Question

I am using editwinpath, which returns currently editing window path, but how to know which cell is currently editing? Has tablelist any function for it?

Answer 1

According to the documentation, you can register an -editstartcommand callback which will let you intercept the behavior so you can store the cell:

proc editStarted {widget row column initialText} {
    global cell
    set cell $row,$column
    return $initialText
}
$yourTablelistInstance configure -editstartcommand editStarted

If you need to also know when nothing is being edited, a similar -editendcommand option exists.
