The code block(s) should be between ```c and ``` tags:
/*Create a display*/
static lv_disp_drv_t disp_drv;
lv_disp_drv_init(&disp_drv); /*Basic initialization*/
disp_drv.draw_buf = &disp_buf1;
disp_drv.flush_cb = sdl_display_flush;
disp_drv.hor_res = SDL_HOR_RES;
disp_drv.ver_res = SDL_VER_RES;
// disp_drv.screen_transp = 1;
disp_drv.antialiasing = true;
disp_drv.clear_cb = sdl_clear_cb;
disp_drv.direct_mode = 1;
disp_drv.screen_transp = 1;
application
lv_obj_t *cont1 = lv_obj_create(lv_scr_act());
//lv_obj_remove_style_all(cont1);
lv_obj_set_style_bg_opa(lv_scr_act(), 0, LV_PART_MAIN|LV_STATE_DEFAULT);
lv_obj_set_size(cont1, 1024/2, 600);
lv_obj_set_style_bg_opa(cont1, 255, 0);
lv_obj_set_style_bg_color(cont1, lv_color_make(0xff, 0, 0xff),LV_PART_MAIN|LV_STATE_DEFAULT);
application run as follows:
