Here's one kludge solution which I use:
1) Give a normally non-event generating widget [e.g. a base or a label --
hereafter called the dummy widget] within the floating widget a UVALUE
(assuming you handle your events by UVALUE).
2) After realizing the floating widget, send a timer event to the dummy
widget with a delay of (say) 2 seconds.
3) In the event handler for you floating widget have the event actio
for the dummy consist of:
widget_control, event.top, /show
widget_control, event.id, timer=2.0
While this won't make it un-hideable, at least it will pop to the front
every 2 seconds.
