LibGDX窗口中有一个单元困扰我

Question

I think I might have found an issue in LibGDX, but before opening an issue in their GitHub, I thought it would be better to discuss it here because maybe I am wrong.

This is what is happening to me:

I have a class named Information extending Window , where I show the information about the characters of my game. Since I need to update the labels dynamically, I thought it would be better to simply remove all the actors inside the Window each time I call setVisible(false) . It worked before. So this is my code:

public class Information extends Window {

private final static String TAG = Information.class.getName();
private Unit calledBy; //Variable to know who is calling


public Information (Skin skin) {

    //Setting the attributes
    super("Information", skin);
    this.setPosition(0, 0);
    this.setBounds(this.getX(), this.getY(), Constants.INFORMATION_WIDTH, Constants.INFORMATION_HEIGHT);
    this.setVisible(false);

}

@Override
public void setVisible(boolean visible) {
    if (!visible){
        SnapshotArray<Actor> actors = this.getChildren();
        while (actors.size > 0){
            actors.get(0).remove();
        }
    } else {
        this.add(new Label("Name: " + getCalledBy().getName(), getSkin()));
        this.row();
        this.add(new Label("Attack: " + getCalledBy().getAttack(), getSkin()));
        this.row();
        this.add(new Label("Defense: " + getCalledBy().getDefense(), getSkin()));
        this.row();
        this.add(new Label("Health: " + getCalledBy().getHealth(), getSkin()));
    }
    super.setVisible(visible);
}   

So, every time I call setVisible , I create or erase the actors. The thing is that the first time I call the method, it is working perfectly, but the second and successive times, it appears a Cell with no info besides the Name of the character.

I debugged the creation of the Actors and the deletion of the same and all seems to be working perfectly.

So I was about to open an issue in LibGDX's GitHub, but if someone knows why this is happening to me, I will prefer it.

Thanks in advance!

Ok! So I am responding my own question in case someone needs it.

Thanks to Tenfour04 for his comment, since it helped me to find it.

The correct method to call was clearChildren() . This is my new code:

    public void setVisible(boolean visible) {
    if (!visible){
        this.clearChildren();
    } else {
        this.add(new Label("Name: " + getCalledBy().getName(), getSkin()));
        this.row();
        this.add(new Label("Attack: " + getCalledBy().getAttack(), getSkin()));
        this.row();
        this.add(new Label("Defense: " + getCalledBy().getDefense(), getSkin()));
        this.row();
        this.add(new Label("Health: " + getCalledBy().getHealth(), getSkin()));
    }
    super.setVisible(visible);
}

Hope this helps someone else in the future.
