Help with Qt and SDL

[bottin]

Hi all,

I try to use SDL lib in a Qt Project using a Visual Studio 2008, but i cant use SDL with QT.

In SDL i make this function

void setpixel(SDL_Surface *screen, int x, int y, Uint8 r, Uint8 g, Uint8 b)
{
    Uint32 *pixmem32;
    Uint32 colour; 
 
    colour = SDL_MapRGB( screen->format, r, g, b );
 
    pixmem32 = (Uint32*) screen->pixels  + y + x;
    *pixmem32 = colour;
}

void setpixel(SDL_Surface *screen, int x, int y, Uint8 r, Uint8 g, Uint8 b)
{
    Uint32 *pixmem32;
    Uint32 colour; 

    colour = SDL_MapRGB( screen->format, r, g, b );

    pixmem32 = (Uint32*) screen->pixels  + y + x;
    *pixmem32 = colour;
}

To copy to clipboard, switch view to plain text mode 

now i cant use this function on Qt, does anyone know how i can use SDL with Qt or how i can modify this function to work on Qt?

Thanks for all!

What is it supposed to do?

Use SDL and Qt is a bad idea. Both of them have their own event and windowing system. Try to use QGLWidget or try to look for a wrapper.

I have a sparse matrix with a range between -inf to inf, this function paint in a blank image diferents colors for each number of matrix.

In that case, the best and easiest choice is to use QGLWidget.
