CListBox::DeleteItem

Called by the framework when the user deletes an item from an owner-draw CListBox object or destroys the list box.

virtual void DeleteItem( 
   LPDELETEITEMSTRUCT lpDeleteItemStruct  
);

lpDeleteItemStruct

A long pointer to a Windows DELETEITEMSTRUCT structure that contains information about the deleted item.

The default implementation of this function does nothing. Override this function to redraw an owner-draw list box as needed.

See CWnd::OnDeleteItem for a description of the DELETEITEMSTRUCT structure.

// CMyODListBox is my owner-drawn list box derived from CListBox. This  
// example simply frees the item's text. The list box control was created  
// with the following code: 
//   m_myODListBox.Create( 
//      WS_CHILD|WS_VISIBLE|WS_BORDER|WS_HSCROLL|WS_VSCROLL| 
//      LBS_SORT|LBS_MULTIPLESEL|LBS_OWNERDRAWVARIABLE|LBS_WANTKEYBOARDINPUT, 
//      CRect(10,250,200,450), pParentWnd, IDC_MYODLISTBOX); 
// 
void CMyODListBox::DeleteItem(LPDELETEITEMSTRUCT lpDeleteItemStruct)
{
   ASSERT(lpDeleteItemStruct->CtlType == ODT_LISTBOX);
   LPVOID lpszText = (LPVOID) lpDeleteItemStruct->itemData;
   ASSERT(lpszText != NULL);

   free(lpszText);

   CListBox::DeleteItem(lpDeleteItemStruct);
}
