Changing colors - alarm

["De Winne, Joris" <jo...@barco.com>]

Hello,

Is there a good example on how to use the UpdateManager and the
UpdateRunnableQueue? What I'm trying to do is the following:
I've a rectangle that is having a stroke (border). Every second I want to
change the color of that stroke, without clicking or moving over the
rectangle.

This is the code I'm using for the moment, whithout any result:

public void gvtRenderingCompleted(GVTTreeRendererEvent evt) {
            UpdateManager um = SVGViewerImpl.component.getUpdateManager();
            int i = 0;

            while (i < 9) {
                try {
                    i++;
                    if (um.getUpdateRunnableQueue() != null) {
                        um.getUpdateRunnableQueue().invokeAndWait(new
Runnable() {
                            public void run() {
                                // Insert some actions on the DOM here
                                node.setAttributeNS(null,
SVGConstants.SVG_STROKE_ATTRIBUTE, strokeColor);
                            }
                        });
                    }
                    Thread.sleep(1000);
                    System.out.println("Changed color: " + strokeColor);
                    if (um.getUpdateRunnableQueue() != null) {
                        um.getUpdateRunnableQueue().invokeAndWait(new
Runnable() {
                            public void run() {
                                // Insert some actions on the DOM here
                                node.setAttributeNS(null,
SVGConstants.SVG_STROKE_ATTRIBUTE, alarmColor);
                            }
                        });
                    }

                    Thread.sleep(1000);
                    System.out.println("Changed color: " + alarmColor);

                } catch (InterruptedException exp) {
                    exp.printStackTrace();
                }
            }
            System.out.println("End changing color");
        }
    }

The only color I see is the strokeColor, never the alarmColor. Any help is
welcome!
