Question

我试过以下程序用于java鼠标适配器类的测试鼠标移动方法，但它没有用。我想在鼠标悬停按钮上移动鼠标时，将进度条的值从2增加。我该如何解决这个问题？

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

class ProgressDemo extends JFrame{
    private JProgressBar progress;
    private JButton mouseButton;
    static int x = 2;
    ProgressDemo(){
        progress = new JProgressBar(JProgressBar.HORIZONTAL,0,100);
        progress.setBounds(50,100,500,15);
        progress.setStringPainted(true);
        mouseButton = new JButton("Mouse Over");
        mouseButton.addMouseListener(new MouseAdapter(){
            public void mouseMoved(MouseEvent evt){
                progress.setValue(x+=2);
            }
        });


        JPanel mousePanel = new JPanel(new FlowLayout(FlowLayout.CENTER));
        mousePanel.setBounds(0,10,600,50);
        mousePanel.add(mouseButton);

        setSize(600,200);
        setLayout(null);
        add(mousePanel);
        add(progress);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setLocationRelativeTo(null);
    }
}

class JProgress{
    public static void main(String args[]){
        ProgressDemo p1 = new ProgressDemo();
        p1.setVisible(true);
    }
}

修改您的代码，如下所示。希望它能帮助你进步。

.config(function($stateProvider, $urlRouterProvider, mainItemsList) {
    $stateProvider
        .state('app', {
            url: "/app",
            abstract: true,
            templateUrl: "templates/navigationDrawer.html",
            controller: 'AppCtrl'
        })

    .state('app.masterList', {
            url: "/masterList",
            views: {
                'menuContent': {
                    templateUrl: "templates/masterList.html",
                    controller: 'indexCtrl'
                }
            }
        })
        .state('app.login', {
            url: "/login",
            views: {
                'menuContent': {
                    templateUrl: "templates/login.html",
                    controller: 'loginCtrl'
                }
            }
        })

    .state('app.register', {
        url: "/register",
        views: {
            'menuContent': {
                templateUrl: "templates/register.html",
                controller: 'registerCtrl'
            }
        }
    });
    // if none of the above states are matched, use this as the fallback
    $urlRouterProvider.otherwise(function() {
        var logged = mainItemsList.isLoggedIn();
        // Check User logined or not
        if (logged != true) {
            return 'app.login';
        } else {
            return 'app.masterList';
        }

    });


});
