Basically Swing JComponents are able to display numbers in fractions in this form 2 2/3 . How can I paint fraction in the nicest form, for example 2⅔? . EDIT . as see I have only one way JTable inside JSpinner with one TableColumn and TableRow (that could simulated plain JtextField too), where TableRenderer could be some of JTextComponent formatted by using Html and on TableCellEdit event the TableEditor to swith to the plain JFormattedTextField , is there another way, could it be possible with plain J(Formatted)TextField too ??? trashgod On reflection, Unicode fractions among the Latin-1

问题 I am creating time picker using a JSpinner . The text inside the JSpinner is editable. But I want to set the JSpinner as non editable, because there is the chance to give an invalid value. Can anyone help me? 回答1: Try the following: JSpinner spinner = ...; ((DefaultEditor) spinner.getEditor()).getTextField().setEditable(false); This should work as long as you didn't change the spinner editor yourself by calling spinner.setEditor(...) . Tell us if this helps. 回答2: A bit shorter: JSpinner

JSpinner: Display a range of signed HexBinary values

由 笑着哭i 提交于 2019-11-26 17:19:45
问题 What is the best way to display a range of signed HexBinary numbers in a JSpinner ? e.g. from 0x8000 to 0x7ffe I have tried the following solutions, without much luck: Use a JSpinnerNumberModel with a default formatter to convert from int to Hexbinary.[Cannot display negative part of the range] Use a JSpinnerListModel and pass it a constructed list of HexBinary values that fall in the range (contrived solution with unnecessary code. doesn't work perfectly). Is there a better, generic solution
