At the moment I'm only assigning the dynamically created popup to the image.

Image image = new Image();
Popup popup = new Popup();
image.setTooltip(popup);

Thats all and its working. But if i use, as you suggested, "popup.open" then I'll have to set 2x Listeners or am I missing something?

Image image = new Image();
Popup popup = new Popup();
popup.addEventListener(Events.ON_MOUSE_OUT, myPopupOpenListener);
popup.addEventListener(Events.ON_MOUSE_OVER, myPopupOpenListener);

...

myPopupOpenListener -> "popup.open(image, "after_pointer");"
