          public Listfoot()

  - ### Method Detail

    - #### getListbox

          public Listbox getListbox()

      Returns the list box that it belongs to.

      It is the same as `AbstractComponent.getParent()`.

    - #### setWidth

          public void setWidth​(java.lang.String width)

      Deprecated.
      as of release 6.0.0. To control the size of Listbox related components, please refer to `Listbox` and `Listheader` instead.
      Description copied from class: `HtmlBasedComponent`
      Sets the width. If null, the best fit is used.
      Overrides:
        `setWidth` in class `HtmlBasedComponent`
      See Also:
        `HtmlBasedComponent.setWidthDirectly(java.lang.String)`, `AbstractComponent.disableClientUpdate(boolean)`

    - #### setHflex

          public void setHflex​(java.lang.String flex)

      Deprecated.
      as of release 6.0.0. To control the size of Listbox related components, please refer to `Listbox` and `Listheader` instead.
      Description copied from class: `HtmlBasedComponent`
      Sets horizontal flex hint of this component.

      Number flex indicates how this component's container distributes remaining empty space among its children horizontally. Flexible component grow and shrink to fit their given space. Flexible components with larger flex values will be made larger than components with lower flex values, at the ratio determined by all flexible components. The actual flex value is not relevant unless there are other flexible components within the same container. Once the default sizes of components in a container are calculated, the remaining space in the container is divided among the flexible components, according to their flex ratios.

      Specify a flex value of negative value, 0, or "false" has the same effect as leaving the flex attribute out entirely. Specify a flex value of "true" has the same effect as a flex value of 1.

      Special flex hint, "min", indicates that the minimum space shall be given to this flexible component to enclose all of its children components. That is, the flexible component grow and shrink to fit its children components.

      Overrides:
        `setHflex` in class `HtmlBasedComponent`
      Parameters:
        `flex` - horizontal flex hint of this component.
      See Also:
        `HtmlBasedComponent.setVflex(java.lang.String)`, `HtmlBasedComponent.getHflex()`

    - #### beforeParentChanged

          public void beforeParentChanged​(Component parent)

      Description copied from class: `AbstractComponent`
      Default: If parent is null, execute the @Destroy method if any.
      Specified by:
        `beforeParentChanged` in interface `ComponentCtrl`
      Overrides:
        `beforeParentChanged` in class `AbstractComponent`
      Parameters:
        `parent` - the new parent. If null, it means detachment.
      See Also:
        `ComponentCtrl.beforeParentChanged(org.zkoss.zk.ui.Component)`

    - #### beforeChildAdded

          public void beforeChildAdded​(Component child,
                                       Component refChild)

      Description copied from class: `AbstractComponent`
      Default: does nothing.
      Specified by:
        `beforeChildAdded` in interface `ComponentCtrl`
      Overrides:
        `beforeChildAdded` in class `AbstractComponent`
      Parameters:
        `child` - the child to be added (never null).
        `refChild` - another child component that the new child will be inserted before it. If null, the new child will be the last child.
      See Also:
        `ComponentCtrl.beforeChildAdded(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.Component)`

    - #### getZclass

          public java.lang.String getZclass()

      Description copied from class: `HtmlBasedComponent`
      Returns the ZK Cascading Style class for this component. It usually depends on the implementation of the mold (`AbstractComponent.getMold()`).

      Default: null (the default value depends on element).

      `HtmlBasedComponent.setZclass(java.lang.String)`) will completely replace the default style of a component. In other words, the default style of a component is associated with the default value of `HtmlBasedComponent.getZclass()`. Once it is changed, the default style won't be applied at all. If you want to perform small adjustments, use `HtmlBasedComponent.setSclass(java.lang.String)` instead.

      Overrides:
        `getZclass` in class `HtmlBasedComponent`
      See Also:
        `HtmlBasedComponent.getSclass()`
