Class PsSlotLayout

java.lang.Object

jv.objectGui.PsSlotLayout

All Implemented Interfaces:

java.awt.LayoutManager, java.io.Serializable

public final class PsSlotLayout
extends java.lang.Object
implements java.awt.LayoutManager, java.io.Serializable

Layout manager generalizes GridLayout(1,n) where each component may occupy more than one slot in a horizontal row.

The following example creates a horizontal panel which has three slots. The first slot is occupied with a label and the remaining two slots are filled with a TextField.

 Example usage:
    panel.setLayout(new PsSlotLayout(3));
    panel.add("1", new Label("Name"));
    panel.add("2", new TextField());
 

Currently, components cannot be removed from this layout manager once they have been added. This may be implemented later.
