mmi培訓(xùn)資料自定義模板

1、mtk平臺(tái)mmi培訓(xùn)資料(中文)2008-06-06 21:48本文詳細(xì)說(shuō)明了如何建設(shè)一個(gè)自定義列表窗體模板。原理部分請(qǐng)參見MTK平臺(tái)(1)如何添加一個(gè)窗體模板。最終實(shí)現(xiàn)的是一個(gè)字典輸入界面。 布局為：該模板不包含業(yè)務(wù)邏輯，僅提供頁(yè)面 顯示和InputBox框輸入事件后的ListBox的Redraw事件的注冊(cè)，以及基本的輸 入法設(shè)置、清空后的返回函數(shù)。一、添加用戶自定義列表模板的過(guò)程(一) 在 g_categories_controls_map中加入：,MMI_CATEGORY_CUSTOM_LIST,(U8*)custom_defi ne_list,(s16*)coordi nate_c u
