MTK: ShowCategory200Screen() //电话簿快速查找 收藏

2008-09-01 | MTK: ShowCategory200Screen()
 
说明:

1.所有的ShowScreen都有2个ID:Screen ID(EntryNewScreen()函数中设置的ID),以及模板ID(Category ID)。

2.所有的窗口模板的基本设置都保存在一个全局变量:g_categories_controls_map中。它的结构是:

typedef struct

{

    U16 category_id;                           模板ID号

    U8 *control_set_p;                        这个模板的组件指针

    S16 *default_coordinate_set_p;   这个模板中各组件属性的指针

    S16 *rotated_coordinate_set_p;  其他特殊属性指针

} dm_category_id_control_set_map_struct;

 

例如Category200:{MMI_CATEGORY200_ID, (U8 *) category200, (S16 *) coordinate_set200, NULL},

组件:

const U8 category200[] =

{

    5,

    DM_BASE_LAYER_START,

    DM_SCR_BG,

    DM_BASE_CONTROL_SET1,

    DM_CATEGORY_CONTROLLED_AREA,

    DM_SINGLELINE_INPUTBOX1

};

属性:

const S16 coordinate_set200[] =

{

    DM_FULL_SCREEN_COORDINATE_FLAG,

    DM_CONTENT_COORDINATE_FLAG,

    26,

       MAIN_LCD_DEVICE_HEIGHT - MMI_BUTTON_BAR_HEIGHT - MMI_SINGLELINE_INPUTBOX_HEIGHT - 2,

       MAIN_LCD_DEVICE_WIDTH - 29,

       MMI_SINGLELINE_INPUTBOX_HEIGHT,

       DM_NO_FLAGS

};

 

3.一个Screen ID的属性变量:g_screenid_coordinate_sets_map[]。其中只包含了几个Screen的属性指针,可能是用来设置一些特殊窗口的属性。结构是:

typedef struct

{

    S32 screen_id;

    S16 *coordinate_set_p;

} dm_screen_id_coordinate_set_map_struct;

 

4.2个函数:

(1)U8 *dm_search_control_set(S32 category_id, S16 **default_coordinate_set_p)

       获取某个模板的组件和组件属性指针。

(2)S16 *dm_search_coordinate_set(S32 ScrId)

       获取Screen ID的属性指针。
