MFC对话框分割条拖动控件，水平垂直任意分隔拖动

1、 分割控件类:CSplitterControl SplitterControl.h SplitterControl.cpp 2、创建对象、增加资源 class xx { ... private: CSplitterControl m_wndSplitter1; // 上下分割 IDC_SPLITTER_TOP 分割线资源更改资源可见属性为不可见，防止出现2条线 void DoResize1(int delta); CSplitterControl m_wndSplitter2; // 左右分割 IDC_SPLITTER_LEFT void DoResize2(int delta); } 3、初始化 BOOL CT1Dlg::OnInitDialog() { ... // TODO: Add extra initialization here {//m_wndSplitter1 CRect rc; CWnd* pWnd; pWnd = GetDlgItem(IDC_SPLITTER_TOP); pWnd->GetWindowRect(rc); ScreenToClient(rc); m_wndSplitter1.Create(WS_CHILD | WS_VISIBLE, rc, this, IDC_SPLITTER_TOP); CRect rc2; GetDlgItem(IDOK)->GetWindowRect(&rc2); ScreenToClient(&rc2); CRect rc3; GetDlgItem(IDCANCEL)->GetWindowRect(&rc3); ScreenToClient(&rc3); m_wndSplitter1.SetRange(rc2.bottom, rc3.top); } {// m_wndSplitter2 CRect rc; CWnd* pWnd; pWnd = GetDlgItem(IDC_SPLITTER_LEFT); pWnd->GetWindowRect(rc); ScreenToClient(rc); m_wndSplitter2.Create(WS_CHILD | WS_VISIBLE, rc, this, IDC_SPLITTER_LEFT); CRect rc2; GetDlgItem(IDC_BUTTON1)->GetWindowRect(&rc2); ScreenToClient(&rc2); CRect rc3; GetDlgItem(IDC_BUTTON2)->GetWindowRect(&rc3); ScreenToClient(&rc3); m_wndSplitter2.SetRange(rc2.right+1, rc3.left-1); } return TRUE; // return TRUE unless you set the focus to a control } LRESULT CT1Dlg::DefWindowProc(UINT message, WPARAM wParam, LPARAM lParam) { // TODO: Add your specialized code here and/or call the base class if (message == WM_NOTIFY) { if (wParam == IDC_SPLITTER_TOP) { SPC_NMHDR* pHdr = (SPC_NMHDR*) lParam; DoResize1(pHdr->delta); } else if (wParam == IDC_SPLITTER_LEFT) { SPC_NMHDR* pHdr = (SPC_NMHDR*) lParam; DoResize2(pHdr->delta); } } return CDialog::DefWindowProc(message, wParam, lParam); } void CT1Dlg::DoResize1(int delta) { CSplitterControl::ChangeHeight(GetDlgItem(IDC_BUTTON1),delta); CSplitterControl::ChangeHeight(GetDlgItem(IDC_BUTTON2), -delta, CW_BOTTOMALIGN); Invalidate();

此代码为MFC中对对话框分割的示例，注意是对话框，不是SDI。
