【代码六】
void CQQHideWndDlg::DoShow()
{
if(m_hideMode == HM_NONE)
return;
CRect tRect;
GetWindowRect(tRect);
INT height = tRect.Height();
INT width = tRect.Width();
INT steps = 0;
switch(m_hideMode)
{
case HM_TOP:
steps = height/HS_STEPS;
tRect.top += steps;
if(tRect.top >= -m_edgeHeight)
{ //你可以把下面一句替换上面的 +=|-=steps 达到取消抽屉效果
//更好的办法是添加个BOOL值来控制,其他case同样.
tRect.top = -m_edgeHeight;
m_hsFinished = TRUE; //完成显示过程
}
tRect.bottom = tRect.top + height;
break;
case HM_BOTTOM:
steps = height/HS_STEPS;
tRect.top -= steps;
if(tRect.top <= (GetSystemMetrics(SM_CYSCREEN) - height))
{
tRect.top = GetSystemMetrics(SM_CYSCREEN) - height;
m_hsFinished = TRUE;
}
tRect.bottom = tRect.top + height;
break;
case HM_LEFT:
steps = width/HS_STEPS;
tRect.right += steps;
if(tRect.right >= width)
{
tRect.right = width;
m_hsFinished = TRUE;
}
tRect.left = tRect.right - width;

break;
case HM_RIGHT:
steps = width/HS_STEPS;
tRect.left -= steps;
if(tRect.left <= (GetSystemMetrics(SM_CXSCREEN) - width))
{
tRect.left = GetSystemMetrics(SM_CXSCREEN) - width;

}
SetWindowPos(&wndTopMost,tRect);
}
BOOL CQQHideWndDlg::SetWindowPos(const CWnd* pWndInsertAfter, LPCRECT pCRect, UINT nFlags)
{
return CDialog::SetWindowPos(pWndInsertAfter,pCRect->left, pCRect->top,
pCRect->right - pCRect->left, pCRect->bottom - pCRect->top, nFlags);
}
到此，程序终于完成了。在我的源代码中还有对WM_SIZING的处理和定义了与之相关的宏，这些主要是控制窗口在调整大小时不能超过最小的宽度和高度，与QQ的自动伸缩无关，所以不在这里提及了。
三、结束语
虽然还不能算是完美的模仿，但效果已经非常非常的接近了。也许有人会奇怪为什么要用Tool Window 风格，这是因为，这样在任务栏中不会显示窗口。从QQ的标题栏高度也可以判断出他也是这种风格，但这样一来就不能拥有最小化、最大化按键了。实际上QQ的最大化、最小化和关闭按键都是
