public class VerticalGroup
extends WidgetGroup

A group that lays out its children on top of each other in a single column. This can be easier than using Table when actors need to be inserted in the middle of the group.

The preferred width is the largest preferred width of any child. The preferred height is the sum of the children's preferred heights. The min size is the preferred size and the max size is 0.

Method Summary

float	getPrefHeight()
float	getPrefWidth()
void	invalidate() Invalidates this actor's layout, causing Layout.layout() to happen the next time Layout.validate() is called.
void	layout() Computes and caches any information needed for drawing and, if this actor has children, positions and sizes each child, calls Layout.invalidate() any each child whose width or height has changed, and calls Layout.validate() on each child.
void	setAlignment(int alignment) Sets the horizontal alignment of the children.
void	setReverse(boolean reverse) If true, the children will be ordered from bottom to top rather than the default top to bottom.
void	setSpacing(float spacing) Sets the space between children.

Method Detail

setAlignment

public void setAlignment(int alignment)

Sets the horizontal alignment of the children. Default is center.

Align

setReverse

public void setReverse(boolean reverse)

If true, the children will be ordered from bottom to top rather than the default top to bottom.

invalidate

public void invalidate()

Description copied from interface: Layout

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

Specified by:

invalidate in interface Layout

Overrides:

invalidate in class WidgetGroup

layout

public void layout()

Description copied from interface: Layout

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

Specified by:

layout in interface Layout

Overrides:

layout in class WidgetGroup

getPrefWidth

public float getPrefWidth()

Specified by:

getPrefWidth in interface Layout

Overrides:

getPrefWidth in class WidgetGroup

getPrefHeight

public float getPrefHeight()

Specified by:

getPrefHeight in interface Layout

Overrides:

getPrefHeight in class WidgetGroup

setSpacing

public void setSpacing(float spacing)

Sets the space between children.
