Set focus on a cell

I wrote a small piece of code that would help select individual cells in a CListCtrl. This is not supported currently by the MFC.

When the user clicks on the cell in the CListCtrl it draws a rect. around that cell indicating that is the cell selected by the user. This might not be the best solution but a work around if anyone would like to use this.

//Individual cell selection in CLIstCtrl
CListCtrl::OnClick(...)
{
    int column;
    CRect m_rect;
    //the function below is provided in CListCtrl inPlace editing
    int index = GetRowColumnIndex(point, &column);
    if(index == -1)return;
    int offset = 0;
    for(int i = 0; i < column; i++)
      offset += GetColumnWidth(i);
    //Get the rectangle of the label and the icon
    GetItemRect(index, &m_rect, LVIR_BOUNDS);
    m_rect.left += offset + 4;
    //Get the columnWidth of the selected column
    m_rect.right = m_rect.left + GetColumnWidth(column);
    Update(index);
    CClientDC dc(this);    //this is the pointer of the current view
    dc.DrawFocusRect(m_rect);
}

    There's no such function inside CListCtrl. Could you post the code if it's your custom function also?

    Your code is interesting but if you can provide code to select (the way items are selected) and deselct randomly clicked subitems, then it would be very good.

    Thanks in advance.
