This article was previously published under Q191128 SYMPTOMS
CListCtrl member functions GetItem and SetItem lack an Indent parameter.
CAUSE
The LVITEM structure was modified with version 4.70 of ComCtrl32.dll to
include an indent parameter. This parameter specifies how many image widths
to indent an item. However, there is no place to specify this parameter in
the form of the CListCtrl member function SetItem that takes a list view
item's attributes.
RESOLUTION
You can set the value of the iIndent member of the LVITEM structure by
using the form of the CListCtrl member function SetItem that accepts a
pointer to a LV_ITEM structure. For example:
void CMyCListCtrl::SetItemIndent( int nItem, int nIndent )
{
LV_ITEM lvi;
lvi.iItem = nItem;
lvi.iSubItem = 0;
lvi.mask = LVIF_INDENT;
lvi.iIndent = nIndent;
VERIFY( SetItem( &lvi ) );
}
Likewise, to obtain the indentation of an item in a CListCtrl, use the form
of the CListCtrl member function GetItem that accepts a pointer to a
LV_ITEM structure:
int CMyCListCtrl::GetItemIndent( int nItem )
{
LV_ITEM lvi;
lvi.iItem = nItem;
lvi.iSubItem = 0;
lvi.mask = LVIF_INDENT;
VERIFY( GetItem( &lvi ) );
return lvi.iIndent;
}
Note that because iIndent specifies the number of image widths to indent
the item, you must associate an image list of small images with the items.
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products
listed at the beginning of this article.
MORE INFORMATION
CListCtrl::SetItem has two forms: one that takes a pointer to an LV_ITEM
structure and one that takes individual parameters. The second form does
not have a parameter representing the number of image widths to indent an
item.
