Re: Tablelist visible rows

Does anyone know how to determine the number of visible rows currently
displayed in a Tablelist (or listbox for that matter) ? The -height
option sets the desired height in lines (rows) but does not reflect
the actual number lines on show.

kind regards

Same method for tablelist and listbox widgets:

set topRow [$tbl index @0,0]
set btmRow [$tbl index @0,[winfo height $tbl]]
set visibleCount [expr $btmRow - $topRow + 1]
