DM_CUSTOM_DEFINE_INPUTBOX, 需要定义 DM_CUSTOM_DEFINE_LIST 需要定义
};

（二）在dm_get_coordinates（）函数中加入： //设定列表位置和大小（不要忘记全局变量 MMI_custom_Listbox_x 等的定义）
else if( *UICtrlAccessPtr_p == DM_CUSTOM_DEFINE_LIST ) { dm_coordinate_info->s16X = MMI_custom_Listbox_x; dm_coordinate_info->s16Y = MMI_custom_Listbox_y; dm_coordinate_info>s16Width = MMI_custom_Listbox_width; dm_coordinate_info>s16Height = MMI_custom_Listbox_height; dm_coordinate_info->Flags = DM_NO_FLAGS; UICtrlAccessPtr_p ++ ; }
本文详细说明了如何建设一个自定义列表窗体模板。原理部分请参见 《MTK平台(1)——如何添加一个窗体模板》。 最终实现的是一个字典输入界面。布局为：
ห้องสมุดไป่ตู้
该模板不包含业务逻辑，仅提供页面显示和InputBox框输入事件后的 ListBox的Redraw事件的注册，以及基本的输入法设置、清空后的返回 函数。
//设定输入框位置和大小
else if( *UICtrlAccessPtr_p == DM_CUSTOM_DEFINE_INPUTBOX ) { dm_coordinate_info->s16X = MMI_custom_inputbox_x ; dm_coordinate_info->s16Y =
{
fixed_list_goto_item_no_redraw(MMI_fixed_list_menu.highlighted_item } else { fixed_list_goto_item_no_redraw(highlighted_item); } //Create Inputbox memset(custom_single_input_buffer,0,100); pfnUnicodeStrcpy(custom_single_input_buffer,L"Custom Category"); wgui_setup_singleline_inputbox( 0, 0, 240, 320, custom_single_input_buffer, pfnUnicodeStrlen(custom_single_input_buffer), MMI_CATEGORY_CUSTOM_LIST, get_string(right_softkey), get_image(right_softkey_icon), INPUT_TYPE_ALPHANUMERIC_LOWERCASE| INPUT_TYPE_USE_ONLY_ENGLISH_MODES, history_buffer, 0); register_hide_multitap(wgui_hide_multitap); gdi_layer_unlock_frame_buffer(); ExitCategoryFunction = ExitCategoryCustomListScreen; dm_setup_category_functions(dm_redraw_category_screen, dm_get_category_history, dm_get_category_history_size); dm_data.s32ScrId = (S32) GetActiveScreenId();
（三）在Wgui_category.c中定义模板显示函数
void ShowCategoryCustomListScreen( U8 *title, U16 title_icon, U16 left_softkey, U16 left_softkey_icon, U16 right_softkey, U16 right_softkey_icon, S32 number_of_items, U8 **list_of_items, U16 *list_of_icons, S32 flags, S32 highlighted_item, U8 *history_buffer) { /*---------------------------------------------------------------*/ /* Local Variables */ /*---------------------------------------------------------------*/ dm_data_struct dm_data; S32 i; U8 h_flag; /*---------------------------------------------------------------*/
一、添加用户自定义列表模板的过程 （一）在g_categories_controls_map[]中加入：
,{MMI_CATEGORY_CUSTOM_LIST,(U8*)custom_define_list, (s16*)coordinate_custom_list,NULL} const U8 custom_define_list[]= { 5, DM_BASE_LAYER_START, DM_SCR_BG, DM_BASE_CONTROL_SET1, DM_SINGLELINE_INPUTBOX1, DM_LIST1 }; const S16 coordinate_custom_list[]= { DM_FULL_SCREEN_COORDINATE_FLAG,
dm_data.s32CatId = MMI_CATEGORY_CUSTOM_LIST;
//不要忘记该常量 MMI_CATEGORY_CUSTOM_LIST的定义
dm_data.s32flags |= DM_CLEAR_SCREEN_BACKGROUND; //dm_data.s32flags |= DM_SHOW_VKPAD; dm_register_vkpad_callback(CustomList_virtual_keypad_callback); dm_setup_data(&dm_data); dm_redraw_category_screen(); } /* end of ShowCategory353Screen */ void CustomList_virtual_keypad_callback(void) { #if defined(__MMI_TOUCH_SCREEN__) mmi_pen_editor_clear_and_show_virtual_keyboard_area(); #endif
