Method Detail

layout

public void layout()
Description copied from interface: Layout
Positions and sizes each child of this actor. Subsequent calls will not have any affect unless Layout.invalidate() is called.

Specified by:
layout in interface Layout

draw

public void draw(SpriteBatch batch,
                 float parentAlpha)
Description copied from class: Actor
Draws the Actor. The spriteBatch is configured so that the Actor can draw in its parents coordinate system. The parent's alpha is passed to the method in order for the Actor to multiply it with its own alpha. This will allow FadeIn and other Actions to have an effect even if they are only set on the parent of the Actor.

Overrides:
draw in class Group
Parameters:
batch - the spritebatch to render with
parentAlpha - the parent's alpha value.

invalidate

public void invalidate()
Description copied from interface: Layout
Invalidates the layout, forcing the next call to Layout.layout() to relayout. If an actor is resized or otherwise changed in a way that affects its layout, Layout.invalidate() should be called.

Specified by:
invalidate in interface Layout

getPrefWidth

public float getPrefWidth()
Specified by:
getPrefWidth in interface Layout

getPrefHeight

public float getPrefHeight()
Specified by:
getPrefHeight in interface Layout

getMaxWidth

public float getMaxWidth()
Specified by:
getMaxWidth in interface Layout

getMaxHeight

public float getMaxHeight()
Specified by:
getMaxHeight in interface Layout

getMinWidth

public float getMinWidth()
Specified by:
getMinWidth in interface Layout

getMinHeight

public float getMinHeight()
Specified by:
getMinHeight in interface Layout
