LayoutManager2 (Sample Document)

All Superinterfaces:

LayoutManager

All Known Implementing Classes:

BorderLayout, CardLayout, GridBagLayout

public interface LayoutManager2 extends LayoutManager

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.

Methods
	Modifier and Type	Method and Description
	addLayoutComponent	`void` addLayoutComponent(Component comp, java.lang.Object constraints) Adds the specified component to the layout, using the specified constraint object. void addLayoutComponent(Component comp, java.lang.Object constraints) Adds 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.
	addLayoutComponent	`void` addLayoutComponent(java.lang.String name, Component comp) If the layout manager uses a per-component string, adds the component `comp` to the layout, associating it with the string specified by `name`. void addLayoutComponent(java.lang.String name, Component comp) Description copied from interface: `LayoutManager` If the layout manager uses a per-component string, adds the component `comp` to the layout, associating it with the string specified by `name`. Parameters: `name` - the string to be associated with the component `comp` - the component to be added
	getLayoutAlignmentX	`float` getLayoutAlignmentX(Container target) Returns the alignment along the x axis. 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.
	getLayoutAlignmentY	`float` getLayoutAlignmentY(Container target) Returns the alignment along the y axis. 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.
	invalidateLayout	`void` invalidateLayout(Container target) Invalidates the layout, indicating that if the layout manager has cached information it should be discarded. void invalidateLayout(Container target) Invalidates the layout, indicating that if the layout manager has cached information it should be discarded.
	layoutContainer	`void` layoutContainer(Container parent) Lays out the specified container. void layoutContainer(Container parent) Description copied from interface: `LayoutManager` Lays out the specified container. Parameters: `parent` - the container to be laid out
	maximumLayoutSize	`Dimension` maximumLayoutSize(Container target) Calculates the maximum size dimensions for the specified container, given the components it contains. Dimension maximumLayoutSize(Container target) Calculates the maximum size dimensions for the specified container, given the components it contains. See Also: `Component.getMaximumSize()`, `LayoutManager`
	minimumLayoutSize	`Dimension` minimumLayoutSize(Container parent) Calculates the minimum size dimensions for the specified container, given the components it contains. Dimension minimumLayoutSize(Container parent) Description copied from interface: `LayoutManager` Calculates the minimum size dimensions for the specified container, given the components it contains. Parameters: `parent` - the component to be laid out See Also: `LayoutManager.preferredLayoutSize(java.awt.Container)`
	preferredLayoutSize	`Dimension` preferredLayoutSize(Container parent) Calculates the preferred size dimensions for the specified container, given the components it contains. Dimension preferredLayoutSize(Container parent) Description copied from interface: `LayoutManager` Calculates the preferred size dimensions for the specified container, given the components it contains. Parameters: `parent` - the container to be laid out See Also: `LayoutManager.minimumLayoutSize(java.awt.Container)`
	removeLayoutComponent	`void` removeLayoutComponent(Component comp) Removes the specified component from the layout. void removeLayoutComponent(Component comp) Description copied from interface: `LayoutManager` Removes the specified component from the layout. Parameters: `comp` - the component to be removed
