如何在Swing应用程序中使用第三方主题？

Question

I want to use some third party themes (like synthetica http://www.javasoft.de/synthetica/themes/ ) in my swing appliaction. i am using eclipse ide , got the jar file of theme and did the following modification(according to the readme file from the theme) in my code

try 
  {      
   UIManager.setLookAndFeel(new SyntheticaBlackMoonLookAndFeel());
  } 
  catch (Exception e) 
  {
   e.printStackTrace();
  }

but after this modification its showing the following error

 The type de.javasoft.plaf.synthetica.SyntheticaLookAndFeel cannot be resolved. It is indirectly referenced from required .class files

what does this mean? i tried searching on net but cant really find any useful answers

Contents of Readme file:

System Requirements
===================

Java SE 5 (JRE 1.5.0) or above
Synthetica V2.2.0 or above

Integration
===========

1. Ensure that your classpath contains all Synthetica libraries (including
   Synthetica's core library 'synthetica.jar').

2. Enable the Synthetica Look and Feel at startup time in your application:

    import de.javasoft.plaf.synthetica.SyntheticaBlackMoonLookAndFeel;

    try 
    {
      UIManager.setLookAndFeel(new SyntheticaBlackMoonLookAndFeel());
    } 
    catch (Exception e) 
    {
      e.printStackTrace();
    }    

Answer 1

It means you are missing dependant classes. If you look at the requirements it also requires "Synthetica Standard Look and Feel"

you can download it here

Answer 2

If you have downloaded the .jar -file, then you need to add it to your build path in eclipse.

Ie if you in your eclipse project have a directory lib where you put your .jar -files, then right-click on your jar-file and chose Build Path then Add to Build Path .

Answer 3

I know that the issue might have been resolved as this is a very old post, but as this may contribute other current users (like myself):

• First you must add the Synthetica.jar first then add a theme. To downlaod Synthetica.jar visit this link : jyloo.com/synthetica/download .To download a theme try jyloo.com/synthetica/themes
• Right-click on you project and click on "Properties"
• On Java Build Path , select the third tab and the click "Add JARs" or "Add External JARs..." and locate the .jar files and the click "Open"

• Click "Ok" and the to enable theme, you can use this code:

   try { UIManager.setLookAndFeel(new SyntheticaBlueMoonLookAndFeel()); } catch (Exception e) { e.printStackTrace(); }
