Class Tab

java.lang.Object
  com.smartgwt.client.core.JsObject
      com.smartgwt.client.core.DataClass
          com.smartgwt.client.core.RefDataClass
              com.smartgwt.client.widgets.tab.Tab

All Implemented Interfaces:

HasHandlers, HasTabDeselectedHandlers, HasTabSelectedHandlers

public class Tab
extends RefDataClass
implements HasTabDeselectedHandlers, HasTabSelectedHandlers

Tabs are specified as objects, not class instances. For example, when developing in JavaScript, a typical initialization block for a TabSet would look like this:

  TabSet.create({
      tabs: [
          {title: "tab1", pane: "pane1"},
          {title: "tab2"}
      ]
  });
  

And in XML:

  <TabSet>
     <tabs>
         <Tab title="tab1" pane="pane1"/>
         <Tab title="tab2"/>
     </tabs>
  </TabSet>

The underlying SmartClient class of the returned canvas depends on #getUseSimpleTabs. If this property is false, the returned canvas will be a ImgTab instance. If true the canvas will be a com.smartgwt.client.widgets.tab.Button instance. Note that you can make use of ImgTab APIs by using the getJsObj() and create() APIs to "cast" to the appropriate type - for example:
ImgTab liveTab = ImgTab.create(myTabSet.getTabCanvas(2).getJsObj());

Returns:

live Canvas for this tab in a tabSet.
