• Java JSpinner Prevent Letter Insertion

  - by asmo

  A JSpinner is used to store a number in my application (with a SpinnerNumberModel). As expected, the spinner doesn't allow invalid characters (letters, symbols, etc.) to be stored. However, those characters do appear in the spinner component when I type them in. As soon as I switch the focus to another component, they disappear. Is there a way to prevent invalid characters from appearing in the spinner?

• Java Swing - Problem in JSpinner

  - by Yatendra Goel

  I am developing a Java Desktop Application and designing the GUI with the help of Netbeans Swing GUI builder. I want to use a JSpinner in my app. I have dragged and dropped it to a JPanel. Now, I want to set its two properties: First, It should display numbers in the range of 1 to 50. Neither less than 1 nor greater than 50. How can I set that range? Second, when I try to get the value of it by spinner.getValue() it returns an Object. As my spinner's data type is Integer, would it be better to downcast the Object into Integer or Is there any other way to get that numeric value?

• JTable - Getting a cell into Edit mode on pressing Tab

  - by Luhar

  This is possibly has a trivial solution, but I am at the end of my tether so I hope somebody can help out. I use a JTable which has a custom renderer and a custom editor for a set of columns. The renderer uses a JLabel component and the editor uses a JSpinner component. Our users want to be able to enter values in a column, and then press TAB or ENTER to move to the next editable cell in the table. If I understand correctly, this is the default behaviour for a JTable. However, this doesn't seem to work correctly for me. Until the user clicks on the cell, only the JLabel is displayed. The JSpinner (i.e. CellEditor) is only displayed when a user double clicks on the cell. So, it looks like the cell is going into "edit" mode only on MouseEvents, but not when it has focus. How do I get the cell to go into edit mode as soon as it has focus?
