取得最大最小寬度高度
void InteralMFCWnd::OnGetMinMaxInfo(MINMAXINFO* lpMMI)
{
// TODO: 在此添加消息處理程序代碼和/或調用默認值
if(lpMMI->ptMinTrackSize.x < (LONG)(mMinHeight * m_RectRate) || lpMMI->ptMinTrackSize.y < mMinHeight )
{
lpMMI->ptMinTrackSize.x = (LONG)(mMinHeight * m_RectRate);
lpMMI->ptMinTrackSize.y = mMinHeight;
}
}
窗口大小調整
void InteralMFCWnd::OnSizing(UINT fwSide, LPRECT pRect)
{
CWnd::OnSizing(fwSide, pRect);
if(pRect)
{
int nWidth = pRect->right - pRect->left;
int nHeight = pRect->bottom - pRect->top;
if(m_RectWidnow.width() != nWidth) // 寬度改變
{
pRect->bottom = (LONG)(pRect->top + nWidth / m_RectRate);
}
else if(m_RectWidnow.height() != nHeight) // 高度改變
{
pRect->right = (LONG)(pRect->left + nHeight * m_RectRate);
}
m_RectWidnow.left = pRect->left;
m_RectWidnow.right = pRect->right;
m_RectWidnow.top = pRect->top;
m_RectWidnow.bottom = pRect->bottom;
}
