Integrating

Integrating LEXSDL in a existing project is easy.
The only thing necessary is having access to the raw SDL_Window and SDL_Renderer.
Bellow are examples on how to do it.
The functions to be used are:

LEXSDL_SetWindow();

LEXSDL_SetRenderer();

C

This example can be run after clonning the repo as "make integrating"

#include<SDL2/SDL.h>
#include<LEXSDL/LEXSDL.h>

int

(

void

){

// this window and renderer would arleady be integrated in your code in some way.

(

"LEXSDL C Example - Integrating"

800

600

);

(

-1

);

// set the window and renderer.

(

);

(

);

//now functions of LEXSDL that depend on the renderer and window can be used.

//set the background to a pink color.

(

0xee

0x70

0xb5

0xFF

);

// and render

();

// sleep for 3 seconds

(

);

}

Rust

This example can be run after clonning the repo as "cargo run --example integrating"


 use lexsdl::*;

 

 fn main(){

 	    // initialize sdl

 	    let sdl_context = sdl2::init().unwrap();

 	    let video_subsystem = sdl_context.video().unwrap();

 	

 	    // create window and canvas

 	    let window = video_subsystem.window("LEXSDL Rust Example - integrating", 800,600).position_centered().build().unwrap();

 	    let mut canvas = window.into_canvas().build().unwrap();

 	

 	    // to integrate

 	    unsafe {

 		        // get the window pointer out of the canvas and set it.

 		        LEXSDL_SetWindow(canvas.window_mut().raw());

 		        // get the renderer pointer out of the canvas and set it.

 		        LEXSDL_SetRenderer(canvas.raw());

 	    }

 	

 	    // now LEXSDL can be normally used.

 	    unsafe {

 		        // set the backgroud to a lime color.

 		        LEXSDL_SetBackgroundColor(0x7D,0xBF,0x2F,0xFF);

 		

 		        // and render

 		        LEXSDL_NewFrame();

 		        LEXSDL_ShowFrame();

 	    }

 	

 	    // sleep for 3 seconds before exiting.

 	    std::thread::sleep(std::time::Duration::from_secs(3));
