收縮模式和位置決定后，剩下的工作就由最后兩個(gè)核心函數(shù)完成了：實(shí)現(xiàn)收縮的DoHide()，實(shí)現(xiàn)伸展的DoShow()。在這兩個(gè)過程中m_hsFinished，m_hiding 這兩個(gè)變量起到很重要的控制作用。由于伸縮過程沒完成時(shí)，hsFinished始終為FALSE，所以Timer 2 不會(huì)關(guān)閉，于是在OnTimer中會(huì)重復(fù)調(diào)用這兩個(gè)函數(shù)之一，在這兩個(gè)函數(shù)體內(nèi)，窗口位置有規(guī)律地遞減或遞增就可以達(dá)到QQ的“抽屜”效果了，有趣的是即使伸縮過程還沒完成，你也可以在這個(gè)過程中改變m_hiding這個(gè)值來決定他是伸還是縮，正如QQ一樣。你可以把Timer 2 的事件間隔調(diào)大一點(diǎn)，然后在窗口伸縮時(shí)，鼠標(biāo)來回地進(jìn)出窗口就會(huì)很容易看到這樣有趣的效果（還沒縮進(jìn)去又被拉了出來，或者還沒拉出來又縮進(jìn)去了）。
