Hello everybody,
I try to use Pmw library -> ScrollListBox. If I take the example of
the reference web site (see below, I just quote the minimal code to
launch, I note by <----- the line which are not execute when I click)
It works, except selectioncommand and dblclickcommand: associate
function doesn't run when I click one or two time.
Could you have an idea about that ? Is it about my tried code ?
Thank,
Guilhem
