Well, don't create new widgets when you click the buttons.
Just get the text out of the one text widget you have, change
it, and put it back. Your event handler should look like this:
pro widget_linking_pointers_event,ev
widget_control,ev.top,get_uvalue = pstate
widget_control,ev.id,get_uvalue = uval
case uval of
'Lower' : begin
print,'hello'
widget_control,(*pstate).text, get_value = name
widget_control,(*pstate).text, set_value = StrLowCase(name)
end
'Upper' : begin
widget_control,(*pstate).text,get_value = name
widget_control,(*pstate).text,set_value = StrUpCase(name)
end
endcase
end
Cheers,
David
