When I run the following, I noticed spacing between nodes; My research revealed that - 1) If I do not add any text to win1 via setwininfo, then there is no problem. 2) When I include this code in a larger app, and when a button click is reveived from some where else, mysteriously the spacing gets corrected. 3) I tried binding the win1 & win2 nodes to content of scene - but no luck.

def mainframew : Integer = 250; def mainframeh : Integer = 500;

class CtrlWindow extends CustomNode {

var wininfo : String;
var fsize : Integer;
var width : Integer;

public function setWinInfo(info : String) {
    wininfo = info;
}

override protected function create () : Node {
    var win = Group {
                                    content: [
                                         VBox {
                                                content: [
                                                    Text {
                                                            font : Font {
                                                                    size: fsize
                                                            }

                                                            content : bind wininfo

                                                            textAlignment : TextAlignment.CENTER  // did not work
                                                    }
                                                ]
                                        }

                                        Rectangle {
                                                width: width, height: 25
                                                fill: Color.TRANSPARENT
                                                strokeWidth : 2
                                                stroke : Color.SILVER
                                        }

                                    ]
                            }

    return win;
}

}

public function run(args : String[]) {

var win1 = CtrlWindow{fsize:14, width:mainframew}; var win2 = CtrlWindow{fsize:14, width:mainframew};

win1.setWinInfo("The spacing between these nodes"); win2.setWinInfo("corrects itself after receiving an event");
