Class LayoutPadding

      org.umber.crucible.old.layout.LayoutPadding

public class LayoutPadding

extends LayoutArea

A block of whitespace used to create flexible padding between other areas. Layout areas must always be connected edge to edge, so padding is the only way to put non-Insert spacing between areas.

Constructor Detail

LayoutPadding

public LayoutPadding(AreaStyle style)

Creates a new instance of LayoutPadding with the given AreaStyle.

Parameters:

style - the style constraints for the area

Method Detail

createPadding

public static LayoutPadding createPadding(int width,
                                          int height)

Creates a new instance of LayoutPadding with the given preferred size. The padding can still shrink to a 1 x 1 square, and expand to infinite size if the layout engine needs it. Padding is atomic.

Parameters:

width - the preferred width

height - the preferred height

Returns:

a newly created padding area

createPadding

public static LayoutPadding createPadding(int width,
                                          int height,
                                          int smallestWidth,
                                          int smallestHeight)

Creates a new instance of LayoutPadding with the given preferred size. The padding also takes on the given smallest constraints. The largest constraints are unbounded. Padding is atomic.

Parameters:

width - the preferred width

height - the preferred height

smallestWidth - the smallest possible width

smallestHeight - the smallest possible height

Returns:

a newly created padding area

isRenderable

public boolean isRenderable()

Determines if this area has renderable content. Layout engines can use this to optimize area traversals. Areas which are not renderable should not expect to pass through to the Renderer. This implementation always returns false, since padding areas should never be passed to the renderer.

Overrides:

isRenderable in class LayoutArea

Returns:

true if this area has visible content

toString

public java.lang.String toString()

Converts the area object into String form.

Overrides:

toString in class LayoutArea

Returns:

a String representation of this object
