public class SpringLayoutextends Objectimplements LayoutManager2A SpringLayout lays out the children of its associated container according to a set of constraints. See How to Use SpringLayout in The Java Tutorial for examples of using SpringLayout.Each constraint, represented by a Spring object, controls the vertical or horizontal distance between two component edges. The edges can belong to any child of the container, or to the container itself. For example, the allowable width of a component can be expressed using a constraint that controls the distance between the west (left) and east (right) edges of the component. The allowable y coordinates for a component can be expressed by constraining the distance between the north (top) edge of the component and the north edge of its container.Every child of a SpringLayout-controlled container, as well as the container itself, has exactly one set of constraints associated with it. These constraints are represented by a SpringLayout.Constraints object. By default, SpringLayout creates constraints that make their associated component have the minimum, preferred, and maximum sizes returned by the component's Component.getMinimumSize(), Component.getPreferredSize(), and Component.getMaximumSize() methods. The x and y positions are initially not constrained, so that until you constrain them the Component will be positioned at 0,0 relative to the Insets of the parent Container.You can change a component's constraints in several ways. You can use one of the putConstraint methods to establish a spring linking the edges of two components within the same container. Or you can get the appropriate SpringLayout.Constraints object using getConstraints and then modify one or more of its springs. Or you can get the spring for a particular edge of a component using getConstraint, and modify it. You can also associate your own SpringLayout.Constraints object with a component by specifying the constraints object when you add the component to its container (using Container.add(Component, Object)).
