#2419 — [Swing] Is it possible to

  To: comp.lang.java.gui
I am in the process of designing a very simple menu system which will
have a series of button, a sort of hierarchical system if you will.
What I would like to do is have each button open a webpage in the user's
default browser.  Is this possible and if so, are there any examples
that someone would be willing to share?  I have googled, but either I am
not searching for the right thing, or there are NO websites which meet
my criteria.

If using 1.6, java.awt.Desktop is the way to go.

try {
  Desktop.browse(new URL("http://www.rgagnon.com");
} 
catch (MalformedURLException e1) {
   e1.printStackTrace();
} 
catch (DesktopException e2) {
   e2.printStackTrace();
}

For pre 1.6, you need to use Runtime.exec() and the file association
mechanism of the OS. 

Bye.

  To: comp.lang.java.gui
On Tue, 11 Sep 2007 21:51:18 GMT, Real Gagnon expounded upon us in 
comp.lang.java.gui :

> http://www.rgagnon.com

Thanks for the help.  Since I don't know what JDK will be used by 
the people invoking my screen, I had to go with the Runtime.exec() 
option

private void jButton30ActionPerformed(java.awt.event.ActionEvent 
evt) {                                          
// TODO add your handling code here:
        String url = "http://www.rgagnon.com";
        try {
            Runtime.getRuntime().exec("cmd /C start 
http://www.rgagnon.com");
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }                                         

Is there a way to draw horizontal and vertical lines on a screen 
like this

           Main
      ------|------
      |     |     |
      F1    F2    F3

where Main, F1, F2 and F3 are JButtons?

Note that approach is explored in some detail in
the code of BrowserLauncher2.

Also, JWS apps. have access to the BasicService.showDocument()
method, and applets might use the (utterly unreliable)
AppletContext.showDocument().  Both of those are avialable
since 'inception' (1.1 for the applet, 1.2 for JWS)
