Example
The following code example defines the variable, m_headerCtrl, that is used to access the current header control. This variable is used in the next example.
CHeaderCtrl m_headerCtrl;
CSplitButton m_splitButton;
The following code example demonstrates the SetFocusedItem and GetFocusedItem methods. In an earlier section of the code, we created a header control with five columns. However, you can drag a column separator so that the column is not visible. The following example sets and then confirms the last column header as the focus item.
void CNVC_MFC_CHeaderCtrl_s4Dlg::OnXSetfocuseditem()
{
if (controlCreated == FALSE) {
MessageBox(_T("Header control has not been created yet."));
return;
}
// Check that we get the value we set.
int item = m_headerCtrl.GetItemCount() - 1;
m_headerCtrl.SetFocusedItem(item);
int itemGet = m_headerCtrl.GetFocusedItem();
CString str = _T("Set: focused item = %d\nGet: focused item = %d");
str.Format(str, item, itemGet);
MessageBox(str, _T("Set/GetFocused Item"));
}
