Thanks very much. I tried the method using a second thread for the unmark-action, which does a good job.

So if your Runnable doesn't finish its run method, it doesn't repaint, hence your behavior. You have to invokeLater a Runnable that makes the change, wait 5 seconds in another Thread, and then invokeLater a Runnable that undoes the change. i.e. You could create an inner class and after a selection is made call new MarkerThread().start(); private class MarkerThread extends Thread { public void run() { Runnable runnable; Runnable = new Runnable() { public void run() { // code that changes attributes } } canvas.getUpdateRunnableQueue().invokeLater(runnable); try { Thread.sleep(5000); } catch (InterruptedException ex) {} runnable = new Runnable() { public void run() { // code that undoes the change } } canvas.getUpdateRunnableQueue().invokeLater(runnable); } } -andy -----Original Message----- From: TJ Teegan [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 05, 2005 11:31 AM To: batik-users@xml.apache.org Subject: RE: Update of JSVGCanvas Hello, I am not quite sure if I fully understand the question, so I am just taking a guess here. Hope it helps. You might want to just use the java.util.Timer, or javax.swing.Timer, to count your five seconds. My guess is the canvas does not like it when you put the thread to sleep in PeriodMarker (just a wild guess). Then call your unmark method from within the canvas's update thread. For example: //Some timer event code..... svgCanvas.getUpdateManager().getUpdateRunnableQueue(). invokeLater(new Runnable() { public void run() { maker.unmark(elem); } }); //End timer code Note that in the example above elem, and most likely marker, will have to be declared as final. This should force your updates to show up on the screen instantly. You might also want to call your mark method from within the canvas's update thread similiar to above.
