私はJavaFXのことを頭に入れようとしています...私のプログラムはWindowBuilderベースのGuiで、JavaFXグラフとJavaFXライブビデオフィードをアプリに表示したいです。
コードに実装するにはどうすればよいですか? これを試しましたが、実行できませんでした。データフィードは問題ではありません。JFrame内で小さな正方形として表示するだけです...
今混乱しています:(
これが私のコードです: (少し長くて申し訳ありませんが、JavaFX のサンプルコードのせいです:p
import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.UIManager;
import java.awt.Canvas;
import java.awt.SystemColor;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import javax.swing.UIManager.*;
/**
* @author
*
*/
public class MyClientApp extends JFrame {
/**
*
*/
private static final long serialVersionUID = 1L;
protected static final String BufferedWriter = null;
JFrame frame;
private JTextField textFieldUsername;
/**
* Create the application.
*/
public MyClientApp(BufferedWriter serverDataOut, BufferedReader serverDataIn) {
initialize();
}
/**
* Initialize the contents of the frame.
*
* @param serverDataOut
*
*/
private void initialize() {
try {
for (LookAndFeelInfo info : UIManager.getInstalledLookAndFeels()) {
if ("Nimbus".equals(info.getName())) {
UIManager.setLookAndFeel(info.getClassName());
break;
}
}
} catch (Exception e) {
// Nimbus Theme not avaliable
}
frame = new JFrame();
frame.setResizable(false);
frame.setTitle("*********** My Program ***********");
frame.setBounds(320, 130, 730, 570);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(null);
Canvas canvasTemp = new Canvas();
canvasTemp.setBackground(SystemColor.window);
canvasTemp.setBounds(6, 277, 380, 255);
frame.getContentPane().add(canvasTemp);
Canvas canvasLevel = new Canvas();
canvasLevel.setBackground(SystemColor.window);
canvasLevel.setBounds(6, 10, 380, 255);
frame.getContentPane().add(canvasLevel);
}
public JFrame frame() {
return frame;
}
}
そして、これがあなたのために実行するためのメインファイルです...:
Client.java
import java.io.IOException;
public class Client {
public static void main(String[] args) throws IOException, InterruptedException {
MyClientApp window = new MyClientApp(null, null);
window.frame.setVisible(true);
}
}
