Why don't you just use the /HOURGLASS keyword to show
the user the system is busy?

Construct the widget-tree on a event-handler (if 'program condition' is a
event), or whenever the 'program condition' is true

; Use the keyword /FLOATING in the top-level base, together with the
GROUP_LEADER=widgetID, where widgetID is the id of a widget you want the
widget to be in front of.
3.) No user interaction can take place with the widget or with the remaining
widgets of the program
; Use the /MODAL keyword in the top-level base of your new tree, or use the
SENSITIVE=0 keyword with WIDGET_CONTROL to de-sensitize any widget tree you
don't want user interacting with

Use WIDGET_CONTROL, ev.id, TIMER=periodOfTime, where ev.id can be any
widget; and in the event-handler routine destroy the widget tree when the
TIMER event is received (if you had used SENSITIVE=0 don't forget to make
/SENSITIVE to the widgets before destroying your new tree)

A top-level floating modal widget_base with nothing but a label, which
simply blocks for some period of time would seem to do the trick.
I tried something like:
pro MyApp_event, ev
warn,ev.top
end
pro warn, leader
b=widget_base(GROUP_LEADER=leader,/FLOATING,/MODAL,/COLUMN)
lab=widget_label(b,value=" Please Wait 10 Seconds ")
widget_control, b,/realize
wait,10
widget_control, b,/destroy
end
pro testtlb
app=widget_base(/ROW)
lab=widget_label(app,value='The application')
b=widget_button(app,value='Take Input')
widget_control, app,/REALIZE
XManager, 'MyApp',app,/NO_BLOCK
end
which seemed to do what you want. For some reason on my Linux vs.
5.2.1, it takes a moment for the warning text to appear after the base
is realized.
