示例1: keyPressed
import javax.swing.JTextField; //導入方法依賴的package包/類
@Override
public void keyPressed(KeyEvent ke) {
int keyCode = ke.getKeyCode();
Object keSource = ke.getSource();
JTextField jTextField = (JTextField) keSource;;
int caretPos = jTextField.getCaretPosition();
int textLength = jTextField.getText().length();
if(keyCode == KeyEvent.VK_ESCAPE){
// Due to a java bug, the callback method is not called automatically when pressing escape.
cancelCellEditing();
} else if(keyCode == KeyEvent.VK_ENTER || keyCode == KeyEvent.VK_TAB){
// Remember which key was used to confirm editing
confirmationKey = keyCode;
} else if(keyCode==KeyEvent.VK_RIGHT && caretPos==textLength){
confirmationKey = keyCode;
stopCellEditing();
} else if(keyCode==KeyEvent.VK_LEFT && caretPos==0){
confirmationKey = keyCode;
stopCellEditing();
}
