nudsfml.graphics.renderwindow

RenderWindow is the main class of the Graphics package. It defines an OS window that can be painted using the other classes of the graphics module.

RenderWindow is derived from $(WINDOW_LINK), thus it inherits all its features : events, window management, OpenGL rendering, etc. See the documentation of $(WINDOW_LINK) for a more complete description of all these features, as well as code examples.

On top of that, RenderWindow adds more features related to 2D drawing with the graphics module (see its base class $(RENDERTARGET_LINK) for more details).

Here is a typical rendering and event loop with a RenderWindow:

// Declare and create a new render-window
auto window = new RenderWindow(VideoMode(800, 600), "DSFML window");

// Limit the framerate to 60 frames per second (this step is optional)
window.setFramerateLimit(60);

// The main loop - ends as soon as the window is closed
while (window.isOpen())
{
   // Event processing
   Event event;
   while (window.pollEvent(event))
   {
       // Request for closing the window
       if (event.type == Event.Type.Closed)
           window.close();
   }

   // Clear the whole window before rendering a new frame
   window.clear();

   // Draw some graphical entities
   window.draw(sprite);
   window.draw(circle);
   window.draw(text);

   // End the current frame and display its contents on screen
   window.display();
}

$(PARA Like $(WINDOW_LINK), $(U RenderWindow) is still able to render direct OpenGL stuff. It is even possible to mix together OpenGL calls and regular DSFML drawing commands.)

// Create the render window
auto window = new RenderWindow(VideoMode(800, 600), "DSFML OpenGL");

// Create a sprite and a text to display
auto sprite = new Sprite();
auto text = new Text();
...

// Perform OpenGL initializations
glMatrixMode(GL_PROJECTION);
...

// Start the rendering loop
while (window.isOpen())
{
    // Process events
    ...

    // Draw a background sprite
    window.pushGLStates();
    window.draw(sprite);
    window.popGLStates();

    // Draw a 3D object using OpenGL
    glBegin(GL_QUADS);
        glVertex3f(...);
        ...
    glEnd();

    // Draw text on top of the 3D object
    window.pushGLStates();
    window.draw(text);
    window.popGLStates();

    // Finally, display the rendered frame on screen
    window.display();
}
