If you do this you may end up with dozens of similar

widget windows. What I do to avoid this is to set a

flag in my info structure which shows that the child

widget already exists and it will be destroyed before

the new one is created. It looks like this.

IF (info.wiczoom NE 0l) then WIDGET_CONTROL,info.wiczoom,/DESTROY
zoomBase = WIDGET_BASE(TITLE='WIC Zoom',ROW=3)
info.wiczoom = zoomBase
