java - 将JApplet添加到JPanel

我正在Swing中开发新的应用程序，并且想在该应用程序中重用JChempaint。我有JChempaint applet的jar文件（使用JApplet在Swing中开发）。

基本上，我想在新应用程序中将jar文件添加到JPanel。无论如何，这可能吗？ JChempaint正在开源，我也有源代码。

如何将JChempaint小程序添加到面板？



以下是尝试实施建议后的详细信息------
我从我的项目开始，尝试开发一个框架，将JChemPaint窗口嵌入其中。
以下是我的布局代码：

package LearnSwingPkg;

import java.awt.BorderLayout;

class SplitPane extends JFrame  {

private JPanel panel1;
private JPanel panel2;
private JScrollPane panel3;
private JScrollPane panel4;

protected JSplitPane split;

public SplitPane(){

    super("Learn Swing");
    JFrame.setDefaultLookAndFeelDecorated(true);
    setSize(900, 700);
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    setLocation(0,0);

    setTitle( "Split Pane Application" );

    JPanel topPanel = new JPanel();
    topPanel.setLayout( new BorderLayout() );
    getContentPane().add( topPanel );

    // Create the panels
    createPanel1();
    createPanel2();
    createPanel3();
    createPanel4();

    JSplitPane spLeft = new JSplitPane(JSplitPane.VERTICAL_SPLIT, true,panel1, panel3);
    JSplitPane spRight = new JSplitPane(JSplitPane.VERTICAL_SPLIT,true, panel2, panel4);

    split = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, true,spLeft, spRight);
    split.setOneTouchExpandable(true);

    getContentPane().add(split, BorderLayout.CENTER);



}
//top left
public void createPanel1(){
    panel1 = new JPanel();
    panel1.setLayout( new BorderLayout() );
    panel1.add((new TextArea("Panel1")));

    panel1.setPreferredSize( new Dimension( 450, 400 ) );
    panel1.setMaximumSize(new Dimension(450, 400));
}


//top right
public void createPanel2(){
    panel2 = new JPanel();
    panel2.setLayout( new BorderLayout() );
  panel2.add((new TextArea("Panel2")));
    panel2.setPreferredSize( new Dimension( 450, 400 ) );
    panel2.setMaximumSize(new Dimension(450, 400));

}

//bottom left
public void createPanel3(){
    Label label_prop = new Label("Properties:", Label.LEFT);

   String[] columnNames = {"Properties",
            "",
          };
    Object[][] data = {
            {"", "",}, {"", ""}, {"", ""},{"", ""},
            {"", "",}, {"", ""}, {"", ""},{"", ""},
            {"", "",}, {"", ""}, {"", ""},{"", ""}
            };


    JTable table = new JTable(data, columnNames);
    table.setBackground(getBackground());
    table.setBackground(Color.LIGHT_GRAY);
    table.setRowHeight(20);
    table.setBorder(BasicBorders.getMenuBarBorder());

    panel3 = new JScrollPane(table, JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, JScrollPane.HORIZO
    panel3.add(label_prop);
    panel3.setPreferredSize( new Dimension( 20, 20 ) );
    panel3.setMinimumSize( new Dimension( 20, 20 ) );

}
//bottom right
public void createPanel4(){

     panel4 = new JScrollPane();
        //panel4.setLayout( new FlowLayout() );
     String[] columnNames = {"Activities",
                "",
              };
        Object[][] data = {
                    {"", "",}, {"", ""}, {"", ""},{"", ""},
                    {"", "",}, {"", ""}, {"", ""},{"", ""},
                    {"", "",}, {"", ""}, {"", ""},{"", ""}
                    };


        JTable table = new JTable(data, columnNames);
        table.setBackground(getBackground());
        table.setBackground(Color.LIGHT_GRAY);
        table.setRowHeight(20);
        table.setBorder(BasicBorders.getMenuBarBorder());
        panel4 = new JScrollPane(table, JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
    panel4.setPreferredSize( new Dimension( 20, 20 ) );
    panel4.setMinimumSize( new Dimension( 20, 20 ) );


}

public static void main( String args[] ){
    try {
        UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
    } catch (Exception evt) {}
    // Create an instance of the test application
    SplitPane mainFrame = new SplitPane();
    mainFrame.setVisible( true );
    mainFrame.setBackground(Color.blue);
    }
}

暂时，我试图在上面的代码中插入一个空表。稍后，它将填充相关数据。

这给了我一个有四个块的Frame，左上方有JCHemPaint窗口，下两个块有一个表格。

现在，为了在面板1中添加JChemPaint，我编辑了该文件中的代码。更改了createPanel1方法：

//top left
public void createPanel1(){
    panel1 = new JPanel();
    panel1.setLayout( new BorderLayout() );
    JChemPaint.showInstance(filename, null, null, debug);
    panel1.setPreferredSize( new Dimension( 450, 400 ) );
    panel1.setMaximumSize(new Dimension(450, 400));
}

这仅向我输出JChemPaint窗口。

如果我使用框架，则无法将其放置在面板1中。
我怎样才能做到这一点？
谢谢！

最佳答案

如here所建议，JChemPaint是标准Java应用程序。有关构造showInstance()并将其添加到JChemPaintPanel的示例，请参见JFrame。
