Re: [JAVA2D] How to use BufferStrategy with JApplet?
Hi, I don't think using JApplet won't help you much. The only reason I think it may make a difference is that JApplets in 6u10 disable the clearing of the background on resize. I would suggest not to do multi-threaded rendering, it's generally a bad idea. You don't get any advantage from doing so, but the rendering code will be too complicated. One thing you should do when using BS is disable repaints (setIgnoreRepaint()) - it may help. Thanks, Dmitri [EMAIL PROTECTED] wrote: Hi Dmitri, Well I have been quite happy to use an Applet but I found that it's very problematic to avoid flickering on resizing when there are more than one rendering threads.

Anyway, this isn't happening in my JFrame implementation of the same program so I figured that perhaps if I change over to using JApplet and JPanel instead of Applet and Canvas then maybe the problem would go away. I have now managed to minimize the flickering by doing a full re-render when a resize is detected and the second thread is active. There is still a small degree of flickering but it is probably acceptable and as good as it is going to get :-) === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message signoff JAVA2D-INTEREST.

Re: [JAVA2D] How to use BufferStrategy with JApplet?
OK thanks Dmitri. Unfortunately using setIgnoreRepaint() doesn't help. My multithreaded rendering is working very nicely and in some ways is less complex than putting it all in one thread. I think I will just live with the small amount of flickering on resize that I have now. -- And loving it, -Qu0ll (Rare, not extinct) _ [EMAIL PROTECTED] [Replace the SixFour with numbers to email me] [Message sent by forum member 'qu0ll' (qu0ll)] http://forums.java.net/jive/thread.jspa?messageID=289436 === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message signoff JAVA2D-INTEREST.

Re: [JAVA2D] How to use BufferStrategy with JApplet?
May be you could suspend some of your rendering when resizing? Add a component event listener to the Japplet, and pause your rendering thread - may be it'll help.

Gosh Dmitri - it was that simple! Why didn't I think of that?

Re: [JAVA2D] How to use BufferStrategy with JApplet?
Why would you want to use your own BufferStrategy with a JApplet? Why not use Applet?
