如何将Jframe调用为主Jfram [英] How to call Jframe into main Jfram
本文介绍了如何将Jframe调用为主Jfram的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在从事股票市场项目.我要制作显示股市图表和新闻的桌面应用程序.到目前为止，我已经制作了一个具有RSS的主框架(类)，第二个框架是显示烛台图表(2类)的applcationframe.我想将图表放入主框架.如何将其放入我的主框架/(或如何将应用程序框架放入框架).我将非常感谢所有建议.
这是主机的代码:
这是单独的烛台图:
如果我只想创建一种在主框架中显示图表的方法，该怎么办?

解决方案
例如，IB TWS使用JFreeChart绘制图表.
您可以使用插入HTML代码.
I have working on stock market project. I want to make desktop app which shows stock markets chart and news. I have made so far a main frame (class) which has RSS and the second is applcationframe which shows candle stick chart (2 class). I would like to place the chart into my main frame. How can place it into my main frame/ (or how can I call application frame into frame). I will truly appreciate all advices.
Here is the code for main frame:
import java.awt.BorderLayout;
public class Boeing extends JFrame {
private JPanel contentPane;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Boeing frame = new Boeing();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
public static String readRSS(String urlAddress) {
try{
URL rssUrl = new URL(urlAddress);
BufferedReader in = new BufferedReader(new InputStreamReader(rssUrl.openStream()));
String sourceCode = "";
String line;
while((line = in.readLine())!=null) {
if (line.contains("<title>")){
int firstPos = line.indexOf("<title>");
String temp = line.substring(firstPos);
temp = temp.replace("<title>", "");
int lastPos = temp.indexOf("</title>");
temp = temp.substring(0,lastPos);
sourceCode += temp + "\n" + "\n";
}
}
in.close();
return sourceCode;
} catch (MalformedURLException ue){
System.out.println("Malformed URL");
} catch (IOException ioe) {
System.out.println("Something went wrong reading the cotents");
}
return null;
}
public Boeing() {
setResizable(false);
setExtendedState(Frame.MAXIMIZED_BOTH);
setTitle("StockIn");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 1350, 695);
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
setContentPane(contentPane);
contentPane.setLayout(null);
JMenuBar menuBar = new JMenuBar();
menuBar.setBounds(0, 0, 1280, 22);
contentPane.add(menuBar);
JMenu mnStockin = new JMenu("StockIn");
menuBar.add(mnStockin);
JMenuItem mntmQuitStockin = new JMenuItem("Quit StockIn");
mntmQuitStockin.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
System.exit(0);
}
});
JMenuItem mntmHome = new JMenuItem("Home");
mntmHome.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
Intro intro = new Intro();
intro.setVisible(true);
dispose();
}
});
mnStockin.add(mntmHome);
JSeparator separator = new JSeparator();
mnStockin.add(separator);
mnStockin.add(mntmQuitStockin);
JMenu mnLse = new JMenu("LSE");
menuBar.add(mnLse);
JMenuItem mntmBoeing = new JMenuItem("BOEING CO");
mntmBoeing.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
Boeing boeing = new Boeing();
boeing.setVisible(true);
dispose();
}
});
mnLse.add(mntmBoeing);
JSeparator separator_16 = new JSeparator();
mnTSE.add(separator_16);
mnTSE.add(mntmSony);
TextArea textArea = new TextArea(readRSS("http://boeing.mediaroom.com/news-releases-statements?pagetemplate=rss"));
textArea.addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent arg0) {
}
});
textArea.setEditable(false);
textArea.setBounds(684, 396, 596, 277);
contentPane.add(textArea);
Panel panel = new Panel();
panel.addComponentListener(new ComponentAdapter() {
@Override
public void componentResized(ComponentEvent arg0) {
}
});
panel.setBackground(Color.PINK);
panel.setBounds(684, 28, 596, 368);
contentPane.add(panel);
/* JLabel dice1 = new JLabel();
ImageIcon one = new ImageIcon("/Users/odzayaBatsaikhan/Desktop/chart.png");
dice1.setLocation(20, 100);
dice1.setSize(1000, 400);
dice1.setIcon(one);
contentPane.add(dice1);*/
}
}
Here is separate Candlestick chart:
If i want to just create a method to show charts in main frame, how can do this?

解决方案
JFreeChart is used by IB TWS for example to draw charts.
You can insert HTML code into swing using .
