I have started a button in my class like this:
linkBtn = New LinkButton (new) URI ("http://www.example.com"), "Click Me"); When I click it, nothing happens, so I want to add an action listener like this: pre <> linkBtn.addActionListener (some);
I tried this way:
linkBtn.addActionListener (new link button. OpenUrLections ()); This returns the following error:
An attached example that requires LinkButton.OpenUrlAction
I Until right syntax was not found.
Here is my class that extends the pocket button:
import java.awt.Desktop; Import java.awt.event.ActionEvent; Import java.awt.event.ActionListener; Import java.io.IOException; Import java.net.URI; Import javax.swing.JButton; Public class Linkbunballton applies ActionListener {/ ** Target of this link or href * / Private URI target; Last fixed private string default text = "& lt; HTML>
I'm open to suggestions. I do not like the structure of my program. .
