implements LayoutManager, ScrollPaneConstants, Serializable

Warning: serialized objects of this class will not be compatible with future swing releases. The current serialization support is appropriate for short term storage or RMI between Swing1.0 applications. It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.

Layout the scrollpane according to the following constraints:

• The row header, if present and visible, gets its preferred height and the viewports width.
  minimumLayoutSize(Container)
  The minimum size of a ScrollPane is the size of the insets plus minimum size of the viewport, plus the scrollpanes viewportBorder insets, plus the minimum size of the visible headers, plus the minimum size of the scrollbars whose displayPolicy isn't NEVER.
  preferredLayoutSize(Container)
  The preferred size of a ScrollPane is the size of the insets plus preferred size of the viewport plus the preferred size of the visible headers, plus the preferred size of the scrollbars that will appear given the current view and the current scrollbar displayPolicies.

 public Dimension preferredLayoutSize(Container parent)

The preferred size of a ScrollPane is the size of the insets plus preferred size of the viewport plus the preferred size of the visible headers, plus the preferred size of the scrollbars that will appear given the current view and the current scrollbar displayPolicies.

Returns:

The preferred size of the viewport and any scrollbars.

 public Dimension minimumLayoutSize(Container parent)

The minimum size of a ScrollPane is the size of the insets plus minimum size of the viewport, plus the scrollpanes viewportBorder insets, plus the minimum size of the visible headers, plus the minimum size of the scrollbars whose displayPolicy isn't NEVER.

 public void layoutContainer(Container parent)

Layout the scrollpane according to the following constraints:

• The row header, if present and visible, gets its preferred height and the viewports width.
• The column header, if present and visible, gets its preferred width and the viewports height.
• If a vertical scrollbar is needed, i.e. if the viewports extent height is smaller than its view height or if the displayPolicy is ALWAYS, it's treated like the row header wrt it's dimensions and it's made visible.
• If a horizontal scrollbar is needed it's treated like the column header (and see the vertical scrollbar item).
• If the scrollpane has a non-null viewportBorder, then space is allocated for that.
• The viewport gets the space available after accounting for the previous constraints.
• The corner components, if provided, are aligned with the ends of the scrollbars and headers. If there's a vertical scrollbar the right corners appear, if there's a horizontal scrollbar the lower corners appear, a row header gets left corners and a column header gets upper corners.
