public interface LayoutManager2
Defines an interface for classes that know how to layout Containers based on a layout constraints object. This interface extends the LayoutManager interface to deal with layouts explicitly in terms of constraint objects that specify how and where components should be added to the layout.
This minimal extension to LayoutManager is intended for tool providers who wish to the creation of constraint-based layouts. It does not yet provide full, general support for custom constraint-based layout managers.

Method Summary | |
---|---|
void |
addLayoutComponent(Component comp,
Object constraints)
Adds the specified component to the layout, using the specified constraint object. |

getLayoutAlignmentX(Container target)
Returns the alignment along the x axis. |
float |
getLayoutAlignmentY(Container target)
Returns the alignment along the y axis. |
void |
invalidateLayout(Container target)
Invalidates the layout, indicating that if the layout manager has cached information it should be discarded. |
