      +--javax.swing.plaf.basic.BasicSplitPaneUI.BasicHorizontalLayoutManager

All Implemented Interfaces:
  LayoutManager, LayoutManager2

Direct Known Subclasses:
  BasicSplitPaneUI.BasicVerticalLayoutManager

Enclosing class:
  BasicSplitPaneUI

public class BasicSplitPaneUI.BasicHorizontalLayoutManager
extends Object
implements LayoutManager2

This inner class is marked "public" due to a compiler bug. This class should be treated as a "protected" inner class. Instantiate it only within subclasses of BasicSplitPaneUI.

Field Detail

### sizes

    protected int[] sizes

### components

    protected Component[] components

Method Detail

### layoutContainer

    public void layoutContainer(Container container)

  Does the actual layout.

  Specified by:
    `layoutContainer` in interface `LayoutManager`
  Parameters:
    `container` - the container to be laid out

### addLayoutComponent

    public 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:
    `addLayoutComponent` in interface `LayoutManager`
  Parameters:
    `place` - the string to be associated with the component
    `component` - the component to be added

### minimumLayoutSize

    public Dimension minimumLayoutSize(Container container)

  Returns the minimum size needed to contain the children. The width is the sum of all the childrens min widths and the height is the largest of the childrens minimum heights.

  Specified by:
    `minimumLayoutSize` in interface `LayoutManager`
  Parameters:
    `container` - the component to be laid out
  See Also:
    `LayoutManager.preferredLayoutSize(java.awt.Container)`

### preferredLayoutSize

    public Dimension preferredLayoutSize(Container container)

  Returns the preferred size needed to contain the children. The width is the sum of all the childrens preferred widths and the height is the largest of the childrens preferred heights.

  Specified by:
    `preferredLayoutSize` in interface `LayoutManager`
  Parameters:
    `container` - the container to be laid out
  See Also:
    `LayoutManager.minimumLayoutSize(java.awt.Container)`

### removeLayoutComponent

    public void removeLayoutComponent(Component component)

  Removes the specified component from our knowledge.

  Specified by:
    `removeLayoutComponent` in interface `LayoutManager`
  Parameters:
    `component` - the component to be removed

### addLayoutComponent

    public void addLayoutComponent(Component comp,
                                   Object constraints)

  Adds the specified component to the layout, using the specified constraint object.

  Specified by:
    `addLayoutComponent` in interface `LayoutManager2`
  Parameters:
    `comp` - the component to be added
    `constraints` - where/how the component is added to the layout.

### getLayoutAlignmentX

    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.

  Specified by:
    `getLayoutAlignmentX` in interface `LayoutManager2`

### getLayoutAlignmentY

    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.

  Specified by:
    `getLayoutAlignmentY` in interface `LayoutManager2`

### invalidateLayout

    public 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:
    `invalidateLayout` in interface `LayoutManager2`

### maximumLayoutSize

    public Dimension maximumLayoutSize(Container target)

  Returns the maximum layout size, which is Integer.MAX_VALUE in both directions.

  Specified by:
    `maximumLayoutSize` in interface `LayoutManager2`
  See Also:
    `Component.getMaximumSize()`, `LayoutManager`

### resetToPreferredSizes

    public void resetToPreferredSizes()

  Marks the receiver so that the next time this instance is laid out it'll ask for the preferred sizes.

### resetSizeAt

    protected void resetSizeAt(int index)

  Resets the size of the Component at the passed in location.

### setSizes

    protected void setSizes(int[] newSizes)

  Sets the sizes to `newSizes`.

### getSizes

    protected int[] getSizes()

  Returns the sizes of the components.

### getPreferredSizeOfComponent

    protected int getPreferredSizeOfComponent(Component c)

  Returns the width of the passed in Components preferred size.

### getSizeOfComponent

    protected int getSizeOfComponent(Component c)

  Returns the width of the passed in component.

### getAvailableSize

    protected int getAvailableSize(Dimension containerSize,
                                   Insets insets)

  Returns the available width based on the container size and Insets.

### getInitialLocation

    protected int getInitialLocation(Insets insets)

  Returns the left inset, unless the Insets are null in which case 0 is returned.

### setComponentToSize

    protected void setComponentToSize(Component c,
                                      int size,
                                      int location,
                                      Insets insets,
                                      Dimension containerSize)

  Sets the width of the component c to be size, placing its x location at location, y to the insets.top and height to the containersize.height less the top and bottom insets.

### updateComponents

    protected void updateComponents()

  Determines the components. This should be called whenever a new instance of this is installed into an existing SplitPane.
