All Implemented Interfaces:

java.awt.LayoutManager

public class EdgeLayout

extends java.lang.Object

implements java.awt.LayoutManager

EdgeLayout allows the developer a simpler mechanism for layout of components than the GridBagLayout without sacrificing powerful layout capability. The developer simply defines the behavior of motion for the component with respect to its parent and how the component grows. The motion is specified by struts between the edges of the the component and the corresponding edges of the parent container. For example, if you use a RIGHT strut, the component is bound to its parent's right edge according to the initial placement of the component. That is, the gap between the right edges of the parent and its container is preserved. If the component is bound left and right to its parent and the component is constrained to grow horizontally, the component will maintain the left and right gaps with its parent container and grow accordingly.

Method Detail

setConstraints

public void setConstraints(java.awt.Component component,
                           int topStrut,
                           int leftStrut,

                           int strutBehavior,
                           int growBehavior)

Add the component to the layout at the specified coordinates with the specified struts and strut and growth behaviors.
