Question

Does anyone know how to bind a CPen object to a listbox in VS2005 C++?

Can I do it as a ToString with some sort of conversion?

I am creating a custom list of different pens for the user to select.

Thanks.

    COLORREF  rgbRED = (255,0,0);
    CPen penRed(PS_SOLID,3,rgbRED);

    CDialog::OnInitDialog();
    ShowWindow(SW_SHOW);
    UpdateData();
    lbLineWeight.InsertString(penRed);

2 options.

• (simple) Use a normal CListBox with strings as the items, and keep the link between the string to the actual CPen as free functions (or member of some other classes) and you will have to do a one-to-one association between the current selected item (usually an index number) and the CPen information you have.

• (a bit more complex) Derive your own class from CListBox and keep the CPen data internally, you will still have to keep a list of valid CPen in that new class, and do the one-to-one association between the selected item and the actual CPen; as a bonus you can make you derived CListBox owner-drawn and instead of using string, you could draw some sort of representation of each pen in the list items.

Another tought, you could add the CPen as a user data to each CListBox item (CListBox::SetItemData) to make the link between the item and the actual item a bit more easy.

Good luck.
