m_p1.MoveWindow(rect);
m_p2.MoveWindow(rect);
m_p3.MoveWindow(rect);
return TRUE; // 除非将焦点设置到控件,否则返回 TRUE
}
当选择不同的标签时对不同的窗口进行隐藏或者显示
void CMainDlg::OnSelchangeTab(NMHDR* pNMHDR, LRESULT* pResult)
{
*pResult = 0;
int nIndex = m_tab.GetCurSel();
int nCount = m_tab.GetItemCount();
CWnd* ps[] = { &m_p1,&m_p2,&m_p3 };
int i = -1;
while (++i<nCount)
{
if (nIndex == i)
ps[i]->ShowWindow(SW_SHOW);
else
ps[i]->ShowWindow(SW_HIDE);
}
}
