What is the correct way to determine if popup menu belonging to a Tk::Text widget is onscreen? "-postcommand"-option works when menu is displayed, but since there is no "unpostcommand" it doesn't help much..

Sample code:

    use strict;
    use Tk;
        
    my $mw = MainWindow->new();
    my $Text = $mw->Text()->pack;
    my $TextMenu = $Text->menu();
    my $timer = $mw->repeat(100,\&Loop);
    MainLoop;

sub Loop {
        #Try various ways to detect if PopUp-menu of Tk::Text is displ
+ayed..
        #Dont't work (no change when popup is displayed)
    my $IsMenuMapped = $TextMenu->ismapped();
        #Dont't work (no change when popup is displayed)
    my $IsMenuViewable = $TextMenu->viewable();
        #Dont't work (no change when popup is displayed)
    my $WhoGotFocus  = $mw->focusCurrent();
        #Dont't work (no change when popup is displayed)
    my $MenuRootY = $TextMenu->y;
        #Dont't work (no change when popup is displayed)
    my $MenuHeight = $TextMenu->height();    
}
