Freeform query - How to get clicked column index?

I'm currently creating a report program with a freeform query.

Some users requested about the possibility of sorting by any of these columns. This part itself is done, and it´s working.

My question is:

Using the BROWSE br:CURRENT-COLUMN, how can I get the index to use into SET-SORT-ARROW()?

This is my working code:

DO:

    DEFINE VARIABLE hCol    AS HANDLE.
    DEFINE VARIABLE qh      AS HANDLE.

    IF cBrowserSort = "" THEN 
        cBrowserSort = "DESCENDING" .
    ELSE 
        cBrowserSort = "".

    ASSIGN hCol = BROWSE br:CURRENT-COLUMN
           qh   = QUERY  br:HANDLE
           cBy  = "by temp" + STRING(hCol:NAME).

    qh:QUERY-PREPARE("FOR EACH TT-Component NO-LOCK BY " + hCol:NAME + " " + cBrowserSort + ":").
    qh:QUERY-OPEN().
            
    br:CLEAR-SORT-ARROWS().
    
    //br:SET-SORT-ARROW(hCol:NAME, cBrowserSort EQ "").
        
END.

You need to loop through the browse columns to find the column whose widget handle matches the column you need.

def var hBrowse as handle  no-undo.
def var lFound  as logical no-undo.
def var ix      as integer no-undo.

hBrowse = browse br:handle.

do ix = 1 to hBrowse:num-columns while not lFound:

    if hBrowse:get-browse-column(ix) = hCol then
        lFound = true.

end.

if lFound then
    hBrowse:set-sort-arrow( ix - 1, cBrowserSort = '' ).
