64 * @brief This class is an implementation of a %Footer control.
68 * The %Footer class displays a multi-purpose area at the bottom of the screen. It is used to switch between different application
69 * "views", or to host buttons for performing user-defined actions.
71 * For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/ui/implementing_footer.htm">Footer</a>.
73 * The following examples demonstrate how to use the %Footer class.
74 * - Constructing a footer
75 * When creating a %Form, specify the FORM_STYLE_FOOTER parameter in the Form::Construct() method.
80 * TestForm::Initialize(void)
82 * Construct(FORM_STYLE_NORMAL | FORM_STYLE_INDICATOR | FORM_STYLE_FOOTER);
87 * Gets the footer with the GetFooter() method, and sets the footer style
91 * TestForm::Initialize(void)
93 * Footer* pFooter = GetFooter();
94 * pFooter->SetStyle(FOOTER_STYLE_SEGMENTED_TEXT);
98 * - Adding items to the footer:
99 * Adds FooterItems or ButtonItems according to the footer style. The action ID registered in the Construct() method is notified
100 * when items are touched.
104 * TestForm::Initialize(void)
106 * FooterItem footerItem;
107 * footerItem.Construct(ID_FOOTER_ITEM);
108 * footerItem.SetText("FooterItem");
110 * pFooter->AddItem(footerItem);
112 * ButtonItem buttonItem;
113 * buttonItem.Construct(BUTTON_ITEM_STYLE_ICON, ID_HEADER_BUTTON);
114 * buttonItem.SetIcon(BUTTON_ITEM_STATUS_NORMAL, __pBitmap);
116 * pFooter->SetButton(BUTTON_POSITION_LEFT, buttonItem);
121 * -Using the back button
122 * The image of back button is internally set by UI framework.
126 * TestForm::Initialize(void)
128 * pFooter->SetBackButton();
