单击jtable中的超链接? [英] Click hyperlink in jtable?
问题描述
如何为JTable中的每个记录启用超链接?
How can I enable hyperlink for every record in the JTable?
我要做的是使用户可以单击超链接，然后将显示他们可以编辑/更新的信息.
What I want to do is such that a user can click on the hyperlink which will then display the information they can edit/update.
或者，如何启用表格数据的就地编辑?
Alternatively how can I enable in place editing of the table data?
另一个问题是我目前正在使用以下方式显示不同的屏幕.但这不是我理解我们应该使用cardlayout的一种优雅方式，但是如何精确地做到这一点呢?
Another question is i am currently using the following way to display different screen. But this is not an elegant way i understand we should use cardlayout but how exactly to go about it?
mainPanel.setVisible(false);
createBlogEntryPanel.setVisible(true);
setComponent(createBlogEntryPanel);
推荐答案
要解决JTable消耗事件的问题，可以在JTable上添加自己的MouseListener(或MouseAdapter)，然后在此侦听器中进行操作.这是您可以实现的示例:
To address the problem with JTable consuming the events, you can add your own MouseListener (or a MouseAdapter) to the JTable and do your manipulation inside this listener. Here is an example of what you can achieve:
public class Main extends JFrame {
public Main() {
super();
DefaultTableModel dt = new DefaultTableModel(
new String[][] { { "http://google.com" }, { "http://gmail.com" } }, new String[] { "Url" });
final JTable t = new JTable(dt);
t.addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent e) {
int row = t.rowAtPoint(new Point(e.getX(), e.getY()));
int col = t.columnAtPoint(new Point(e.getX(), e.getY()));
System.out.println(row + " " + col);
String url = (String) t.getModel().getValueAt(row, col);
System.out.println(url + " was clicked");
// DO here what you want to do with your url
}
@Override
public void mouseEntered(MouseEvent e) {
int col = t.columnAtPoint(new Point(e.getX(), e.getY()));
if (col == 0) {
t.setCursor(new Cursor(Cursor.HAND_CURSOR));
}
}
@Override
public void mouseExited(MouseEvent e) {
int col = t.columnAtPoint(new Point(e.getX(), e.getY()));
if (col != 0) {
t.setCursor(new Cursor(Cursor.DEFAULT_CURSOR));
}
}
});
add(new JScrollPane(t));
t.getColumnModel().getColumn(0).setCellRenderer(new TableCellRenderer() {
@Override
public Component getTableCellRendererComponent(JTable table, final Object value, boolean arg2,
boolean arg3, int arg4, int arg5) {
final JLabel lab = new JLabel("<html><a href=\"" + value + "\">" + value + "</a>");
return lab;
}
});
setSize(700, 500);
setLocationRelativeTo(null);
setVisible(true);
setDefaultCloseOperation(EXIT_ON_CLOSE);
}
public static void main(String[] args) {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception e) {
e.printStackTrace();
}
new Main();
}
}
