public interface: LayoutManager2 [javadoc | source]

All Implemented Interfaces:
    LayoutManager

All Known Implementing Classes:
    UpdateHandler, OverlayLayout, DefaultToolBarLayout, BasicHorizontalLayoutManager, MetalRootLayout, BasicVerticalLayoutManager, GroupLayout, DefaultMenuLayout, CardLayout, DefaultMenuLayout, GridBagLayout, BoxLayout, SpringLayout, RootLayout, BorderLayout, SynthMenuLayout

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 from java.awt.LayoutManager2 Summary:
addLayoutComponent,   getLayoutAlignmentX,   getLayoutAlignmentY,   invalidateLayout,   maximumLayoutSize
Method from java.awt.LayoutManager2 Detail:
 public  void addLayoutComponent(Component comp,
    Object constraints)
    Adds the specified component to the layout, using the specified constraint object.
 public float getLayoutAlignmentX(Container target)
    Returns the alignment along the x axis. This specifies how the component would like to be aligned relative to other components. The value should be a number between 0 and 1 where 0 represents alignment along the origin, 1 is aligned the furthest away from the origin, 0.5 is centered, etc.
 public float getLayoutAlignmentY(Container target)
    Returns the alignment along the y axis. This specifies how the component would like to be aligned relative to other components. The value should be a number between 0 and 1 where 0 represents alignment along the origin, 1 is aligned the furthest away from the origin, 0.5 is centered, etc.
 public  void invalidateLayout(Container target)
    Invalidates the layout, indicating that if the layout manager has cached information it should be discarded.
 public Dimension maximumLayoutSize(Container target)
    Calculates the maximum size dimensions for the specified container, given the components it contains.
