將JTable添加到分層平面中

Question

我們可以在Java中將Jable添加到JLayeredPane中嗎？

Answer 1

很簡單，使用JInternalFrame。

使用適當的數據創建表格。 （例）

public static void main(String args[]) { 

    JFrame f = new JFrame("JDesktopPane Sample"); 

    JTable jt = new JTable(); 

    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 

    Container content = f.getContentPane(); 

    JLayeredPane desktop = new JDesktopPane(); 

    Object rowData[][] = { { "Row1-Column1", "Row1-Column2", "Row1-Column3"}, 
     { "Row2-Column1", "Row2-Column2", "Row2-Column3"} }; 

    Object columnNames[] = { "Column One", "Column Two", "Column Three"}; 

    JTable table = new JTable(rowData, columnNames); 

    desktop.setOpaque(false); 
    desktop.add(createLayer2(table),JLayeredPane.POPUP_LAYER); 
    content.add(desktop, BorderLayout.CENTER); 
    f.setSize(300, 200); 
    f.setVisible(true); 
} 



public static JInternalFrame createLayer2(JTable n) { 

    return new SelfInternalFrame2(n); 

} 


static class SelfInternalFrame2 extends JInternalFrame { 

    public SelfInternalFrame2(JTable n) { 

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

     setBounds(50, 50, 100, 100); 

     setResizable(true); 

     setClosable(true); 

     setMaximizable(true); 

     setIconifiable(true); 

     setVisible(true); 

    } 

}
