xal.tools.apputils.EdgeLayout

All Implemented Interfaces:

LayoutManager

public class EdgeLayout
extends Object
implements 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 Details

setConstraints

public void setConstraints(Component component,
 int topStrut,
 int leftStrut,
 int bottomStrut,
 int rightStrut,
 int strutBehavior,
 int growBehavior)

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

setConstraints

public void setConstraints(Component component,
 int topStrut,
 int leftStrut,
 int bottomStrut,
 int rightStrut,
 int strutBehavior)

Add the component to the layout at the specified coordinates with the specified struts and strut and no growth.

setConstraints

public void setConstraints(Component component,
 Dimension containerSize,
 int x,
 int y,
 int strutBehavior,
 int growBehavior)

Add the component to the layout at the specified coordinates with the specified strut and growth behaviors. The struts are calculated based on the component's preferred size and the specified container size.

setConstraints

public void setConstraints(Component component,
 Dimension containerSize,
 int x,
 int y,
 int strutBehavior)

Add the component to the layout at the specified coordinates with the specified strut and growth behaviors. The struts are calculated based on the component's preferred size and the specified container size.

add

public void add(Component component,
 Container parent,
 int x,
 int y,
 int strutBehavior,
 int growBehavior)

Add the component to the parent at the specified coordinates with the specified strut and growth behaviors. The struts are calculated based on the component's preferred size and the parent's bounds at the time this method is invoked.

add

public void add(Component component,
