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. -- Knute Johnson email s/nospam/knute/ Back to top And Guest Posted: Wed Aug 30, 2006 9:37 pm    Post subject: Re: Problem with setUndecorated() method in JFrame Knute Johnson ha scritto: Quote: You may be having problems with the lightweight/heavyweight components.

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: http://forums.java.net/jive/thread.jspa?threadID=17931&tstart=0 Thank you very much!! Bye!!!

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. -- Knute Johnson email s/nospam/knute/ Back to top And Guest Posted: Thu Aug 31, 2006 12:44 pm    Post subject: Re: Problem with setUndecorated() method in JFrame Knute Johnson ha scritto: Quote: You are going to have to post a compilable example that demonstrates your problem.

Quote: 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)? Quote: 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... 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. Quote: and it probably doesn't compile due to the dipendency on JDIC libraries... I'd spend a few minutes creating an example that shows the problem without using JDIC libraries.

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! :-/ :-) Quote: 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 think it too, see above... Quote: I'd spend a few minutes creating an example that shows the problem without using JDIC libraries. 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!
