Hi,

I would like to know how can I retrieve the value of the selected item
from the Listbox widget. I tried different options in Listbox widget
(<Double-ButtonPress-1>, <Return>) but I was not able to retrieve the
expected results.
Can anyone let me know how can I do this.

Thanks,
doni

}

sub display_lb_curselection {
my $lbox1 = shift;
my @cs = $lbox1->curselection();
my $selection = $lbox1->selectionSet(@cs);
print "Current choices: ", $selection;
print "\n";
}

I was able to retrieve the value of the item selected from the Listbox
widget using get option.
Can anyone suggest me how can I do multiple selections from Listbox
widget..

Here is the change I made to the above line:
my $selection = $lbox1->get(@cs);
