Screen flicker ,How to solve? The following code



private Canvas canvas = null;
...

buffer = new FrameBuffer(GanmeConfig.WIDTH, GanmeConfig.HEIGHT, FrameBuffer.SAMPLINGMODE_NORMAL);
buffer.disableRenderer(IRenderer.RENDERER_SOFTWARE);
buffer.enableRenderer(IRenderer.RENDERER_OPENGL, IRenderer.MODE_OPENGL);

canvas = buffer.enableGLCanvasRenderer();
canvas.setBounds(0, 0, GanmeConfig.WIDTH, GanmeConfig.HEIGHT);
frame.add(canvas);

...
while(flag){
....
   buffer.clear();
   sh.updateShadowMap();
   sh.drawScene();
   skybox.render(world, buffer);
   buffer.clearZBufferOnly();
   world.renderScene(buffer);
   world.draw(buffer);
   buffer.update();
   buffer.displayGLOnly();
   //////////////////
   canvas.repaint(); 
   Thread.sleep(14);
   }
   buffer.dispose();
   frame.dispose();

You have two renderers active with this setup. They to leave out the enableRenderer for the GLRenderer to see if that helps.
Apart from that, i don't get your render loop...why are you using drawScene in the ShadowHelper and in addition, you are also rendering the world itself? That doesn't make any sense exception if the ShadowHelper uses a different world. If not, this is just wrong...

 To solve the canvas flicker?  Canvas double buffer?

[EgonOlsen]

I don't think so. Just have a look at the AWTGL example what comes with the distribution. Apart from that, you seem to ignore my former post, which contains some ideas on how to fix this.

I want to use the OpenGL window, but many controls need to write their own. For example, I need a text input China text whether to support the input method?

Reference to what? The example that i mentioned can be found in the jpct.zip.

As said: There's an example in the distribution that doesn't flicker. You can build upon that and see what's wrong with your code. And i mentioned that your render loop is most likely wrong. I don't see how i'm supposed to provide a kind of "reference url" to anything...
