JVx Vaadin UI and Vaadin 8.1

Our JVx Vaadin UI is based on vaadin 7.7.9 right now. It works great but vaadin moves forward in big steps. The latest 8.1 release contains many new features and bugfixes. Not all fixes were backported to vaadin 7. This is bad but clear for us.

So we should switch to vaadin 8.1?

This isn't an easy task because vaadin 8 has some new APIs and vaadin moved some parts like FontAwesome to new AddOns. The ContextMenu AddOn was compatible up to vaadin 7, but 8 needs the new official ContextMenu AddOn. The data bindings will work with 8 but needs a compatibility layer.

But anyway, we decided to start the migration and will do everything step-by-step. The first task will do the update of all our vaadin projects to Java 8 and vaadin 8.1. The next step will do the integration of v7 compatibility layer and the following tasks will fix all other problems like ContextMenu, FontAwesome, changed APIs. It's a bigger project and we hopefully will be finished by the end of October.

This blog post is a notice for our vaadin UI users!

We'll keep you up to date :)

Full-Screen Mode for JVx applications

If you have a JVx application and want to use it without the frame border, it's not supported out-of-the-box. Sometimes it's very useful to have a full-screen application or to grab a screenshot without frame.

We now support this feature for Swing based applications but not in the official UI API. Here's a code snippet:

//F12 for toggling mode
KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDispatcher(new KeyEventDispatcher()
{
      @Override
      public boolean dispatchKeyEvent(KeyEvent e)
      {
          if (e.getKeyCode() == KeyEvent.VK_F12)
          {
              if (ObjectCache.get("FULLSCREEN") == null)
              {
                  ObjectCache.put("FULLSCREEN", Boolean.TRUE, 500);
                 
                  SwingApplication app = (SwingApplication)getLauncher();
                  app.setFullScreen(!app.isFullScreen());
                 
                  return true;
              }
             
              return false;
          }
         
          return false;
      }
});

The trick with FULLSCREEN is necessary because the event fires sometimes more than once.

Simply press F12 key to toggle between Fullscreen/Frame mode.

Vaadin AddOn for VisionX

We have a new AddOn for all VisionX users. It's the Vaadin AddOn.

The new AddOn makes it possible to integrate Vaadin AddOns from the official Vaadin AddOn Directory. It makes the integration super simple because we solved the technical problems. The AddOn does all the hard work for you and after two button clicks, everything is done.

With our new AddOn, we introduced more new VisionX features. In the next update release, it will be possible to create AddOns which have access to VisionX itself. Use the internal DataBooks or the Designer, the WizardManager and all other APIs. It'll be possible to create your own VisionX based on VisionX!

Also new is the automatic restart feature. It's possible to restart VisionX after installing an AddOn or Module with a simple button click. This feature is the base for automatic VisionX updates. Currently, we don't update VisionX automatically, but we think it will be nice for one of the next versions.
