A Dual ListBox Selection Manager 示例代码

在 OnInitialUpdate 加入下列代码：

void CDualListDemoView::OnInitialUpdate()
{
 ... // Normal processing
 // ADDED TO DEFAULT THE LISTS.
 // This code will need to be replaced with your
 // application specific  code that knows what belongs
 // in each list.
 m_DualListManager.AddItemToAvailableList(_T("Red"), 0);
 m_DualListManager.AddItemToAvailableList(_T("Green"), 1);
 m_DualListManager.AddItemToAvailableList(_T("Blue"), 2);
 m_DualListManager.AddItemToChoosenList(_T("Yellow"), 3);
 m_DualListManager.AddItemToChoosenList(_T("Purple"), 4);
 m_DualListManager.AddItemToChoosenList(_T("Orange"), 5);

 // ADDED TO INITIALIZE THE MANAGER CLASS
 m_DualListManager.InitializeControls(this,
  IDC_FV_LIST_AVAILABLE,
  IDC_FV_LIST_CHOOSEN,
  IDC_FV_ADD,
  IDC_FV_ADD_ALL,
  IDC_FV_REMOVE,
  IDC_FV_REMOVE_ALL,
  IDC_FV_MOVE_UP,
  IDC_FV_MOVE_DOWN);
}

重载 OnCmdMsg methodm 然后调用在 Dual List Manager Object　中调用 ProcessCmdMsg.

BOOL CDualListDemoView::OnCmdMsg(UINT nID, int nCode,
void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo)
{
 // ADDED TO INTERCEPT MESSAGE THAT THE DUAL
 // LIST MANAGER NEEDS
 m_DualListManager.ProcessCmdMsg(nID, nCode);

 // NOW CALL THE BASE CLASS
 return CFormView::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);
}

加入下列成员到你的　header file.

CDualListManager m_DualListManager;
