A stack is a container that sizes its children to its size and positions them at 0,0 on top of each other.

The preferred and min size of the stack is the largest preferred and min size of any children. The max size of the stack is the smallest max size of any children.

public void
invalidate()

Overrides com.badlogic.gdx.scenes.scene2d.ui.WidgetGroup.invalidate.

Implements com.badlogic.gdx.scenes.scene2d.utils.Layout.invalidate.

Invalidates this actor's layout, causing layout() to happen the next time validate() is called.

public void
layout()

Overrides com.badlogic.gdx.scenes.scene2d.ui.WidgetGroup.layout.

Implements com.badlogic.gdx.scenes.scene2d.utils.Layout.layout.

Computes and caches any information needed for drawing and, if this actor has children, positions and sizes each child, calls invalidate() on any each child whose width or height has changed, and calls validate() on each child.

Overrides com.badlogic.gdx.scenes.scene2d.ui.WidgetGroup.invalidate.

Implements com.badlogic.gdx.scenes.scene2d.utils.Layout.invalidate.

Doc from com.badlogic.gdx.scenes.scene2d.utils.Layout.invalidate.

Invalidates this actor's layout, causing layout() to happen the next time validate() is called. This method should be called when state changes in the actor that requires a layout but does not change the minimum, preferred, maximum, or actual size of the actor (meaning it does not affect the parent actor's layout).

public void layout()

Overrides com.badlogic.gdx.scenes.scene2d.ui.WidgetGroup.layout.

Implements com.badlogic.gdx.scenes.scene2d.utils.Layout.layout.

Doc from com.badlogic.gdx.scenes.scene2d.utils.Layout.layout.

Computes and caches any information needed for drawing and, if this actor has children, positions and sizes each child, calls invalidate() on any each child whose width or height has changed, and calls validate() on each child. This method should almost never be called directly, instead validate() should be used.
