Class StackLayout

java.lang.Object
org.jdesktop.swingx.StackLayout
All Implemented Interfaces:
LayoutManager, LayoutManager2
public class StackLayout extends Object implements LayoutManager2

StackLayout is a Swing layout aimed to act as the layers stack of most popuplar graphics editing tools like The GIMP or Photoshop. While similar to CardLayout, this layout displays all the components of the container. If you are using non-rectangular components (i.e. transparent) you will see them from top to bottom of the stack.

When using this layout, each component can be added in the container either on top of the stack or at the bottom:

 JPanel panel = new JPanel(new StackLayout());
 panel.add(new JLabel("On top"),    StackLayout.TOP);
 panel.add(new JLabel("At bottom"), StackLayout.BOTTOM);
If you don't specify the constraint, the component will be added at the top of the components stack.

All the components managed by this layout will be given the same size as the container itself. The minimum, maximum and preferred size of the container are based upon the largest minimum, maximum and preferred size of the children components.

StackLayout works only with JSE 1.5 and Java SE 6 and greater.
