CComboBox::DeleteItem
Called by the framework when the user deletes an item from an owner-draw CComboBox object or destroys the combo box.
virtual void DeleteItem(
LPDELETEITEMSTRUCT lpDeleteItemStruct
);
Parameters
- lpDeleteItemStruct
A long pointer to a Windows DELETEITEMSTRUCT structure that contains information about the deleted item. See CWnd::OnDeleteItem for a description of this structure.
Remarks
The default implementation of this function does nothing. Override this function to redraw the combo box as needed.
Example
// CMyComboBox is my owner-drawn combo box derived from CComboBox. This
// example simply dumps the item's text. The combo box control was
// created with the following code:
// pmyComboBox->Create(
// WS_CHILD|WS_VISIBLE|WS_BORDER|WS_HSCROLL|WS_VSCROLL|
// CBS_SORT|CBS_OWNERDRAWVARIABLE,
// myRect, pParentWnd, 1);
//
void CMyComboBox::DeleteItem(LPDELETEITEMSTRUCT lpDeleteItemStruct)
{
ASSERT(lpDeleteItemStruct->CtlType == ODT_COMBOBOX);
LPTSTR lpszText = (LPTSTR) lpDeleteItemStruct->itemData;
ASSERT(lpszText != NULL);
AFXDUMP(lpszText);
}
