jformattedtextfield

Supossing that a JFormattedTextField is enabled and contains a formatter, is there a way to make it readonly? With a JTextField , we just need to suply a custom Document and do all the control there, but with a JFormattedTextField I suppose that things are a little more complicated as we don't want to mess with its document filter. I really need this feature. So, is there a way to achieve this? UPDATE: Just my opinion, but it seems that the JFormattedTextField is so bad designed in this sense that it leaves no easy solution to this simple problem. Marcos You can simply use: JFormattedTextField

I have the estimated time the it would take for a particular task in minutes in a float. How can I put this in a JFormattedTextField in the format of HH:mm:ss ? no.good.at.coding JFormattedTextField accepts a Format object - you could thus pass a DateFormat that you get by calling DateFormat#getTimeInstance() . You might also use a SimpleDateFormat with HH:mm:ss as the format string.

I have a JFormattedTextField with a NumberFormat with Locale.US. So the decimal separator is the point and the grouping separator is the comma. Now I type the string "1,23" in this text field and move the focus to another component. I would expect the string to disappear (like it does when i type "a" instead of "1,23") because it is obviously not a valid representation of a number when using Locale.US. But instead the text in the text field is changed to "123". This is because the used NumberFormat is not strict when parsing and simply ignores the comma. Question : How can I tell NumberFormat

I used JFormattedTextField with NumberFormat in this way: -Creat a JFormattedTextField refernce JFormattedTextField integerField; -Create a NumberFormat refernce NumberFormat integerFieldFormatter; -In the constructor: integerFieldFormatter = NumberFormat.getIntegerInstance(); integerFieldFormatter.setMaximumFractionDigits(0); integerField = new JFormattedTextField(integerFieldFormatter ); integerField.setColumns(5); .......... I meant to use it with integer numbers only, but when I type numbers like 1500 it is converted after losing focus to 1,500 , and exception thrown this is the first line

I'm doing a Sudoku solver and for that I want my JTextFields to only accept one of the numbers 123456789 as valid input. Therefore I use a MaskFormatter toghether with a JFormattedTextField. However when I clear all the TextFields by doing .setText("") the MaskFormatter doesn't work anymore. After clearing the textboxes I can write anything in them again. Why and how do I fix it? My code is basically: MaskFormatter formatter = new MaskFormatter("#"); formatter.setValidCharacters("123456789"); Font textFieldFont = new Font("Verdana", Font.BOLD, 30); for (int i = 0; i < 9; i++) { for (int j = 0;
