Realizing a widget only once [message #39017]

Is there any possibility to open and realize a widget only once, even
it is called several times? The widget is mainly a draw widget for
images and is called from an other program or widget like this:

DISPLAYIMAGE, Image = Image

The first call, or if there is no such widget present, should really
realize the widget. The second call should not realize a second
widget, but only put the new data (image) to the draw widget.
I think the /OVERPLOT keyword for IIMAGE does equivalently what I
want, but I can`t follow the itools syntax for this feature.

Thank you for every input,
Helmut Ahammer
