三、设置项类型

在S60平台有十种不同的设置项类型，下面我们来仔细介绍这些类型及它的资源结构。

3.1 Binary Switch

二进制开关是最简单的设置项类型了，它允许设置成开和关，并且不需要单独的设置页，在设置列表中就可以改变。二进制开关设置项类型返回一个布尔（TBool）型变量在应用程序设置数据中。设置项类中使用的二进制开关类型是CAknBinaryPopupSettingItem。

下面是一个二进制开关资源定义的例子：

RESOURCE AVKON_SETTING_ITEM_LIST r_setting_list_setting_binary { flags= EAknSettingItemNumberedStyle; title = qtn_exsl_outline07; initial_number = 1; items = { AVKON_SETTING_ITEM { identifier = EAknExSettingBinary; setting_page_resource = r_binary_setting _page; associated_resource = r_popup_setting_binary_texts; name = qtn_exsl_binary_title; } }; } RESOURCE AVKON_POPUP_SETTING_TEXTS r_popup_setting_binary_texts { flags = 0; setting_texts_resource = r_on_off_texts; popped_up_texts_resource = r_popped_up_on_off_texts; } RESOURCE ARRAY r_on_off_texts { items = { AVKON_ENUMERATED_TEXT { value=1; text = qtn_exsl_texts_on; }, AVKON_ENUMERATED_TEXT { value=0; text = qtn_exsl_texts_off; } }; } RESOURCE ARRAY r_popped_up_on_off_texts { items = { LBUF { txt = qtn_exsl_texts_enabled; }, LBUF { txt = qtn_exsl_texts_disabled; } }; } RESOURCE AVKON_SETTING_PAGE r_binary_setting_page { number= 0; label= qtn_exsl_binary_title; type = EAknCtPopupSettingList; }  

 

 

 

3.2 Text Editor

文本设置项允许用户输入设置的值。这些设置值存储在用户指定描述符（user-specified descriptor）中。设置项类使用的文本编辑类型是CAknTextSettingItem。

3.3 Enumerated Text

枚举文本设置项为用户提供一个选择列表。它也允许为设置项再输入一个文本值，通过选择弹出菜单的“Other”来完成它。这样实际上就有了三种不同的枚举文本视图：设置列表中包含设置项，设置页显示多种选择，文本编辑器输入非预定义的文本。这些设置值存储在设置项构造的描述符中。设置项类使用枚举文本类型是CAknEnumeratedTextPopupSettingItem。
