~~Title: Customize an Application Without Derivation~~

If you use a standard ProjX application and want to change the appearance without derivation, you have the following options:

  * Create your own application class that extends ProjX
  * Create a class that implements IApplicationSetup to configure the application for your needs
  * Create a class that implements IWorkScreenManager to manage work-screens on your own
  * Use [[jvx:client:gui:application_parameters|application parameters]] to replace predefined classes/implementations

There are the following parameters available:

**Application.setup.classname** to configure ProjX instance \\ 
(set the full qualified class name that implements IApplicationSetup)

**Application.workscreenmanager.classname** to have a custom work-screen handling \\ 
(set the full qualified class name that implements IWorkScreenManager)

**Application.Login.classname** to use a custom login screen \\ 
(set the full qualified class name that implements ILogin)

**Application.Menu.classname** to use a custom menu and/or toolbar \\ 
(set the full qualified class name that extends Menu)

**Application.Error.classname** to use a custom error dialog \\ 
(set the full qualified class name that extends Error)

**Application.theme** to use a custom theme \\ 
(set the full qualified class name that implements ITheme)
