## com.gwtext.client.widgets
Class Component

    java.lang.Object
      com.google.gwt.user.client.ui.UIObject
          com.google.gwt.user.client.ui.Widget
              com.gwtext.client.widgets.Component

All Implemented Interfaces:
  com.google.gwt.user.client.EventListener, Observable

Direct Known Subclasses:
  BaseItem, BoxComponent, Button, ColorPalette, DatePicker, Editor

    public abstract class Component

extends com.google.gwt.user.client.ui.Widget
implements Observable

Base class for all Ext components. All subclasses of Component can automatically participate in the standard Ext component lifecycle of creation, rendering and destruction. They also have automatic support for basic hide/show and enable/disable behavior. All visual widgets that require rendering into a layout should subclass Component (or BoxComponent if managed box model handling is required).

Every component has a specific xtype. This is the list of all valid xtypes:

     xtype            Class
