I am new to JVx and I was trying out the "The JVx Application".
The application shows up when I run it but I can't focus either the Username field or the Password field!
My Java version is 1.8.0_66

Do you mean this application: http://www.sibvisions.com/en/jvxmdocume ... helloworld
and this download: http://sourceforge.net/projects/jvxfirstapp/

Did you try a JVM 7? Shouldn't make a difference, but nevertheless...

I was following the tutorial at http://www.sibvisions.com/en/jvxmdocumentation/86-jvxfirstappl
I forgot to mention that I am using Oracle Java under Linux OS (Ubuntu). Was this tested on any Linux desktop?

I like the concepts of JVx and may not use the Swing GUI. Eventually, if I use it, it will be with browser/mobile GUI. (Also, I am a Vaadin fan, so the browser front-end will be the Vaadin one).

However, it will be nice to see the Swing GUI also working.

OK. Yes, we made tests with Linux (Ubuntu 10.04, 11.04, 12.04.1, 13.10; CentOS 5.3) and Sun/Oracle JDK. But we had some problems with window manager. We should repeat our tests in the next days. Thanks for the Information.

You could try a simple JFrame and JDesktopPane with an JInternalFrame and JTextField, JPasswordField, because JVx shouldn't make a difference - it's more or less the abstraction layer for different UI technologies.

Swing for the browser aka Applets are "dead". Webstart is still a valid technology. But the technology shouldn't matter if you use JVx. JavaFX is also a nice UI technology.


Which Ubuntu version do you use?

We made a test with Ubuntu 13.10 and didn't have any problems.

Here's a screenshot:




Which Ubuntu version do you use?

Also no problems with current Ubuntu 15.10:

We used jdk 1.8.0_74 from java.oracle.com for the tests. Looks like a specific problem with your system.

Sorry, I was away for few days.

I tried on my Ubuntu 15.10 machine with jdk1.8.0_74 now and still I can't get the focus there!

By the by, I have many of my Swing applications on this machine, running with out any issues. I will see if I can test on some other machine.

Very strange.

Do you use the standard desktop environment, Unity? or a custom LaF for the Swing application.
In our case, everything is standard: Unity, LaF... (we setup a fresh Ubuntu VM, without manual customization).

Would be great if you find out the difference, because we have no problems in our test environment.

Yes, I do use a standard Ubuntu installation with no customization!

Thanks, seems to be fixed now for me too. had to stop using it for a while.

The problem occured again and we were able to reproduce and fix it: InternalFrame not focusable
