【正文】 _name,U32 max_msg_size,U32 max_msgs) ? Write To Queue – OSLSTATUS OslIntWriteMsgQ(oslMsgqid msgqid,void *msgPtr,U32 msgSize, OSLWAITMODE wait_mode) ? Read From Queue – OSLSTATUS OslIntReadMsgQ(oslMsgqid msgqid,void *msgPtr, U32 *msgSize,OSLWAITMODE wait_mode) Timer API ? Timer API – Start a timer ? StartTimer(U16 timerid, U32 delay, FuncPtr funcPtr) – Stop a timer ? StopTimer(U16 timerid) OSL ? Subtle features of OSL – Skin is loaded as bitmap. – Button coordinates and Press Event (Up or Down) are calculated and passed to KBD task. – Keyboard interface to test the functionality UI Layer ? UI Layer – Category Functions ? ? The category layer consists of a set of functions that an application can use to define its User Interface. ? ? Each Category screen contains the following functions: – Function to enter (display) – Function to exit – Function to get the size of History – Function to get the History DEBUG 調(diào)試 Debugging Support ? Debug Levels – Debug window is associated with simulator on PC version – API provided for writing debug messages to file – Various debug levels are present ? DEBUG_FATAL ? DEBUG_ERROR ? DEBUG_INFORMATION ? DEBUG_DUMP ? DEBUG_TEMPORARY – Debug Macros ? PRINT_FATAL (args) ? PRINT_ERROR (args) ? PRINT_INFORMATION (args) ? PRINT_DUMP (args) ? PRINT_TEMPORARY (args) Debugging Support ? Examples – PRINT_TEMPORARY((File: [%s] Line: [%d] KBD \n,__FILE__,__LINE__))。 Protocol Events （協(xié)議事件） 187。Messages in this queue are put by the Protocol Stack. – Framework Layer 處理事件 . – Framework Layer 通過(guò)回調(diào)回到應(yīng)用層 – Application layer 使用 UI Layer category functions 和 themes 做屏幕顯示。 ? L4 / NS Queue : – The MMI task 將 MMI 的事件寫入 L4 / NS Queue ， L4 task / Network Simulator從 L4 / NS Queue中讀取消息 . 任務(wù)結(jié)構(gòu) 詳解 （續(xù)） 。 代碼結(jié)構(gòu)和導(dǎo)航 ? Inc：包含頭文件對(duì)所有應(yīng)用 include 頭文件和宏定義 ? MiscFramework :the Pixtel MMI platform 管理字體和支持 Unicode …
