Try this...

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
pro ev_handler,event
uname = widget_info(event.id,/uname)
case uname of
'button_1': $
begin
but_b = widget_button(event.top, $
value = 'Now Press Me', $
uname = 'button_2')
end
'button_2': $
begin
widget_control,event.id,/destroy
end
'quit': widget_control,event.top,/destroy
else:
endcase
end
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
pro dynamic_widget
tlb = widget_base(/col,/tlb_frame_attr)
but_a = widget_button(tlb,value = 'Press Me', $
uname = 'button_1')
quit_button = widget_button(tlb,value = 'Quit', $
uname = 'quit')
widget_control,tlb,/realize
xmanager,'dynamic_widget',tlb,/no_block, $
event_handler = 'ev_handler'
end
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

Hope this helps,

Rob
