#4422 — Strange problem with JAVA

  To: comp.lang.java.gui
Hi All,

  I have a strange problem with my JAVA GUIs running on GNOME desktop.
The GUIs appear broken(No static text is displayed) when I am running
my application with Java 1.4 or 1.5 but appear to be running fine when
I use Java1.6. The dialogs are created using JOptionDialog and the
parent frame(JFrame) has a look and feel set by getSystemLookAndFeel.
The issues got fixed to an extent by using metalLookAndFeel but still
dialogs are not behaving correctly.

When using Java 1.4 or 1.5 if I resize the dialog then the information
on the dialog shows up but this is creating application entirely
unusable.

Unfortunately, I am unable to post any code on the forum :(

In case anybody has come across such issue earlier or can point me to
some way to fix it will be highly appreciated.

Thanks in advance!

~Deepanshu

You probably use some API which has only been introduced in 1.6 and thus
does not work, or only partially works in older versions.

That will make it very difficult to help you.

The whole set of applications have been developed using Java 1.4. its
only after trying on Gnome we found out that this does not work.

I will try to create a prototype as fast as I can.

Is all of the GUI creation, and updating, done on the EDT? Creating or updating
any GUI component from any other thread is liable to cause unpredictable
drawing problems.

In my experience the GTK Look & Feel that is selected on the Gnome Desktop behaves completely different compared e.g. to the Metal Look & Feel. I had several cases were the order of events during creation of my Windows and Panels were different compared to other look and feels and thus certain objects were not yet initialized which led to NPEs during startup and opening of windows.

This is a compelling observation. I wonder if it's related to Nigel 
Wade's reminder about constructing GUI components on the EDT:

The creation of the objects was done in the EDT but if memory serves me well (it's been a while since I hunted that down) this was also caused when adding listeners. The order in which certain events were dispatched to the listeners were completely different. I'm not talking about multiple listeners on the same event. Those were different types of listeners.

Perhaps listeners were using a published 'this' from the constructor?

WAG given I have no data.

Besides the reasons others already mentioned:

- EDT
- AWT/Swing mixture
- ...

I also would consider something like Compiz/Beryl to be a reasonable candidate 
that might be in your way. I experienced a lot of weird GUI behaviour (basically 
not drawing components or entire windows) with compiz enabled. If you have 
Desktop effects enabled via compiz try to deactivate them and try again.

HI Stefan,
  Could you please point me to how can I disable these.

Thanks,
