Class ScrollPaneLayout

java.lang.Object

javax.swing.ScrollPaneLayout

maspack.widgets.ScrollPaneLayout

All Implemented Interfaces:

java.awt.LayoutManager, java.io.Serializable, javax.swing.ScrollPaneConstants

public class ScrollPaneLayout
extends javax.swing.ScrollPaneLayout

This is an override of ScrollPaneLayout which fixes a bug that occurs when a window containing a scroll pane is repacked. When that occurs, viewport.getViewSize() returns the existing size of the client view window rather than its preferred size, which can cause problems because the existing size is not necessarily the final client size after the repack. To fix this, this class reimplements the preferredLayoutSize method to always use the preferred size of the view client.
