Method Detail- 
layoutContainerpublic void layoutContainer(Container container) Does the actual layout.- Specified by:
- layoutContainerin interface- LayoutManager
- Parameters:
- container- the container to be laid out
 
 - 
addLayoutComponentpublic void addLayoutComponent(String place, Component component) Adds the component at place. Place must be one of JSplitPane.LEFT, RIGHT, TOP, BOTTOM, or null (for the divider).- Specified by:
- addLayoutComponentin interface- LayoutManager
- Parameters:
- place- the string to be associated with the component
- component- the component to be added
 
 - 
minimumLayoutSizepublic Dimension minimumLayoutSize(Container container) Returns the minimum size needed to contain the children. The width is the sum of all the children's min widths and the height is the largest of the children's minimum heights.- Specified by:
- minimumLayoutSizein interface- LayoutManager
- Parameters:
- container- the component to be laid out
- Returns:
- the minimum dimension for the container
- See Also:
- LayoutManager.preferredLayoutSize(java.awt.Container)
 
 - 
preferredLayoutSizepublic Dimension preferredLayoutSize(Container container) Returns the preferred size needed to contain the children. The width is the sum of all the preferred widths of the children and the height is the largest preferred height of the children.- Specified by:
- preferredLayoutSizein interface- LayoutManager
- Parameters:
- container- the container to be laid out
- Returns:
- the preferred dimension for the container
- See Also:
- LayoutManager.minimumLayoutSize(java.awt.Container)
 
 - 
removeLayoutComponentpublic void removeLayoutComponent(Component component) Removes the specified component from our knowledge.- Specified by:
- removeLayoutComponentin interface- LayoutManager
- Parameters:
- component- the component to be removed
 
 - 
addLayoutComponentpublic void addLayoutComponent(Component comp, Object constraints) Adds the specified component to the layout, using the specified constraint object.- Specified by:
- addLayoutComponentin interface- LayoutManager2
- Parameters:
- comp- the component to be added
- constraints- where/how the component is added to the layout.
 
 - 
getLayoutAlignmentXpublic 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.- Specified by:
- getLayoutAlignmentXin interface- LayoutManager2
- Parameters:
- target- the target container
- Returns:
- the x-axis alignment preference
 
 - 
getLayoutAlignmentYpublic 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.- Specified by:
- getLayoutAlignmentYin interface- LayoutManager2
- Parameters:
- target- the target container
- Returns:
- the y-axis alignment preference
 
 - 
invalidateLayoutpublic void invalidateLayout(Container c) Does nothing. If the developer really wants to change the size of one of the views JSplitPane.resetToPreferredSizes should be messaged.- Specified by:
- invalidateLayoutin interface- LayoutManager2
- Parameters:
- c- the target container
 
 - 
maximumLayoutSizepublic Dimension maximumLayoutSize(Container target) Returns the maximum layout size, which is Integer.MAX_VALUE in both directions.- Specified by:
- maximumLayoutSizein interface- LayoutManager2
- Parameters:
- target- the target container
- Returns:
- the maximum size of the container
- See Also:
- Component.getMaximumSize(),- LayoutManager
 
 - 
resetToPreferredSizespublic void resetToPreferredSizes() Marks the receiver so that the next time this instance is laid out it'll ask for the preferred sizes.
 - 
resetSizeAtprotected void resetSizeAt(int index) Resets the size of the Component at the passed in location.- Parameters:
- index- the index of a component
 
 - 
setSizesprotected void setSizes(int[] newSizes) Sets the sizes tonewSizes.- Parameters:
- newSizes- the new sizes
 
 - 
getSizesprotected int[] getSizes() Returns the sizes of the components.- Returns:
- the sizes of the components
 
 - 
getPreferredSizeOfComponentprotected int getPreferredSizeOfComponent(Component c) Returns the width of the passed in Components preferred size.- Parameters:
- c- a component
- Returns:
- the preferred width of the component
 
 - 
getSizeOfComponentprotected int getSizeOfComponent(Component c) Returns the width of the passed in component.- Parameters:
- c- a component
- Returns:
- the width of the component
 
 - 
getAvailableSizeprotected int getAvailableSize(Dimension containerSize, Insets insets) Returns the available width based on the container size andInsets.- Parameters:
- containerSize- a container size
- insets- an insets
- Returns:
- the available width
 
 - 
getInitialLocationprotected int getInitialLocation(Insets insets) Returns the left inset, unless theInsetsare null in which case 0 is returned.- Parameters:
- insets- the insets
- Returns:
- the left inset
 
 - 
setComponentToSizeprotected void setComponentToSize(Component c, int size, int location, Insets insets, Dimension containerSize) Sets the width of the componentcto besize, placing its x location atlocation, y to theinsets.topand height to thecontainerSize.heightless the top and bottom insets.- Parameters:
- c- a component
- size- a new width
- location- a new X coordinate
- insets- an insets
- containerSize- a container size
 
 - 
updateComponentsprotected void updateComponents() Determines the components. This should be called whenever a new instance of this is installed into an existing SplitPane.
