Method Details

invalidate

public void invalidate()

Description copied from class: Element

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

Overrides:

invalidate in class WidgetGroup

add

public void add(Element actor)

layout

public void layout()

Description copied from class: Element

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

Overrides:

layout in class WidgetGroup

getPrefWidth

public float getPrefWidth()

Overrides:

getPrefWidth in class WidgetGroup

getPrefHeight

public float getPrefHeight()

Overrides:

getPrefHeight in class WidgetGroup

getMinWidth

public float getMinWidth()

Overrides:

getMinHeight

public float getMinHeight()

Overrides:
