- All Superinterfaces:
- LayoutManager
- All Known Implementing Classes:
- BasicSplitPaneUI.BasicHorizontalLayoutManager,- BasicSplitPaneUI.BasicVerticalLayoutManager,- BorderLayout,- BoxLayout,- CardLayout,- DefaultMenuLayout,- GridBagLayout,- GroupLayout,- JRootPane.RootLayout,- OverlayLayout,- SpringLayout
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 create constraint-based layouts.
 It does not yet provide full, general support for custom
 constraint-based layout managers.

Method SummaryModifier and TypeMethodDescriptionvoidaddLayoutComponent(Component comp, Object constraints) Adds the specified component to the layout, using the specified constraint object.floatgetLayoutAlignmentX(Container target) Returns the alignment along the x axis.floatgetLayoutAlignmentY(Container target) Returns the alignment along the y axis.voidinvalidateLayout(Container target) Invalidates the layout, indicating that if the layout manager has cached information it should be discarded.maximumLayoutSize(Container target) Calculates the maximum size dimensions for the specified container, given the components it contains.Methods declared in interface java.awt.LayoutManageraddLayoutComponent, layoutContainer, minimumLayoutSize, preferredLayoutSize, removeLayoutComponent

Method Details- 
addLayoutComponentAdds the specified component to the layout, using the specified constraint object.- Parameters:
- comp- the component to be added
- constraints- where/how the component is added to the layout.
 
- 
maximumLayoutSizeCalculates the maximum size dimensions for the specified container, given the components it contains.- Parameters:
- target- the target container
- Returns:
- the maximum size of the container

- 
getLayoutAlignmentXReturns 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.- Parameters:
- target- the target container
- Returns:
- the x-axis alignment preference
 
- 
getLayoutAlignmentYReturns 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.- Parameters:
- target- the target container
- Returns:
- the y-axis alignment preference
 
- 
invalidateLayoutInvalidates the layout, indicating that if the layout manager has cached information it should be discarded.- Parameters:
- target- the target container
