Параметры

pItem
Pointer to an LVITEM structure that specifies the item's attributes, as described in the Windows SDK.
nItem
Index of the item to be inserted.
lpszItem
Address of a string containing the item's label, or LPSTR_TEXTCALLBACK if the item is a callback item. For information on callback items, see CListCtrl::GetCallbackMask.
nImage
Index of the item's image, or I_IMAGECALLBACK if the item is a callback item. For information on callback items, see CListCtrl::GetCallbackMask.
nMask
The nMask parameter specifies which item attributes passed as parameters are valid. It can be one or more of the mask values described in LVITEM Structure in the Windows SDK. The valid values can be combined with the bitwise OR operator.
nState
Indicates the item's state, state image, and overlay image. See the Windows SDK topics LVITEM Structure for more information and List-View Item States for a list of valid flags.
nStateMask
Indicates which bits of the state member will be retrieved or modified. See LVITEM Structure in the Windows SDK for more information.
lParam
A 32-bit application-specific value associated with the item. If this parameter is specified, you must set the nMask attribute LVIF_PARAM.

Возвращаемое значение

The index of the new item if successful or -1 otherwise.

Заметки

Calling this method may cause the LVM_INSERTITEM message to be sent to your control window. The associated message handler for the control may fail to set the item text under certain conditions (such as using window styles such as LVS_OWNERDRAW). For more information on these conditions, refer to LVM_INSERTITEM in the Windows SDK.

Пример

CString strText;
int nColumnCount = m_myListCtrl.GetHeaderCtrl()->GetItemCount();

// Insert 10 items in the list view control.
for (int i = 0; i < 10; i++)
{
   strText.Format(TEXT("item %d"), i);

   // Insert the item, select every other item.
   m_myListCtrl.InsertItem(LVIF_TEXT | LVIF_STATE, i, strText, 
      (i % 2) == 0 ? LVIS_SELECTED : 0, LVIS_SELECTED, 0, 0);

   // Initialize the text of the subitems.
   for (int j = 1; j < nColumnCount; j++)
   {
      strText.Format(TEXT("sub-item %d %d"), i, j);
      m_myListCtrl.SetItemText(i, j, strText);
   }
}
