2、于”等項 。（2）若單擊“畫圖”菜單項，則繪出P103圖形。若在用戶區(qū)內(nèi)按下鼠標(biāo)左鍵，則動態(tài)創(chuàng)建一個包括“刪除計算總和”、“添加計算平均值”和“修改計算均方差”三個菜單項的彈出式菜單，由此菜單控制“計算”菜單中菜單項刪除、添加與修改。（要求新的彈出式菜單開始時不可用，按下右鍵后變?yōu)榭捎?。?單擊“修改計算均方差”菜單項后，“計算”菜單下的“計算均方差”項改為“線性擬合”，單擊“添加計算平均值”菜單項后，“計算”菜單中添加上了“計算平均值”菜單項 。 （3）將光標(biāo)設(shè)定為自己名字中的某個字、圖標(biāo)設(shè)定為自己名字中的另一個字。 2、應(yīng)用程序中所用到的資源、消息，簡介主要函數(shù)的功能；3、程序?qū)崿F(xiàn) 4、操
