像JTable单元格编辑器一样使用JSpinner
我正在使用JSpinner像表格单元格编辑器，我有一个恼人的问题：
单元格保持不可编辑模式，直到我点击进入它，因为不可编辑我的意思是我无法写入它（它没有焦点所以它不接受输入键盘）但我可以用更改值 – 向下箭头（键盘）。
那么，当我选择一个按键时，我必须做些什么来集中我的表格？
除了那个问题，我的SpinnerEditor类运行得很好。
谢谢大家。
这是一个完整的例子。 它不仅仅是将JSpinner放在表格中，因此您可以阅读它并获取所需内容。 我发现Blow的答案是不完整的，它对我不起作用，所以这里有你可以编译和运行的东西。
import java.awt.*; import java.awt.event.*; import java.util.*; import javax.swing.*; import javax.swing.table.*; public class JSpinnerInTables { static String[] columnNames = { "Name","Value" }; static Object[][] data = { {"one",1.0}, {"two",2.0} }; public static void main( String[] args ) { JFrame frame = new JFrame(); JTable table = new JTable(data,columnNames); //table.setSurrendersFocusOnKeystroke(true); TableColumnModel tcm = table.getColumnModel(); TableColumn tc = tcm.getColumn(1); tc.setCellEditor(new SpinnerEditor()); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.add(table); frame.pack(); frame.setVisible(true); } public static class SpinnerEditor extends DefaultCellEditor { JSpinner spinner; JSpinner.DefaultEditor editor; JTextField textField; boolean valueSet; // Initializes the spinner. public SpinnerEditor() { super(new JTextField()); spinner = new JSpinner(); editor = ((JSpinner.DefaultEditor)spinner.getEditor()); textField = editor.getTextField(); textField.addFocusListener( new FocusListener() { public void focusGained( FocusEvent fe ) { System.err.println("Got focus"); //textField.setSelectionStart(0); //textField.setSelectionEnd(1); SwingUtilities.invokeLater( new Runnable() { public void run() { if ( valueSet ) { textField.setCaretPosition(1); } } }); } public void focusLost( FocusEvent fe ) { } }); textField.addActionListener( new ActionListener() { public void actionPerformed( ActionEvent ae ) { stopCellEditing(); } }); } // Prepares the spinner component and returns it. public Component getTableCellEditorComponent( JTable table, Object value, boolean isSelected, int row, int column ) { if ( !valueSet ) { spinner.setValue(value); } SwingUtilities.invokeLater( new Runnable() { public void run() { textField.requestFocus(); } }); return spinner; } public boolean isCellEditable( EventObject eo ) { System.err.println("isCellEditable"); if ( eo instanceof KeyEvent ) { KeyEvent ke = (KeyEvent)eo; System.err.println("key event: "+ke.getKeyChar()); textField.setText(String.valueOf(ke.getKeyChar())); //textField.select(1,1); //textField.setCaretPosition(1); //textField.moveCaretPosition(1); valueSet = true; } else { valueSet = false; } return true; } // Returns the spinners current value. public Object getCellEditorValue() { return spinner.getValue(); } public boolean stopCellEditing() { System.err.println("Stopping edit"); try { editor.commitEdit(); spinner.commitEdit(); } catch ( java.text.ParseException e ) { JOptionPane.showMessageDialog(null, "Invalid value, discarding."); } return super.stopCellEditing(); } } } 好的，我现在的解决方案是：
spinner.addFocusListener(new FocusListener() { public void focusGained(FocusEvent e) { // editor is ((JSpinner.DefaultEditor)spinner.getEditor()).getTextField(); // necessary to set focus on the text component of jspinner editor.requestFocus(); // this if you want to select the displayed text of jspinner SwingUtilities.invokeLater(new Runnable() { public void run() { System.out.println("run"); editor.selectAll(); } }); } public void focusLost(FocusEvent e) {} });
