问题 I have two JFormattedTextField objects on my JFrame object. I want a basic Math (addition) by the values of these JFormattedTextField objects. I want it happen when focus lost either the first or the second textfield. But when " focusLost() ", event doesn't get the last value, it gets the previous value. For example; tf1 has 0 and tf2 has 0 at first. I write 2 to tf1 , and when focusLost() , result ( tf1+tf2 ) become still 0. when I change any of them, the result becomes 2 (the previous value

JFormattedTextField : input time duration value

由 夙愿已清 提交于 2019-11-26 12:31:58
I want to use a JFormattedTextField to allow the user to input time duration values into a form. Sample valid values are: 2h 30m 72h 15m 6h 0h However I am having limited success with this. Can some one please suggest how this can be accomplished? I am OK if this result can be achieved using a JTextField as well. Thanks! If it is worth anything, here's my current attempt: mFormattedText.setFormatterFactory( new DefaultFormatterFactory( new DateFormatter( new SimpleDateFormat("H mm")))); This sorta works except that: I cannot get h and m to appear as plain text (I tried escaping) * The number
