public class SpringConstraintHelper

extends Object

implements NoAdd

Helper class for constructing a spring constraint. A spring constraint can be very tricky to set up.

Given a dimension (x or y), there three types of constraint. the top/left constraint, the width/height constraints, and the bottom/right constraints. Only two constraints can be active for a given component in one dimension, since the third can be inferred from the other two. Thus, if you want to set the constraint for both sides of a component, width and height constraints, which are present by default, must be cleared.

Since:

CookSwing 1.0
