CListCtrl::GetNextSelectedItem
Gets the index of the list item identified by pos, then sets pos to the POSITION value.
int GetNextSelectedItem(
POSITION& pos
) const;
Parameters
- pos
A reference to a POSITION value returned by a previous call to GetNextSelectedItem or GetFirstSelectedItemPosition. The value is updated to the next position by this call.
Return Value
The index of the list item identified by pos.
Remarks
You can use GetNextSelectedItem in a forward iteration loop if you establish the initial position with a call to GetFirstSelectedItemPosition.
You must ensure that your POSITION value is valid. If it is invalid, then the Debug version of the Microsoft Foundation Class Library asserts.
Example
The following code sample demonstrates the usage of this function.
POSITION pos = m_myListCtrl.GetFirstSelectedItemPosition();
if (pos == NULL)
{
TRACE(_T("No items were selected!\n"));
}
else
{
while (pos)
{
int nItem = m_myListCtrl.GetNextSelectedItem(pos);
TRACE(_T("Item %d was selected!\n"), nItem);
// you could do your own processing on nItem here
}
}
