If you're still about Zentara, I have the below rectange's size variable, working to create a rectangle:

$o1 = 0;
$d1 = -60;
$o2 = 250;
$d2 = -58;
$size =   [[$o1, $d1], [$o2, $d2]];

$menubox = $zinc->add('rectangle',$menugroup,
                # -size =>
                  $size,          #  [[0, -60], [250, -58] ]       #le
+ft/right down/up left/right down/up
                 -filled => 1,
                  -fillcolor => $gradset{'roundrect4ed'},
                 -linewidth => 0,
                # -linecolor => '#000000',
                 -priority => 1,
                 -tags => ['menu'],
                # -visible => 1,
                  );

### I am using this next bit to slide it open and am also trying to en
+large the rectangle at the same time

 sub Slide_open{
        $zinc->itemconfigure($menubox, -visible=> 1);
       # $zinc->itemconfigure($ejecttext, -visible=> 0);  #
       # $zinc->itemconfigure($menuitems1, -visible=> 1);  #
        #$zinc->itemconfigure($textoptions3, -visible=> 1);  #
        
     my $count = 0;
     my $repeater;
     $repeater = $mw->repeat(25, sub{
              $zinc->translate($menugroup, 0 , -3 );     # move
          $count++;
             if($count >= 37){ $repeater->cancel }
      } );
$zinc->bind($ejecttext, '<Enter>', \&Slide_close); # for same thing to
+ be used to close the above.


# here is where I'm trying to resize the rectange, but as you may see,
+ I'm stuck...
$d2 = $d2+3;
$size = [[$o1, $d1], [$o2, $d2]]; #
$zinc->itemconfigure($menubox,  -\$size => $size);  #  what do I switc
+h "-\$size" with/for

#$mw->update;
   }

I normally "$zinc->itemconfigure($menubox, -visible => 1);" as it were, using a "-visible => somthing(0 or 1)", but $size has no "-visible" as it were, before it? If you get what I mean.

I'll say that again another way. How do I itemconfigure $menubox's $size, when it doesn't have a -visible, -linecolor, -filled or something, in front of it .
