我正在Swing中開發我的新應用程序,並且希望在此應用程序中重用JChempaint。我有JChempaint applet的jar文件(使用JApplet
在Swing中開發)。將JApplet添加到JPanel
基本上,我想jar文件在我的新應用程序添加到JPanel
。無論如何,這可能嗎? JChempaint是開源的,我也有源代碼。
如何將JChempaint小程序添加到面板?
以下是試圖實現的建議------ 我開始與我的項目,並試圖建立一個骨架嵌入JChemPaint窗口之後的細節。 以下是我的佈局代碼:
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);
}
}
對於暫時,我試圖插入一個空表,在上面的代碼。稍後,它將填入相關數據。
這讓我有四個街區的框架,左上角會有JCHemPaint窗口,下兩個街區就會有一個表。
現在,爲了在面板1添加JChemPaint我編輯在此file.I代碼改變了方法createPanel1:
//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));
}
此輸出我只JChemPaint窗口。
我無法將它放入面板1如果我的框架。 我該怎麼做? 謝謝!
「jar」是一個包含Java類和資源的zip文件,它不是Swing組件,因此不能這樣處理。因此,對你的直接問題的簡短回答,''我可以添加一個Jar到JPanel嗎?「是不,你不能。但是,如果jar文件包含從Swing組件(例如JPanel或JComponent)擴展的Swing類,並且文檔或源代碼將能夠告訴您這一點,那麼可以,您可以在您自己的Swing GUI中使用這些類的對象。 – 2014-11-21 00:06:21
非常感謝。這一定會幫助我。 – ksk 2014-11-21 18:45:28
