api listview - finding subitem clicked

I've got a listview using no column header, report, single select, and full row select styles. The column data is occupied by a single character and is 20px wide; each row can contain similar values, so searching for a specified value isn't feasible.

Is there a function to determine which subitem a user has clicked on? I can find the selected row, but I'm just not sure how I'd go about finding the column. ListView_GetSelectedColumn seemed promising, but it always returns 0.

I'm looking to find both the row and col by index pos.

Code:

---

case WM_NOTIFY :

        if(((LPNMHDR)lParam)->code == NM_CLICK) {
               
                int index = SendMessage(hndListV, LVM_GETNEXTITEM, -1, LVNI_SELECTED);
                // need help finding the subitem
                               
      }

break;

Any ideas would be greatly appreciated.

This might help. As it mentions the structure has members for item, subitem and where the click was. That and/or LVM_SUBITEMHITTEST should get you somewhere.

Thank you for the reply; I sure appreciate your time.

I tried it out but couldn't get what I was looking for. I'm still trying to learn the basics, so I probably goofed it up somewhere. I did come up with something using a chimp approach that *appears* to work.

Code:

---

if(((LPNMHDR)lParam)->code == NM_CLICK) {
                               
    int index = SendMessage(hndListV, LVM_GETNEXTITEM, -1, LVNI_SELECTED);
    POINT pt = { 0 };
    LVITEM lvi;

    GetCursorPos(&pt);
    ScreenToClient(hndListV, &pt);

    ZeroMemory(&lvi, sizeof(LVITEM));

    lvi.iItem = index;     
    lvi.iSubItem = pt.x / 14;  // 14 is the cx member of the LVCOLUMN structure
    ...
}

---

Something like...

Code:

---

NMITEMACTIVATE  NMItem = {0};
int row = -1, column = -1;

if(((LPNMHDR)lParam)->code == NM_CLICK)
{
    NMItem = (LPNMITEMACTIVATE) lParam;
    //row clicked is the item member
    row = NMItem.iItem;
    //column clicked is subitem
    column = NMItem.iSubItem;
}

novacain, thank you immensely; it does exactly what I wanted.
