Hi, i try to setup a fullscreenmode, but i dont see anythink on the screen. Here is my setupcode

Code:

CGDisplayErr err;

    //capture main display

    err = CGDisplayCapture(kCGDirectMainDisplay);     

    NSAssert(err == CGDisplayNoErr, @"Error CGDisplayCapture");

    //Get best Mode

    CFDictionaryRef newMode = CGDisplayBestModeForParameters(kCGDirectMainDisplay, 24, _screenWidth, _screenHeight, NULL);

    NSAssert(err == CGDisplayNoErr, @"Error CGDisplayBestModeForParameters");

    //Switch to selected resolution.

    err = CGDisplaySwitchToMode(kCGDirectMainDisplay, newMode);

    NSAssert(err == CGDisplayNoErr, @"Error CGDisplaySwitchToMode");

    NSOpenGLPixelFormatAttribute attr[] = {

        NSOpenGLPFADoubleBuffer,

        NSOpenGLPFAAccelerated,

        NSOpenGLPFAColorSize, 24,

        NSOpenGLPFADepthSize, 16,

        NSOpenGLPFAFullScreen,

        NSOpenGLPFAScreenMask,CGDisplayIDToOpenGLDisplayMask(kCGDirectMainDisplay),​

    0 };    

    NSOpenGLPixelFormat *nsglFormat = [[NSOpenGLPixelFormat alloc] initWithAttributes:attr];

    _context = [[NSOpenGLContext alloc] initWithFormat: nsglFormat shareContext: nil];

    [nsglFormat release];

    //set openGL context to draw to screen    

    [_context setFullScreen];     

    [_context makeCurrentContext];

here my rendercode

Code:

glViewport( 0, 0, _screenWidth, _screenHeight);

        glMatrixMode( GL_PROJECTION );

        glLoadIdentity();

        gluPerspective( 45.0, _screenWidth/_screenHeight, 1.0, 5.0 );

        glMatrixMode( GL_MODELVIEW );

        glLoadIdentity();

        glClear(GL_COLOR_BUFFER_BIT);    

        glColor3f(1.0f, 0.85f, 0.35f);

        glBegin(GL_TRIANGLES);

        {

            glVertex3f( -0.2, -0.3, -2.0);

            glVertex3f(  0.2, -0.3, -2.0);

            glVertex3f(  0.0,  0.3, -2.0);

        }

        glEnd();

        //glFlush(); 

        [_context flushBuffer];

there are no errors.
any suggestions?

using Xcode 3? Maybe it couldn't be bothered compiling the last change to your source for a while...
