如何使一個JTable單元（鏈接）可點擊

JXTable table = new JXTable(myModel); 
AbstractHyperlinkAction<Object> simpleAction = new AbstractHyperlinkAction<Object>(null) { 

    public void actionPerformed(ActionEvent e) { 
     // here goes what you want to do on activating the hyperlink 
     //LOG.info("hit: " + getTarget()); 
    } 

}; 
TableCellRenderer renderer = new DefaultTableRenderer(
    new HyperlinkProvider(simpleAction)); 
table.getColumnExt(0).setEditable(false); 
table.getColumnExt(0).setCellRenderer(renderer);

是的這就是我認爲的答案。 – 2014-05-15 16:31:57

如何在特定的鼠標事件上觸發此操作 - 即右鍵單擊？目前，這將觸發任何鼠標左鍵或右鍵。 – jeemar 2015-07-13 20:58:51

我認爲，避免外部庫是一個更好的方式去爲MadProgrammer建議，但我想swingx仍然是純java。無論如何，我會使用mouseClicked監聽器，然後以這個問題How to add hyperlink in JLabel中描述的方式打開uri。

JTable table = new JTable(); 

table.addMouseListener(new MouseAdapter() { 
    public void mouseClicked(MouseEvent e) { 

     int row = table.getSelectedRow(); 
     int col = table.getSelectedColumn(); 

     //build your address/link 

     URI uri = new URI("http: your link here"); 

     //see below 
     open(uri); 
     } 
    }); 

//Then elsewhere as from the McDowell answer 
private static void open(URI uri) { 
    if (Desktop.isDesktopSupported()) { 
    try { 
     Desktop.getDesktop().browse(uri); 
     } catch (IOException e) { /* TODO: error handling */ } 
    } else { /* TODO: error handling */ } 
}

我解決加入可點擊在細胞內的按鈕，我跟着這個教程Table Button Column來自Rob Camick：

String[] columnNames = {"First Name", "Last Name", ""}; 
Object[][] data = 
{ 
    {"Homer", "Simpson", "delete Homer"}, 
    {"Madge", "Simpson", "delete Madge"}, 
    {"Bart", "Simpson", "delete Bart"}, 
    {"Lisa", "Simpson", "delete Lisa"}, 
}; 

DefaultTableModel model = new DefaultTableModel(data, columnNames); 
JTable table = new JTable(model);

然後：

Action delete = new AbstractAction() 
{ 
    public void actionPerformed(ActionEvent e) 
    { 
     JTable table = (JTable)e.getSource(); 
     int modelRow = Integer.valueOf(e.getActionCommand()); 
     ((DefaultTableModel)table.getModel()).removeRow(modelRow); 
    } 
}; 

ButtonColumn buttonColumn = new ButtonColumn(table, delete, 2); 
buttonColumn.setMnemonic(KeyEvent.VK_D);

哪裏ButtonColumn類是：

import java.awt.*; 
import java.awt.event.*; 
import javax.swing.*; 
import javax.swing.border.*; 
import javax.swing.table.*; 

/** 
* The ButtonColumn class provides a renderer and an editor that looks like a 
* JButton. The renderer and editor will then be used for a specified column 
* in the table. The TableModel will contain the String to be displayed on 
* the button. 
* 
* The button can be invoked by a mouse click or by pressing the space bar 
* when the cell has focus. Optionally a mnemonic can be set to invoke the 
* button. When the button is invoked the provided Action is invoked. The 
* source of the Action will be the table. The action command will contain 
* the model row number of the button that was clicked.
