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.
