  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 children's min widths and the height is the largest of the children's 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 preferred widths of the children and the height is the largest preferred height of the children.

  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.
