispose();
        stage.dispose();
    }

    class TestInputProcessor extends InputAdapter {

        @Override
        public boolean keyDown (int keycode) {
            System.out.println("PROCESSED, KEYCODE:" + keycode);
            return false;
        }

    }

}

I've just tried to experiment a bit and I found out that I can get the behaviour I described only if VisTextField is an actor inside a Node in a Tree (or VisTree, doesn't matter). libgdx TextField doesn't have this issue in the same conditons though.

Please provide a SSCCE.

public class TestIssue50 {

    public static void main (String[] args) {
        LwjglApplicationConfiguration c = new LwjglApplicationConfiguration();
        c.width = 1280;
        c.height = 720;
        new LwjglApplication(new TestIssue50Application(), c);
    }

}

class TestIssue50Application extends ApplicationAdapter {
    private Stage stage;

    @Override
    public void create () {
        VisUI.load();
        stage = new Stage(new ScreenViewport());
        Table table = new Table();
        table.setFillParent(true);
        VisTree tree = new VisTree();
        table.add(tree);
        tree.add(new Node(getNewVisTextField()));
        tree.add(new Node(getNewGdxTextField()));
        stage.addActor(table);
        Gdx.input.setInputProcessor(new InputMultiplexer(stage, new TestInputProcessor()));
    }

    private VisTextField getNewVisTextField () {
        return new VisTextField("VisTextField");
    }

    private TextField getNewGdxTextField () {
        TextFieldStyle style = new TextFieldStyle(VisUI.getSkin().get(TextFieldStyle.class));
        return new TextField("GdxTextField", style);
    }

    @Override
    public void resize (int width, int height) {
        stage.getViewport().update(width, height, true);
    }

    @Override
    public void render () {
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        stage.act(Gdx.graphics.getDeltaTime());
        stage.draw();
    }

    @Override
    public void dispose () {
        VisUI.dispose();
        stage.dispose();
    }

    class TestInputProcessor extends InputAdapter {

        @Override
        public boolean keyDown (int keycode) {
            System.out.println("PROCESSED, KEYCODE:" + keycode);
            return false;
        }

    }

}

Which VisUI version do you use?

[nikoliazekter]

VisUI 0.9.1 and libGDX 1.7.0

[nikoliazekter]

I got another interesting behaviour. When I use VisTextField after clicking on some button my game starts getting input again but only keyDown events, not keyUp. When I use TextField I just can't get any key events anymore. Btw it's not Tree issue, it can be reproduced anywhere.

[kotcrab]

Should work now.

[nikoliazekter]

After I call VisTextField.focusLost() I still can get only keyDown events. I can get keyUp only after I press some button. You should add FocusManager.getFocus(getStage()); in focusLost().

[kotcrab]

That's not how it works, focusLost and focusGained are listener methods called by FocusManager.
You never manually call them.

To take focus you need to call FocusManager.getFocus(stage) or stage.setKeyboardFocus(null) (but the second way would left focus border still visible on widget)

[nikoliazekter]

Makes sense now, thanks!
