Class CardLayout

  com.extjs.gxt.ui.client.event.BaseObservable
      com.extjs.gxt.ui.client.widget.Layout
          com.extjs.gxt.ui.client.widget.layout.FitLayout
              com.extjs.gxt.ui.client.widget.layout.CardLayout

All Implemented Interfaces:

Observable

public class CardLayout
extends FitLayout

This layout contains multiple widgets, each fit to the container, where only a single widget can be visible at any given time. This layout style is most commonly used for wizards, tab implementations, etc.

Child Widgets are:

• Sized : Yes - expands to fill parent container.
• Positioned : No - widgets are located at 0,0.

The CardLayout's focal method is setActiveItem(Component). Since only one panel is displayed at a time, the only way to move from one panel to the next is by calling setActiveItem the next panel to display. The layout itself does not provide a mechanism for handling this navigation, so that functionality must be provided by the developer.
