jspinner

问题 I have a numeric JSpinner which accepts values in a specific measuring unit. Now, I'd like to have a special JSpinner behavior: If a user enters a numeric value and appends a specific measuring unit string (e.g. "inch", "pica") then the entered numeric value must be converted into another value (depending on the unit string). This conversion must occur when user leaves the spinner field (focus lost) or if a "commitEdit" occurs in any way. I've tried several variants: Custom document filter,

问题 I'm currently having a problem in netbeans where my JSpinner is allowing you to type in the textfield while I only want the arrows to be used. Is there a way to disable the input of text via properties or some other way? Thanks 回答1: Disable the JSpinner's JTextField's using the following: ((JSpinner.DefaultEditor) yourSpinner.getEditor()).getTextField().setEditable(false); 回答2: You can try it like this JSpinner.DefaultEditor editor = ( JSpinner.DefaultEditor ) component.getEditor(); editor

问题 I would like to allow both "comma" and "dot" as separator in double. I could use replace method in string to get only one separator, but problem is that double value is value of JSpinner and I was not able to find any method to allow both separators. If I set locale for example to French only one separator is allowed. 回答1: Just use a custom formatter for the JFormattedTextField of the DefaultEditor of the JSpinner , like the code below: import java.text.ParseException; import javax.swing

问题 I am trying to make a JSpinner (containing a minute/second timer) work for a bunch of set-in-their-ways folks who don't care beans about the mouse but want every keystroke to do exactly what they are used to. It works almost as I'd like it to but the last mile is the hardest. What this means in practice is that the spinner should look and behave when one of its text fields gains focus exactly as it looks and behaves after the user has pressed an arrow key from one of those fields. Spinner is
