how to bind a bitmap to texture in QT?

[saman_artorious]

As far as it is relevant to the current problem:

I want to get RGB values from a 24 bit BGR data. This data is from a raw image without a header.
I don't know how to convert the index of the buffer to its corresponding RGB values.
here is what I have done:

window_width  = 800;
 
    window_height = 600;
 
    size = window_width * window_height;
 
    pixels = new float[size*3];
 
    for(int i = 0, j = 0; i < size*3, j < size; i += 3, j++)
    {
        pixels[i+2] = bytes[i];
    }
 
    updateGL();

window_width  = 800;

    window_height = 600;

    size = window_width * window_height;

    pixels = new float[size*3];

    for(int i = 0, j = 0; i < size*3, j < size; i += 3, j++)
    {
        pixels[i+2] = bytes[i];
    }

    updateGL();

To copy to clipboard, switch view to plain text mode 

void GlWidget:aintGL()
{

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glDrawPixels(window_width,window_height,GL_RGB,GL_ FLOAT,pixels);
}

what am i missing?
