LibGDX: Problems creating custom actor

Question

I am creating a custom class that extends from Actor,just like this:

public class MyActor extends Actor {
ProgressBar bar;
Label nameLabel;
TextButton button;
public MyActor(String name, Skin skin){
    nameLabel = new Label(name, skin);
    button = new TextButton("Whatever",skin);
    bar = new ProgressBar(0f,5f,1f,false,skin);


}
@Override
public void act(float delta) {
    super.act(delta);
    bar.setBounds(getX(), getTop()-getHeight() / 3f, getWidth(), getHeight() / 3f);
    nameLabel.setBounds(getX(), getY()+getHeight() / 3f, getWidth(), getHeight() / 3f);
    button.setBounds(getX(), getY(), getWidth(), getHeight() / 3f);
}

@Override
public void draw(Batch batch, float parentAlpha) {
    super.draw(batch, parentAlpha);
    bar.draw(batch, parentAlpha);
    nameLabel.draw(batch, parentAlpha);
    button.draw(batch,parentAlpha);
} }

Then I try to add it to a Table:

Table myTable = new Table();
myTable.add(myActor).row();

But it always gets drawn in the 0,0 coordinates!, what am I doing wrong? Do I have to override another method?

Answer 1

I know its late but it might help someone, basically when we create actors, in the act() we'll have to set its layout boundary relative to the parent. Layout boundary helps identify the size of the custom actor.

someActor.setBounds( getParent().getX()+getX(), getParent.getY()+getY(), someActor.getPrefWidth(), someActor.getPrefHeight() );

Answer 2

I ran into a similar problem where despite multiple instances of my actor in table.add(myActor) they just stacked on top of each other. That is they weren't put into separate rows/columns visually using scene2d's Table.

I updated myActor to extend Widget (instead of extending Actor) and implemented getPrefWidth and getPrefHeight which solved the problem.
