java - 在frameview或主框架之前插入JDialog

Question

i want to add Jdialog before frameview...my frameview consist of my main page of application. i just want to add Jdialog which get password from user and then enter in the Main frame. can any one tell me how can i achieve this in java swing??

Answer 1

MyMainPanel mainPanel = new MyMainPanel();
LoginPanel loginPanel = new LoginPanel();

JFrame mainApp = new JFrame();
mainApp.add( mainPanel );
mainApp.pack();
mainApp.setVisible(true);

JDialog dialog = new JDialog( mainApp, true );
dialog.add( loginPanel );
dialog.setVisible( true );

if( login.isAuthenticated() ) { // after dialog is dismissed we can set the user
    mainPanel.setAuthenticatedUser( loginPanel.getAuthenticatedUser() );
} else {
    System.exit(-1);
}

这将在主面板前面显示一个对话框，用户在登录之前将无法使用它，因为它是模态的，并且您的 LoginPanel 可以通过除了登录之外不提供任何其他选项来强制用户登录，注册等
