I have the following child window initialization code.

    my $Child = $Window->{Client}->AddMDIChild (
      -name         => "Child".$ChildCount++,
      -title => $title,
      -onResize => \&ChildSize,
    ) or die "Child";

    $Child->AddGrid (
        -name    => "Grid",
        -pos     => [0, 0],
        -rows    => 50,
        -columns => 10,
        -fixedrows    => 1,
        -fixedcolumns => 1,
        -editable => 1,
    ) or die "new Grid";

Now I want to be able to write some information to a database when a cell is edited in my grid control.

sub Grid_EndEdit {
    my ($row, $col) = @_;
    my $string=$Grid->GetCellText($row, $col);
    my $changeid=$Grid->GetCellText($row, 1);
    my $changeattribute=$Grid->GetCellText(0, $col);
    $dbh->do("UPDATE INV SET $changeattribute = ? WHERE CODE = ?" , un
+def, $string, $changeid);
}

I cant use the previous function because I don't know the handle to the childwindow. Is there a way for me to determine this without passing the handle myself. Which I can't do anyway since _EndEdit is a function of WIN32::GUI::Grid.pm.
