Does a widget exist?

[Eric Depagne <edepagne eso org>]

Hi all once again.

Does a simple way exist to know if a widget has already been created?

I ihave this small piece of code :

	if (($pos > $Noninteractive)) {
		my $frame_label =  new Gtk::Frame("File Name");
		my $pgplot_file_name = new Gtk::Entry();
		$frame_label->show();
		$frame_label->add($pgplot_file_name);
		$pgplot_file_name->show();
		$hbox_pg1->pack_start($frame_label,$true, $true, 10); 
		print "Non Interactive\n";
	}

which creates a frame with an entry inside every time  $pos > $Noninteractive 
.
As this test can be exectuted as many time as the user wants, I would like 
that if one frame already exist ( created by a prvious positive test) it is 
destroyed before a new one is created.

How can i do that?
Thanks.

Éric.
