| java.awt.LayoutManager2
All known Subclasses: java.awt.CardLayout, java.awt.BorderLayout, java.awt.GridBagLayout,
| LayoutManager2 | | public interface LayoutManager2 extends LayoutManager(Code) | | 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.

| addLayoutComponent | | void addLayoutComponent(Component comp, Object constraints)(Code) | | Adds the specified component to the layout, using the specified
constraint object.
Parameters:
comp - the component to be added
Parameters:
constraints - where/how the component is added to the layout. |
| getLayoutAlignmentX | | public float getLayoutAlignmentX(Container target)(Code) | | 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.
|
| getLayoutAlignmentY | | public float getLayoutAlignmentY(Container target)(Code) | | 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.
|
| invalidateLayout | | public void invalidateLayout(Container target)(Code) | | Invalidates the layout, indicating that if the layout manager
has cached information it should be discarded.
