tripleplay.ui.layout.AbsoluteLayout

public class AbsoluteLayout
extends Layout

A layout that positions elements at absolute coordinates (at either their preferred size or at a manually specified size). Constraints are specified like so:

 Group group = new Group(new AbsoluteLayout()).add(
     AbsoluteLayout.at(new Label("+50+50"), 50, 50),
     AbsoluteLayout.at(new Button("100x50+25+25"), 25, 25, 100, 50)
 );

Method Details

uniform

public static AbsoluteLayout.Constraint uniform(BoxPoint where)

Creates a constraint to position an element uniformly. The given box point is used for both the position and the origin. For example, if BoxPoint.BR is used, then the element will be positioned such that its bottom right corner is over the bottom right corner of the group.

at

public static <T extends Element<?>> T at(T elem,
 float x,
 float y)

Positions elem at the specified position, in its preferred size.

at

public static <T extends Element<?>> T at(T elem,
 pythagoras.f.IPoint position)

Positions elem at the specified position, in its preferred size.

at

public static <T extends Element<?>> T at(T elem,
 float x,
 float y,
 float width,
 float height)

Constrains elem to the specified position and size.

at

public static <T extends Element<?>> T at(T elem,
 pythagoras.f.IPoint position,
 pythagoras.f.IDimension size)

Constrains elem to the specified position and size.

at

public static <T extends Element<?>> T at(T elem,
 float x,
 float y,
 Style.HAlign halign,
 Style.VAlign valign)

Positions elem relative to the given position using the given alignments.

at

public static <T extends Element<?>> T at(T elem,
 pythagoras.f.IPoint position,
 Style.HAlign halign,
 Style.VAlign valign)

Positions elem relative to the given position using the given alignments.

at

public static <T extends Element<?>> T at(T elem,
 float x,
 float y,
 float width,
 float height,
 Style.HAlign halign,
 Style.VAlign valign)

Constrains elem to the specified size and aligns it relative to the given position using the given alignments.

at

public static <T extends Element<?>> T at(T elem,
 pythagoras.f.IPoint position,
 pythagoras.f.IDimension size,
 Style.HAlign halign,
