      If enabled, the tab will collapse to show just its icon when showing the title would cause overflow of a containing `TabBar`. While collapsed, the tab will show its title on hover, unless an explicit hover has been specified such as by `prompt`.
      Parameters:
        `canAdaptWidth` - New canAdaptWidth value. Default value is false
      Returns:
        `Tab` instance, for chaining setter calls
      See Also:

        `Button.getCanAdaptWidth()`, `Canvas.getCanAdaptWidth()`

    - #### getCanClose

          public java.lang.Boolean getCanClose()

      Determines whether this tab should show a close icon allowing the user to dismiss the tab by clicking on the close icon directly. The URL for the close icon's image will be derived from `TabSet.closeTabIcon` by default, but may be overridden by explicitly specifying `closeIcon`.

      If unset or null, this property is derived from `TabSet.canCloseTabs`.

      Note that setting `canClose` means that `icon` cannot be used, because it's used for the `closeIcon` - see `TabSet.canCloseTabs` for a workaround.

      Returns:
        Current canClose value. Default value is null
      See Also:
        `com.smartgwt.client.widgets.tab.TabSet#closeClick`, Closeable Tabs Example

    - #### getCanEditTitle

      If specified, overrides the `TabSet.canEditTabTitles` setting, for this one tab only.

      Note that the TabSet's `titleEditEvent` must be set to a supported `TabTitleEditEvent` in order for users to be able to edit this tab's title.

      Returns:
        Current canEditTitle value. Default value is null
      See Also:
        `TabSet.getCanEditTabTitles()`, User-Editable Titles Example

    - #### setCanReorder

          public Tab setCanReorder(java.lang.Boolean canReorder)

      If `TabSet.canReorderTabs` is set to `true`, setting `canReorder` explicitly to `false` for some tab will disallow drag-reordering of this tab. Has no effect if `canReorderTabs` is not true at the tabSet level.

      Note that this setting also disallows a reorder of another tab into the slot before or following this tab. This means for tabs located at the beginning or end of the tab-bar, users cannot changing the index of the tab by dropping another before or after it. However if you have a `canReorder:false` tab which is not at the beginning or end of the tab bar, users can drag reorder other tabs around it which may ultimately change its position.

      Parameters:
        `canReorder` - New canReorder value. Default value is null
      Returns:
        `Tab` instance, for chaining setter calls

      Note that this setting also disallows a reorder of another tab into the slot before or following this tab. This means for tabs located at the beginning or end of the tab-bar, users cannot changing the index of the tab by dropping another before or after it. However if you have a `canReorder:false` tab which is not at the beginning or end of the tab bar, users can drag reorder other tabs around it which may ultimately change its position.

      Returns:
        Current canReorder value. Default value is null

      Returns:
        Current closeIcon value. Default value is null
      See Also:
        `SCImgURL`

    - #### getCloseIconSize

      Returns:
        Current disabled value. Default value is null

    - #### setEnableWhen

          public Tab setEnableWhen(AdvancedCriteria enableWhen)

      Criteria to be evaluated to determine whether this Tab should be enabled. Re-evaluated whenever data in the `tab.ruleScope` changes.

      It works the same as `Canvas.enableWhen`

      Parameters:
        `enableWhen` - New enableWhen value. Default value is null
      Returns:
        `Tab` instance, for chaining setter calls
      See Also:
        `RuleCriteria overview and related methods`

    - #### getEnableWhen

          public AdvancedCriteria getEnableWhen()

      Criteria to be evaluated to determine whether this Tab should be enabled. Re-evaluated whenever data in the `tab.ruleScope` changes.

      It works the same as `Canvas.enableWhen`

        Current enableWhen value. Default value is null
      See Also:
        `RuleCriteria overview and related methods`

    - #### getIcon

          public java.lang.String getIcon()

      If specified, this tab will show an icon next to the tab title.

      NOTE: if you enable `closeable tabs`, `tab.icon` is used for the close icon. `TabSet.canCloseTabs` describes a workaround to enable both a `closeIcon` and a second icon to be shown.

      Use `TabSet.tabIconClick()` to add an event handler specifically for clicks on the icon.

      If a tab `becomes disabled`, a different icon will be loaded by adding a suffix to the image name (see `Button.icon`).

      You should specify a size for the icon via `iconSize` or `iconWidth` and `iconHeight`. Without an explicitly specified size, tabs may be drawn overlapping or with gaps the first time a page is loaded, because the icon is not cached and therefore its size isn't known.

      Returns:
        Current icon value. Default value is null
      See Also:
        `TabClickEvent`, `SCImgURL`, Orientation Example

        Current iconHeight value. Default value is null

    - #### getIconSize

          public java.lang.Integer getIconSize()

      If `icon` is specified, this property may be used to specify a size for the icon. Per side sizing may be specified instead via `iconWidth` and `iconHeight`.
      Returns:
        Current iconSize value. Default value is 16

    - #### getIconWidth

          public java.lang.Integer getIconWidth()

      If `icon` is specified, this property may be used to specify a width for the icon.

          public void setIcon(java.lang.String icon,
                              int iconSize)

      If specified, this tab will show an icon next to the tab title. Note that as with `icon`, the URL of a tabs icon will be updated to reflect disabled state.

      Parameters:
        `icon` - icon Default value is null
        `iconSize` - the icon size

      If unset or null, this property is derived from `TabSet.canCloseTabs`.

      Note that setting `canClose` means that `icon` cannot be used, because it's used for the `closeIcon` - see `TabSet.canCloseTabs` for a workaround.

      Parameters:

    - #### setPane

          public void setPane(Canvas pane)

      Specifies the pane associated with this tab. You can change the pane associated with a given tab after the TabSet has been created by calling `TabSet.updateTab(int, com.smartgwt.client.widgets.Canvas)`

    - #### setContextMenu

          public void setContextMenu(Menu contextMenu)

      Context menu to show for this tab.
      Parameters:
        `contextMenu` - contextMenu Default value is null

    - #### getContextMenu

    - #### getTabSet

          public TabSet getTabSet()

    - #### setTabSet

          public void setTabSet(TabSet tabSet)

    - #### getTabCanvas

          public StatefulCanvas getTabCanvas()

      Returns the live Canvas used to represent this tab in a tabSet. Will return null if this Tab has not been added to a TabSet or if the tabset is not yet drawn.

      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.
