tablecelleditor

i'm using a JSpinner like a table cell editor, i have one annoying problem: The cell remains in NON-editable mode until i click into it, for NON-editable i mean that i can't write into it(it has not focus so it doesn't accept inputs keyboard) but i can change the value with up-down arrows(of keyboard). So, what i have to do to focus my table cell as soon as i press a key when it is selected? Except for that problem my SpinnerEditor class works quite well. Thanks all. Here's a complete example. It does more than just put the JSpinner in the table, so you can read it and take what you need. I

I have a JTable that has two columns ( editable JTable ). When a user types something in the second column, my requirement is as follows: user can only typewrite a number and comma when user type wrong character, it will beep (Toolkit.getDefaultToolkit().beep(); ) How do I go about achieving this? ( if it jtextfield it need document filter or plain document etc, if it JTable, then how? ) MadProgrammer Implement a TableCellEditor that is capable of returning a text component ( JTextField ) that has a DocumentFilter attached to it capable of filtering the incoming text as you require.

CellEditorListener has "editingStopped" and "editingCancelled". But how might I implement a piece of code which needs to run when a cell editing session starts? A typical example might be where you want the text of a JTextField editor component to go selectAll() when you start editing. I'm tempted to think the thing to do is override one of the methods of DefaultCellEditor, such as getTableCellEditorComponent or getCellEditorValue or getComponent, but none of these explicitly says they are called at the start of an edit session. Conversely, we do know that JTable.getCellEditor returns the

I have a custom JTable with a custom TableModel using a JComboBox as a cell editor. The ComboBox also has a custom ComboBoxModel The ComboBox model holds multiple fields that will be used to update the data behind the JTable and afterwards update a database. The following is a simple example to show the problem I am encountering. Steps to reproduce: Click on an cell Select a value from the ComboBox drop-down list Click on a different cell Click back on the first selected cell The second cell will get the value from the first one. Why is this happening? Why does the ComboBox model change before

i have seen some example of doing it but i still can't understand and not able to implement it. What i want to do is on cell change (focus), the next selected cell will have all the text selected, ready for user to totally change it.. Any ideas on how to do it ? //update// somehow i managed to come out with the following class but implement this tblLayers.setDefaultEditor(String.class, new Classes.CellEditor()); yields nothing, the "Not supported yet." is NOT thrown .. how should I solve this problem ? import java.awt.Component; import java.util.EventObject; import javax.swing.JTable; import

I have a written an AbstractTableModel for my JTable in my application. I see from tutorials that I can make the column to have a combobox by getting the column model and then the specific column for example: TableColumn sportColumn = table.getColumnModel().getColumn(2); ... JComboBox comboBox = new JComboBox(); comboBox.addItem("Snowboarding"); comboBox.addItem("Rowing"); comboBox.addItem("Chasing toddlers"); comboBox.addItem("Speed reading"); comboBox.addItem("Teaching high school"); comboBox.addItem("None"); sportColumn.setCellEditor(new DefaultCellEditor(comboBox)); But how do I do this
