複数のコンポーネントを持つソフトウェアを設計しています。それぞれに独自のアクション リスナーがあります。たとえば、10 枚のカードを保持するカードレイアウトを持つ JPanel があります。それぞれに独自の JPanel と目的があります。
片側には複数のボタン、IE ログイン、ログアウト、設定などがあります。
[ログイン] をクリックすると、ログイン JPanel オブジェクトへの Login() メソッドを使用してカードに切り替わり、[IE ログイン]、[新規ユーザー]、または [キャンセル] ボタンがクリックされるのを待ってから、Login() メソッドと設定を続行します。現在のユーザー。
いずれかのボタンをクリックしてデータを取得するまでプログラムを一時停止する方法はありますか? ( JOptionPane.showInputMessage(null,"INPUT STRING") があなたを待つ方法のようなものです)
私のコードは以下の通りです: フレーム:
/**

public class Frame extends JFrame{
JPanel LeftSide, UpperRightSide;
EmployeeAdder employAdd;
ArrayList<ServiceView> serviceViewers;
ChartViewer viewChart;
PayByView viewPayBy;

public static String CARDCAT = "Category View";
public static String CARDPAY = "Pay By";
public static String CARDCHART = "Chart View";
public static String CARDLOGIN = "Log-in View";
public static String CARDSERVICEADD = "Service Adder";
Frame(){
listen = new ButtonListen();
//-------Current Card--------------------
currentCard = CARDCAT;
currentRightCard = "CHARGE";
//-----First Find Directory Folder-------
startDirectory();
//-----User Interface--------------------
//-------Left Side-----------------------
LeftSide = new JPanel();
LeftCard = new CardLayout();
LeftSide.setLayout(LeftCard);
viewPayBy = new PayByView();

LeftSide.setBorder(BorderFactory.createTitledBorder(BorderFactory.createLineBorder(Color.BLACK),currentCard));
serviceViewers = new ArrayList<ServiceView>();
//--------Right Side---------------------
JPanel RightSide = new JPanel();
RightSide.setLayout(new BorderLayout());
UpperRightSide = new JPanel();
RightCard = new CardLayout();
UpperRightSide.setLayout(RightCard);
viewSettings = new SettingsViewer();
viewCharge = new ChargeViewer();
viewCharge.setEnabled(false);
UpperRightSide.add(viewCharge,"CHARGE");
UpperRightSide.add(viewSettings,"SETTINGS");
UpperRightSide.setPreferredSize(new Dimension(350,500));

//--------Buttons at the bottom Panel---

Buttons.setLayout(new GridLayout(3,1));
Login = new JButton("LOG-IN");

}
private void Login(){

//----I WANT IT TO WAIT HERE FOR AN ACTION-------
int clicked = viewLogin.getClicked();
if (clicked==LoginViewer.NEWUSER){
NewUser();
}else if (clicked==LoginViewer.LOGIN){
if (viewLogin.checkPassword()){
currentEmployee = directory.getEmployee(viewLogin.getSelectedName());
viewCategory.setEnabled(true);
viewCharge.setEnabled(true);
viewCharge.refreshName(currentEmployee.getName());
LeftCard.show(LeftSide, "CAT");
}
}else if (clicked==LoginViewer.CANCEL){
LeftCard.show(LeftSide, "CAT");
}
}
public class ButtonListen implements ActionListener{
@Override
public void actionPerformed(ActionEvent e) {
if (!viewLogin.isWaiting()){
if (e.getSource()==Login){
if (currentCard.equals(CARDLOGIN)){
LeftCard.show(LeftSide,"CAT");
currentCard = CARDCAT;
}else{
Login();
currentCard = CARDLOGIN;
}
}else{
//Don't change the screen
}
}
}
}
}
LoginViewerの私のコード：
public class LoginViewer extends JPanel{
JComboBox User;
JPasswordField passField;
JButton NewUser, Login, Cancel;
Hashtable<String,String> namespass; //names and password
private int clicked = -1;
ButtonListen listen;
public static int NEWUSER = 1;
public static int LOGIN = 0;
public static int CANCEL = 2;
boolean waiting;
LoginViewer(){
waiting = false;
//---------------------------------------
setPreferredSize(new Dimension(100,100));
listen = new ButtonListen();
namespass = new Hashtable<String,String>();
//----------Panel Design-------------------
JPanel Center = new JPanel();
Center.setLayout(new GridLayout(3,3));
User = new JComboBox();
passField = new JPasswordField();
NewUser = new JButton("New User");
NewUser.addActionListener(listen);
Login = new JButton("Login");
Login.addActionListener(listen);
Cancel = new JButton("Cancel");
Cancel.addActionListener(listen);
Center.add(new JLabel("Choose User"));
Center.add(User);
Center.add(new JLabel(""));
Center.add(new JLabel("Type Password"));
Center.add(passField);
Center.add(new JLabel(""));
Center.add(Login);
Center.add(NewUser);
Center.add(Cancel);
Center.setPreferredSize(new Dimension(300,300));
Center.setMaximumSize(new Dimension(100,100));
Center.setAlignmentX(CENTER_ALIGNMENT);
setAlignmentX(CENTER_ALIGNMENT);
setLayout(new BoxLayout(this,BoxLayout.X_AXIS));
add(Box.createHorizontalGlue());
add(Center);
add(Box.createHorizontalGlue());
}
public void uploadUserNames(Hashtable<String,String> names){
namespass.clear();
namespass.putAll(names);
User.removeAllItems();
Enumeration<String> name = names.keys();
while (name.hasMoreElements()){
User.addItem(name.nextElement());
}
}
public boolean checkPassword(){
boolean value = false;
String key = User.getSelectedItem().toString();
if (passField.getPassword().length==4){
if (namespass.get(key).equals(String.valueOf(passField.getPassword()))){
value = true;
}
}
return value;
}
public String getSelectedName(){
return User.getSelectedItem().toString();
}
public boolean isWaiting(){
return waiting;
}
public int getClicked(){
waiting = true;
return clicked;
}
public class ButtonListen implements ActionListener{
@Override
public void actionPerformed(ActionEvent e) {
waiting = false;
if (e.getSource()==NewUser){
clicked = 1;
}else if (e.getSource()==Login){
clicked = 0;
}else if (e.getSource()==Cancel){
clicked = 2;
}
}
}
}
それとも、actionlistener を使用してすべてのオブジェクトのボタンをリッスンする方が簡単ですか?
ボタンがたくさんあります...
注: 一部のメソッドは不完全であるか、機能させる方法がわかるまでメソッドをテストしています...
