要的呀.就是确定和取消按钮,在这两个键上使用左-> 和右<- 默认就是鼠标

Answer 2

Set forwardKeySet = new HashSet();
Set backwardKeySet = new HashSet();  KeyboardFocusManager focusManager = KeyboardFocusManager.getCurrentKeyboardFocusManager();
forwardKeySet.addAll(focusManager.getDefaultFocusTraversalKeys(KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS));
backwardKeySet.addAll(focusManager.getDefaultFocusTraversalKeys(KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS));

forwardKeySet.add(KeyStroke.getKeyStroke(KeyEvent.VK_DOWN, 0, false));
backwardKeySet.add(KeyStroke.getKeyStroke(KeyEvent.VK_UP, 0, false));

focusManager.setDefaultFocusTraversalKeys(KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, forwardKeySet);
focusManager.setDefaultFocusTraversalKeys(KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS, backwardKeySet); JOptionPane.showConfirmDialog(null, "Test", "Test", JOptionPane.YES_NO_CANCEL_OPTION);

谢谢,我想问一下怎么支持回车键呀?
int selection = JOptionPane.showConfirmDialog(null,"\n请病人出示凭证" 
if(selection == JOptionPane.CANCEL_OPTION){ // 按下取消按钮
// 用鼠标点击可以执行,用回车键就不行,请求帮助
  txtCardNo.setEditable(true);
  txtCardNo.requestFocus();
  txtCardNo.setText("");
}else{ // 按下确定按钮
  cardDisplayInfo();
  txtDept.requestFocus();// 部门科室获得焦点  
}

Answer 4

确定和取消按钮,在这两个键上使用左-> 和右<- 
－－－－－－－－
好像都是用Tab键吧

Answer 5

那是默认功能.我要的是回车执行else{ // 按下确定按钮
  cardDisplayInfo();
  txtDept.requestFocus();// 部门科室获得焦点  
}
