21.3.6..List Control and Icons........................................................................

A list control can be configured to display pictures that accompany either the columns,

the list items, or both. If you want to display a bitmap on the column, you should declare

and initialize a CImageList variable. Then call the CListCtrl::SetImageList() method

and pass it as argument. If you plan to do this, and if you are using the first version of the

CListCtrl::InsertColumn() method that takes an LVCOLUMN pointer as argument, then

add the LVCF_IMAGE value to the mask variable and add the LVCFMT_IMAGE

value to the fmt variable. To specify the image that will display on the column header,

assign its index to the value of the iImage variable. Here is an example:

BOOL COthersDlg::OnInitDialog()

{

CDialog::OnInitDialog();

// TODO: Add extra initialization here

LVCOLUMN lvColumn;

CImageList *ImgHeaders = new CImageList;

ImgHeaders->Create(16, 16, ILC_MASK, 1, 1);

ImgHeaders->Add(AfxGetApp()->LoadIcon(IDI_UP));

ImgHeaders->Add(AfxGetApp()->LoadIcon(IDI_LOSANGE));

m_List.SetImageList(ImgHeaders, LVSIL_SMALL);

lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH | LVCF_IMAGE;

lvColumn.fmt = LVCFMT_LEFT | LVCFMT_IMAGE;

lvColumn.cx = 120;

lvColumn.pszText = "Full Name";
