Problem with setUndecorated() method in JFrame

Thread view:

And - 24 Aug 2006 10:19 GMT

Hi,
I have a problem using the method in subject in my Java app. There's a
JFrame with backgound image (JLabel tip...) and several JDIC WebBrowser
(java.awt.Canvas) disposed on it at runtime, following position and
dimension rules on a xml file. This app works fine in fullscreen mode
using the method setFullScreenWindow(this) of GraphicsDevice, but it
does only if the frame is decorated: using setUndecorated(true) on my
JFrame cause bad rendering of components on the stage. It seems that
the background image overlap the browsers...but it have a strange a
different behaviour any time. All works well if the frame is
decorated... :-/
If you would like to help me I can provide any detail of my source !
Thank you very much, bye!!!!

You may be having problems with the lightweight/heavyweight components.
Try changing your JFrame to a Frame and see if that helps. If not
please post a simple working example of your problem.

Thank you for your answer!
I've just posted my specific problem on JDIC Forum...i'm not sure my
real problem is the use of setUndecorated method, but as you suggested
me, the mixed use of heavy and light components. (I read this
interesting arcticle:
http://java.sun.com/products/jfc/tsc/articles/mixing/).
I would like to know if this strange behaviour is due to my wrong
source...i'm rather new in "gui world"...here you can find a scrap of
code:

Thank you very much!! Bye!!!

You are going to have to post a compilable example that demonstrates
your problem. I can't tell from the partial code above where your
problem is. Also you code is very hard to read without some indentation.

Ok...i missed the import statements...but there's a complete class,
with main method: what should i have to add?

>Also you code is very hard to read without some indentation.

I'm sorry, but i though that every IDE should have "format" and
"organize import" functions...and it probably doesn't compile due to
the dipendency on JDIC libraries...

I'd make it so that readers can cut text from your posting, save it to a
file and compile it with javac to make a working program that they can
run without them having to add anything. Have you heard of the idea of a
"Small Self-Contained Compilable Example" (SSCCE)?

OK, but firstly you are cutting yourself off from help by people who can
see where you are going wrong by simply reading the post here without
going to the effort of pasting it into an IDE and reformatting it.

Secondly, when posting a question, I think its better I spend 10 mins
formatting my example than expect 100 people spend 10 mins each
formatting my example (total 16.5 hours of their time wasted).

I find that the more work I ask make people to do (for free) the less
likely they are to be motivated to help. I'd spend the time to make it
easier for them to help me.

I'd spend a few minutes creating an example that shows the problem
without using JDIC libraries.

I agree with you.

No doubt about this, but i'm rather astonished of the text editor of
java.net.Forum: i usually have a daily activity on Usenet, i always try
to pay attention to quote and to provide the best way to read my
posts...i have to admit i was victim of hurry! :-/ :-)

I think it too, see above...

Good...so can you suggest me any tips about building guis and avoid
errors like that one?
Thank you for the time you spent on this post, bye!
